Class ToXmlGenerator

  • All Implemented Interfaces:
    Versioned, java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable
    public class ToXmlGenerator
extends GeneratorBase
    JsonGenerator that outputs JAXB-style XML output instead of JSON content. Operation requires calling code (usually either standard Jackson serializers, or in some cases (like BeanSerializer) customized ones) to do additional configuration calls beyond regular JsonGenerator API, mostly to pass namespace information.

    • Method Detail

      • initGenerator

        public void initGenerator()
                   throws java.io.IOException
        Method called before writing any other output, to optionally output XML declaration.
        Throws:
        java.io.IOException

      • setPrettyPrinter

        public JsonGenerator setPrettyPrinter​(PrettyPrinter pp)
        Description copied from class: JsonGenerator
        Method for setting a custom pretty printer, which is usually used to add indentation for improved human readability. By default, generator does not do pretty printing.

        To use the default pretty printer that comes with core Jackson distribution, call JsonGenerator.useDefaultPrettyPrinter() instead.

        Overrides:
        setPrettyPrinter in class JsonGenerator
        Parameters:
        pp - PrettyPrinter to assign, if any; null if none
        Returns:
        This generator, to allow call chaining

      • getOutputTarget

        public java.lang.Object getOutputTarget()
        Description copied from class: JsonGenerator
        Method that can be used to get access to object that is used as target for generated output; this is usually either OutputStream or Writer, depending on what generator was constructed with. Note that returned value may be null in some cases; including case where implementation does not want to exposed raw source to caller. In cases where output has been decorated, object returned here is the decorated version; this allows some level of interaction between users of generator and decorator object.

        In general use of this accessor should be considered as "last effort", i.e. only used if no other mechanism is applicable.

        Overrides:
        getOutputTarget in class JsonGenerator
        Returns:
        Output target this generator was configured with

      • getOutputBuffered

        public int getOutputBuffered()
        Stax2 does not expose buffered content amount, so we can only return -1 from here
        Overrides:
        getOutputBuffered in class JsonGenerator
        Returns:
        Amount of content buffered in internal units, if amount known and accessible; -1 if not accessible.

      • overrideFormatFeatures

        public JsonGenerator overrideFormatFeatures​(int values,
                                            int mask)
        Description copied from class: JsonGenerator
        Bulk set method for (re)setting states of FormatFeatures, by specifying values (set / clear) along with a mask, to determine which features to change, if any.

        Default implementation will simply throw an exception to indicate that the generator implementation does not support any FormatFeatures.

        Overrides:
        overrideFormatFeatures in class JsonGenerator
        Parameters:
        values - Bit mask of set/clear state for features to change
        mask - Bit mask of features to change
        Returns:
        This generator, to allow call chaining

      • canWriteFormattedNumbers

        public boolean canWriteFormattedNumbers()
        Description copied from class: JsonGenerator
        Introspection method to call to check whether it is possible to write numbers using JsonGenerator.writeNumber(java.lang.String) using possible custom format, or not. Typically textual formats allow this (and JSON specifically does), whereas binary formats do not allow this (except by writing them as Strings). Usual reason for calling this method is to check whether custom formatting of numbers may be applied by higher-level code (databinding) or not.
        Overrides:
        canWriteFormattedNumbers in class JsonGenerator
        Returns:
        True if this generator is capable of writing "formatted" numbers (and if so, need to be passed using JsonGenerator.writeNumber(String), that is, passed as String); false if not

      • inRoot

        public boolean inRoot()

      • getStaxWriter

        public javax.xml.stream.XMLStreamWriter getStaxWriter()
        Method that allows application direct access to underlying Stax XMLStreamWriter. Note that use of writer is discouraged, and may interfere with processing of this writer; however, occasionally it may be necessary.

        Note: writer instance will always be of type XMLStreamWriter2 (including Typed Access API) so upcasts are safe.

                              javax.xml.namespace.QName wrappedName)
                       throws java.io.IOException
        Methdod called when a structured (collection, array, map) is being output.
        Parameters:
        wrapperName - Element used as wrapper around elements, if any (null if none)
        wrappedName - Element used around individual content items (can not be null)
        Throws:
        java.io.IOException

      • finishWrappedValue

        public void finishWrappedValue​(javax.xml.namespace.QName wrapperName,
                               javax.xml.namespace.QName wrappedName)
                        throws java.io.IOException
        Method called after a structured collection output has completed
        Throws:
        java.io.IOException

        public final void writeFieldName​(java.lang.String name)
                          throws java.io.IOException
        Description copied from class: JsonGenerator
        Method for writing a field name (JSON String surrounded by double quotes: syntactically identical to a JSON String value), possibly decorated by white space if pretty-printing is enabled.

        Field names can only be written in Object context (check out JSON specification for details), when field name is expected (field names alternate with values).

        Specified by:
        writeFieldName in class JsonGenerator
        Parameters:
        name - Field name to write
        Throws:

                                   java.lang.String value)
                            throws java.io.IOException
        Description copied from class: JsonGenerator
        Convenience method for outputting a field entry ("member") that has a String value. Equivalent to: 
          writeFieldName(fieldName);
  writeString(value);
        Overrides:
        writeStringField in class JsonGenerator
        Parameters:
        fieldName - Name of the field to write

                           throws java.io.IOException
        Description copied from class: JsonGenerator
        Method for writing starting marker of a Array value (for JSON this is character '['; plus possible white space decoration if pretty-printing is enabled).

        Array values can be written in any context where values are allowed: meaning everywhere except for when a field name is expected.

        Specified by:
        writeStartArray in class JsonGenerator
        Throws:
        java.io.IOException - if there is either an underlying I/O problem or encoding issue at format layer

      • writeEndArray

        public final void writeEndArray()
                         throws java.io.IOException
        Description copied from class: JsonGenerator
        Method for writing closing marker of a JSON Array value (character ']'; plus possible white space decoration if pretty-printing is enabled).

        Marker can be written if the innermost structured type is Array.

        Specified by:
        writeEndArray in class JsonGenerator
        Throws:
        java.io.IOException - if there is either an underlying I/O problem or encoding issue at format layer

      • writeStartObject

                            throws java.io.IOException
        Description copied from class: JsonGenerator
        Method for writing starting marker of an Object value (character '{'; plus possible white space decoration if pretty-printing is enabled).

        Object values can be written in any context where values are allowed: meaning everywhere except for when a field name is expected.

        Specified by:
        writeStartObject in class JsonGenerator
        Throws:
        java.io.IOException - if there is either an underlying I/O problem or encoding issue at format layer

      • writeEndObject

        public final void writeEndObject()
                          throws java.io.IOException
        Description copied from class: JsonGenerator
        Method for writing closing marker of an Object value (character '}'; plus possible white space decoration if pretty-printing is enabled).

        Marker can be written if the innermost structured type is Object, and the last written event was either a complete value, or START-OBJECT marker (see JSON specification for more details).

        Specified by:
        writeEndObject in class JsonGenerator
        Throws:
        java.io.IOException - if there is either an underlying I/O problem or encoding issue at format layer

      • writeFieldName

        public void writeFieldName​(SerializableString name)
                    throws java.io.IOException
        Description copied from class: JsonGenerator
        Method similar to JsonGenerator.writeFieldName(String), main difference being that it may perform better as some of processing (such as quoting of certain characters, or encoding into external encoding if supported by generator) can be done just once and reused for later calls.

        Default implementation simple uses unprocessed name container in serialized String; implementations are strongly encouraged to make use of more efficient methods argument object has.

        Overrides:
        writeFieldName in class GeneratorBase
        Parameters:
        name - Field name to write
        Throws:
        java.io.IOException - if there is either an underlying I/O problem or encoding issue at format layer

      • writeString

        public void writeString​(java.lang.String text)
                 throws java.io.IOException
        Description copied from class: JsonGenerator
        Method for outputting a String value. Depending on context this means either array element, (object) field value or a stand alone String; but in all cases, String will be surrounded in double quotes, and contents will be properly escaped as required by JSON specification.
        Specified by:
        writeString in class JsonGenerator
        Parameters:
        text - Text value to write
        Throws:
        java.io.IOException - if there is either an underlying I/O problem or encoding issue at format layer

      • writeString

        public void writeString​(char[] text,
                        int offset,
                        int len)
                 throws java.io.IOException
        Description copied from class: JsonGenerator
        Method for outputting a String value. Depending on context this means either array element, (object) field value or a stand alone String; but in all cases, String will be surrounded in double quotes, and contents will be properly escaped as required by JSON specification.
        Specified by:
        writeString in class JsonGenerator
        Parameters:
        text - Buffer that contains String value to write
        offset - Offset in buffer of the first character of String value to write
        len - Length of the String value (in characters) to write
        Throws:
        java.io.IOException - if there is either an underlying I/O problem or encoding issue at format layer

      • writeString

        public void writeString​(SerializableString text)
                 throws java.io.IOException
        Description copied from class: JsonGenerator
        Method similar to JsonGenerator.writeString(String), but that takes SerializableString which can make this potentially more efficient to call as generator may be able to reuse quoted and/or encoded representation.

        Default implementation just calls JsonGenerator.writeString(String); sub-classes should override it with more efficient implementation if possible.

        Overrides:
        writeString in class GeneratorBase
        Parameters:
        text - Pre-encoded String value to write
        Throws:
        java.io.IOException - if there is either an underlying I/O problem or encoding issue at format layer

      • writeRawUTF8String

        public void writeRawUTF8String​(byte[] text,
                               int offset,
                               int length)
                        throws java.io.IOException
        Description copied from class: JsonGenerator
        Method similar to JsonGenerator.writeString(String) but that takes as its input a UTF-8 encoded String that is to be output as-is, without additional escaping (type of which depends on data format; backslashes for JSON). However, quoting that data format requires (like double-quotes for JSON) will be added around the value if and as necessary.

        Note that some backends may choose not to support this method: for example, if underlying destination is a Writer using this method would require UTF-8 decoding. If so, implementation may instead choose to throw a UnsupportedOperationException due to ineffectiveness of having to decode input.

        Specified by:
        writeRawUTF8String in class JsonGenerator
        Parameters:
        text - Buffer that contains String value to write
        offset - Offset in buffer of the first byte of String value to write
        length - Length of the String value (in characters) to write
        Throws:
        java.io.IOException - if there is either an underlying I/O problem or encoding issue at format layer

      • writeUTF8String

        public void writeUTF8String​(byte[] text,
                            int offset,
                            int length)
                     throws java.io.IOException
        Description copied from class: JsonGenerator
        Method similar to JsonGenerator.writeString(String) but that takes as its input a UTF-8 encoded String which has not been escaped using whatever escaping scheme data format requires (for JSON that is backslash-escaping for control characters and double-quotes; for other formats something else). This means that textual JSON backends need to check if value needs JSON escaping, but otherwise can just be copied as is to output. Also, quoting that data format requires (like double-quotes for JSON) will be added around the value if and as necessary.

        Note that some backends may choose not to support this method: for example, if underlying destination is a Writer using this method would require UTF-8 decoding. In this case generator implementation may instead choose to throw a UnsupportedOperationException due to ineffectiveness of having to decode input.

        Specified by:
        writeUTF8String in class JsonGenerator
        Parameters:
        text - Buffer that contains String value to write
        offset - Offset in buffer of the first byte of String value to write
        length - Length of the String value (in characters) to write
        Throws:
        java.io.IOException - if there is either an underlying I/O problem or encoding issue at format layer

                   throws java.io.IOException
        Description copied from class: JsonGenerator
        Method that will force generator to copy input text verbatim without any modifications, but assuming it must constitute a single legal JSON value (number, string, boolean, null, Array or List). Assuming this, proper separators are added if and as needed (comma or colon), and generator state updated to reflect this.
        Overrides:
        writeRawValue in class GeneratorBase
        Parameters:
        text - Textual contents to included in output

        Method that will output given chunk of binary data as base64 encoded, as a complete String value (surrounded by double quotes). This method defaults

        Note: because JSON Strings can not contain unescaped linefeeds, if linefeeds are included (as per last argument), they must be escaped. This adds overhead for decoding without improving readability. Alternatively if linefeeds are not included, resulting String value may violate the requirement of base64 RFC which mandates line-length of 76 characters and use of linefeeds. However, all JsonParser implementations are required to accept such "long line base64"; as do typical production-level base64 decoders.

        Specified by:
        writeBinary in class JsonGenerator
        Parameters:
        b64variant - Base64 variant to use: defines details such as whether padding is used (and if so, using which character); what is the maximum line length before adding linefeed, and also the underlying alphabet to use.
        data - Buffer that contains binary data to write
        offset - Offset in data of the first byte of data to write
        len - Length of data to write
        Throws:
        java.io.IOException - if there is either an underlying I/O problem or encoding issue at format layer

      • writeBinary

        public int writeBinary​(Base64Variant b64variant,
                       java.io.InputStream data,
                       int dataLength)
                throws java.io.IOException
        Description copied from class: JsonGenerator
        Method similar to JsonGenerator.writeBinary(Base64Variant,byte[],int,int), but where input is provided through a stream, allowing for incremental writes without holding the whole input in memory.
        Overrides:
        writeBinary in class GeneratorBase
        Parameters:
        b64variant - Base64 variant to use
        data - InputStream to use for reading binary data to write. Will not be closed after successful write operation
        dataLength - (optional) number of bytes that will be available; or -1 to be indicate it is not known. If a positive length is given, data MUST provide at least that many bytes: if not, an exception will be thrown. Note that implementations need not support cases where length is not known in advance; this depends on underlying data format: JSON output does NOT require length, other formats may.
        Returns:
        Number of bytes read from data and written as binary payload
        Throws:
        java.io.IOException - if there is either an underlying I/O problem or encoding issue at format layer

      • writeNumber

        public void writeNumber​(java.lang.String encodedValue)
                 throws java.io.IOException,
                        java.lang.UnsupportedOperationException
        Description copied from class: JsonGenerator
        Write method that can be used for custom numeric types that can not be (easily?) converted to "standard" Java number types. Because numbers are not surrounded by double quotes, regular JsonGenerator.writeString(java.lang.String) method can not be used; nor JsonGenerator.writeRaw(java.lang.String) because that does not properly handle value separators needed in Array or Object contexts.

        Note: because of lack of type safety, some generator implementations may not be able to implement this method. For example, if a binary JSON format is used, it may require type information for encoding; similarly for generator-wrappers around Java objects or JSON nodes. If implementation does not implement this method, it needs to throw UnsupportedOperationException.

        Specified by:
        writeNumber in class JsonGenerator
        Parameters:
        encodedValue - Textual (possibly format) number representation to write
        Throws:
        java.io.IOException - if there is either an underlying I/O problem or encoding issue at format layer
        java.lang.UnsupportedOperationException - If underlying data format does not support numbers serialized textually AND if generator is not allowed to just output a String instead (Schema-based formats may require actual number, for example)

      • flush

        public void flush()
           throws java.io.IOException
        Description copied from class: JsonGenerator
        Method called to flush any buffered content to the underlying target (output stream, writer), and to flush the target itself as well.
        Specified by:
        flush in interface java.io.Flushable
        Specified by:
        flush in class GeneratorBase
        Throws:
        java.io.IOException - if there is either an underlying I/O problem or encoding issue at format layer

      • close

        public void close()
           throws java.io.IOException
        Description copied from class: JsonGenerator
        Method called to close this generator, so that no more content can be written.

        Whether the underlying target (stream, writer) gets closed depends on whether this generator either manages the target (i.e. is the only one with access to the target -- case if caller passes a reference to the resource such as File, but not stream); or has feature JsonGenerator.Feature.AUTO_CLOSE_TARGET enabled. If either of above is true, the target is also closed. Otherwise (not managing, feature not enabled), target is not closed.

        Specified by:
        close in interface java.lang.AutoCloseable
        Specified by:
        close in interface java.io.Closeable
        Overrides:
        close in class GeneratorBase
        Throws:
        java.io.IOException - if there is either an underlying I/O problem
