-
writeFieldName
public void writeFieldName(SerializableString name) throws java.io.IOException

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 value) throws java.io.IOExceptionDescription copied from class:JsonGeneratorMethod for outputting a String value.

writeString
public void writeString(SerializableString value) throws java.io.IOException
Description copied from class:JsonGeneratorMethod similar toJsonGenerator.writeString(String), but that takesSerializableStringwhich 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:
writeStringin classJsonGeneratorDelegate- Parameters:
value- 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
-
writeString
public void writeString(java.io.Reader reader, int len) throws java.io.IOExceptionDescription copied from class:JsonGeneratorMethod 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. Iflenis < 0, then write all contents of the reader. Otherwise, write only len characters.Note: actual length of content available may exceed
lenbut can not be less than it: if not enough content available, aJsonGenerationExceptionwill be thrown.- Overrides:
writeStringin classJsonGeneratorDelegate- Parameters:
reader- Reader to use for reading Text value to writelen- Maximum Length of Text value to read (inchars, non-negative) if known;-1to indicate "read and write it all"- Throws:

-
writeRawUTF8String
public void writeRawUTF8String(byte[] text, int offset, int length) throws java.io.IOExceptionDescription copied from class:JsonGeneratorMethod similar toJsonGenerator.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
Writerusing this method would require UTF-8 decoding. If so, implementation may instead choose to throw aUnsupportedOperationExceptiondue to ineffectiveness of having to decode input.- Overrides:
writeRawUTF8Stringin classJsonGeneratorDelegate- Parameters:
text- Buffer that contains String value to writeoffset- Offset inbufferof the first byte of String value to writelength- 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.IOExceptionDescription copied from class:JsonGeneratorMethod similar toJsonGenerator.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
Writerusing this method would require UTF-8 decoding. In this case generator implementation may instead choose to throw aUnsupportedOperationExceptiondue to ineffectiveness of having to decode input.- Overrides:
writeUTF8Stringin classJsonGeneratorDelegate- Parameters:
text- Buffer that contains String value to writeoffset- Offset inbufferof the first byte of String value to writelength- Length of the String value (in characters) to write- Throws:

Description copied from class:JsonGeneratorMethod that will force generator to copy input text verbatim with no modifications (including that no escaping is done and no separators are added even if context [array, object] would otherwise require such). If such separators are desired, useJsonGenerator.writeRawValue(String)instead.Note that not all generator implementations necessarily support such by-pass methods: those that do not will throw
UnsupportedOperationException.The default implementation delegates to

writeBinary
public void writeBinary(Base64Variant b64variant, byte[] data, int offset, int len) throws java.io.IOException
Description copied from class:JsonGeneratorMethod that will output given chunk of binary data as base64 encoded, as a complete String value (surrounded by double quotes). This method defaultsNote: 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
JsonParserimplementations are required to accept such "long line base64"; as do typical production-level base64 decoders.- Overrides:
writeBinaryin classJsonGeneratorDelegate- 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 writeoffset- Offset indataof the first byte of data to writelen- 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:JsonGeneratorMethod similar toJsonGenerator.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:
writeBinaryin classJsonGeneratorDelegate- Parameters:
b64variant- Base64 variant to usedata- InputStream to use for reading binary data to write. Will not be closed after successful write operationdataLength- (optional) number of bytes that will be available; or -1 to be indicate it is not known. If a positive length is given,dataMUST 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
dataand 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(float v) throws java.io.IOExceptionDescription copied from class:JsonGeneratorMethod for outputting indicate JSON numeric value. Can be called in any context where a value is expected (Array value, Object field value, root-level value). Additional white space may be added around the value if pretty-printing is enabled.- Overrides:
writeNumberin classJsonGeneratorDelegate- Parameters:
v- Number value to write- Throws:
java.io.IOException- if there is either an underlying I/O problem or encoding issue at format layer
-
writeNumber
public void writeNumber(java.math.BigDecimal v) throws java.io.IOExceptionDescription copied from class:JsonGeneratorMethod for outputting indicate JSON numeric value. Can be called in any context where a value is expected (Array value, Object field value, root-level value). Additional white space may be added around the value if pretty-printing is enabled.- Overrides:
writeNumberin classJsonGeneratorDelegate- Parameters:
v- Number value to write- 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.UnsupportedOperationExceptionDescription copied from class:JsonGeneratorWrite 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, regularJsonGenerator.writeString(java.lang.String)method can not be used; norJsonGenerator.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.- Overrides:
writeNumberin classJsonGeneratorDelegate- 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 layerjava.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)
-
writeNumber
public void writeNumber(char[] encodedValueBuffer, int offset, int length) throws java.io.IOException, java.lang.UnsupportedOperationExceptionDescription copied from class:JsonGeneratorOverloaded version ofJsonGenerator.writeNumber(String)with same semantics but possibly more efficient operation.- Overrides:
writeNumberin classJsonGeneratorDelegate- Parameters:
encodedValueBuffer- Buffer that contains the textual number representation to writeoffset- Offset of the first character of value to writelength- Length of the value (in characters) to write- Throws:
java.io.IOException- if there is either an underlying I/O problem or encoding issue at format layerjava.lang.UnsupportedOperationException
-
writeBoolean
public void writeBoolean(boolean v) throws java.io.IOExceptionDescription copied from class:JsonGeneratorMethod for outputting literal JSON boolean value (one of Strings 'true' and 'false'). Can be called in any context where a value is expected (Array value, Object field value, root-level value). Additional white space may be added around the value if pretty-printing is enabled.- Overrides:
writeBooleanin classJsonGeneratorDelegate- Parameters:
v- Boolean value to write- Throws:
java.io.IOException- if there is either an underlying I/O problem or encoding issue at format layer
-
writeNull
public void writeNull() throws java.io.IOExceptionDescription copied from class:JsonGeneratorMethod for outputting literal JSON null value. Can be called in any context where a value is expected (Array value, Object field value, root-level value). Additional white space may be added around the value if pretty-printing is enabled.- Overrides:
writeNullin classJsonGeneratorDelegate- Throws:
java.io.IOException- if there is either an underlying I/O problem or encoding issue at format layer
-
writeOmittedField
public void writeOmittedField(java.lang.String fieldName) throws java.io.IOExceptionDescription copied from class:JsonGeneratorMethod called to indicate that a property in this position was skipped. It is usually only called for generators that returnfalsefromJsonGenerator.canOmitFields().Default implementation does nothing.
- Overrides:
writeOmittedFieldin classJsonGeneratorDelegate- Parameters:
fieldName- Name of the field omitted- Throws:
java.io.IOException- if there is either an underlying I/O problem or encoding issue at format layer
-
writeObjectId
public void writeObjectId(java.lang.Object id) throws java.io.IOExceptionDescription copied from class:JsonGeneratorMethod that can be called to output so-called native Object Id. Note that it may only be called after ensuring this is legal (withJsonGenerator.canWriteObjectId()), as not all data formats have native type id support; and some may only allow them in certain positions or locations. If output is not allowed by the data format in this position, aJsonGenerationExceptionwill be thrown.- Overrides:
writeObjectIdin classJsonGeneratorDelegate- Parameters:
id- Native Object Id to write- Throws:
java.io.IOException- if there is either an underlying I/O problem or encoding issue at format layerJsonGenerationException- if Object ID output is not allowed (either at all, or specifically in this position in output)
-
writeObjectRef
public void writeObjectRef(java.lang.Object id) throws java.io.IOExceptionDescription copied from class:JsonGeneratorMethod that can be called to output references to native Object Ids. Note that it may only be called after ensuring this is legal (withJsonGenerator.canWriteObjectId()), as not all data formats have native type id support; and some may only allow them in certain positions or locations. If output is not allowed by the data format in this position, aJsonGenerationExceptionwill be thrown.- Overrides:
writeObjectRefin classJsonGeneratorDelegate- Parameters:
id- Referenced value, for which Object Id is expected to be written- Throws:
java.io.IOException- if there is either an underlying I/O problem or encoding issue at format layerJsonGenerationException- if Object ID output is not allowed (either at all, or specifically in this position in output)
-
writeTypeId
public void writeTypeId(java.lang.Object id) throws java.io.IOExceptionDescription copied from class:JsonGeneratorMethod that can be called to output so-called native Type Id. Note that it may only be called after ensuring this is legal (withJsonGenerator.canWriteTypeId()), as not all data formats have native type id support; and some may only allow them in certain positions or locations. If output is not allowed by the data format in this position, aJsonGenerationExceptionwill be thrown.- Overrides:
writeTypeIdin classJsonGeneratorDelegate- Parameters:
id- Native Type Id to write- Throws:
java.io.IOException- if there is either an underlying I/O problem or encoding issue at format layerJsonGenerationException- if Type ID output is not allowed (either at all, or specifically in this position in output)
