指定者:

getCodec 在类中 JacksonParser

setCodec

public void setCodec(ObjectCodec c)

从类复制的说明: JacksonParser

Setter that allows defining ObjectCodec associated with this parser, if any. Codec is used by JacksonParser.readValueAs(Class) method (and its variants).

指定者:

setCodec 在类中 JacksonParser

enable

public JacksonParser enable(JacksonParser.Feature f)

从类复制的说明: JacksonParser

Method for enabling specified parser feature (check JacksonParser.Feature for list of features)

覆盖:

enable 在类中 JacksonParser

disable

public JacksonParser disable(JacksonParser.Feature f)

从类复制的说明: JacksonParser

Method for disabling specified feature (check JacksonParser.Feature for list of features)

覆盖:

disable 在类中 JacksonParser

isEnabled

public boolean isEnabled(JacksonParser.Feature f)

从类复制的说明: JacksonParser

Method for checking whether specified JacksonParser.Feature is enabled.

覆盖:

isEnabled 在类中 JacksonParser

setSchema

public void setSchema(FormatSchema schema)

从类复制的说明: JacksonParser

Method to call to make this parser use specified schema. Method must be called before trying to parse any content, right after parser instance has been created. Note that not all parsers support schemas; and those that do usually only accept specific types of schemas: ones defined for data format parser can read.

If parser does not support specified schema, UnsupportedOperationException is thrown.

覆盖:

setSchema 在类中 JacksonParser

参数:

schema - Schema to use

canUseSchema

public boolean canUseSchema(FormatSchema schema)

从类复制的说明: JacksonParser

Method that can be used to verify that given schema can be used with this parser (using JacksonParser.setSchema(org.hotwheel.json.impl.jackson.FormatSchema)).

覆盖:

canUseSchema 在类中 JacksonParser

参数:

schema - Schema to check

返回:

True if this parser can use given schema; false if not

version

public Version version()

从类复制的说明: JacksonParser

Accessor for getting version of the core package, given a parser instance. Left for sub-classes to implement.

指定者:

version 在接口中 Versioned

指定者:

version 在类中 JacksonParser

getInputSource

public Object getInputSource()

从类复制的说明: JacksonParser

Method that can be used to get access to object that is used to access input being parsed; this is usually either InputStream or Reader, depending on what parser was constructed with. Note that returned value may be null in some cases; including case where parser implementation does not want to exposed raw source to caller. In cases where input has been decorated, object returned here is the decorated version; this allows some level of interaction between users of parser 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.

覆盖:

getInputSource 在类中 JacksonParser

close

public void close()
           throws IOException

从类复制的说明: JacksonParser

Closes the parser so that no further iteration or data access can be made; will also close the underlying input source if parser either owns the input source, or feature JacksonParser.Feature.AUTO_CLOSE_SOURCE is enabled. Whether parser owns the input source depends on factory method that was used to construct instance (so check JsonFactory for details, but the general idea is that if caller passes in closable resource (such as InputStream or Reader) parser does NOT own the source; but if it passes a reference (such as File or URL and creates stream or reader it does own them.

指定者:

close 在接口中 Closeable

指定者:

close 在接口中 AutoCloseable

指定者:

close 在类中 JacksonParser

抛出:

IOException

isClosed

public boolean isClosed()

从类复制的说明: JacksonParser

Method that can be called to determine whether this parser is closed or not. If it is closed, no new tokens can be retrieved by calling JacksonParser.nextToken() (and the underlying stream may be closed). Closing may be due to an explicit call to JacksonParser.close() or because parser has encountered end of input.

指定者:

isClosed 在类中 JacksonParser

getCurrentToken

public JsonToken getCurrentToken()

从类复制的说明: JacksonParser

Accessor to find which token parser currently points to, if any; null will be returned if none. If return value is non-null, data associated with the token is available via other accessor methods.

指定者:

getCurrentToken 在类中 JacksonParser

返回:

Type of the token this parser currently points to, if any: null before any tokens have been read, and after end-of-input has been encountered, as well as if the current token has been explicitly cleared.

hasCurrentToken

public boolean hasCurrentToken()

从类复制的说明: JacksonParser

Method for checking whether parser currently points to a token (and data for that token is available). Equivalent to check for parser.getCurrentToken() != null.

指定者:

hasCurrentToken 在类中 JacksonParser

返回:

True if the parser just returned a valid token via JacksonParser.nextToken(); false otherwise (parser was just constructed, encountered end-of-input and returned null from JacksonParser.nextToken(), or the token has been consumed)

getCurrentName

public String getCurrentName()
                      throws IOException,
                             JsonParseException

从类复制的说明: JacksonParser

Method that can be called to get the name associated with the current token: for JsonToken.FIELD_NAMEs it will be the same as what JacksonParser.getText() returns; for field values it will be preceding field name; and for others (array values, root-level values) null.

指定者:

getCurrentName 在类中 JacksonParser

抛出:

IOException

JsonParseException

getCurrentLocation

public JsonLocation getCurrentLocation()

从类复制的说明: JacksonParser

Method that returns location of the last processed character; usually for error reporting purposes.

指定者:

getCurrentLocation 在类中 JacksonParser

getParsingContext

public JsonStreamContext getParsingContext()

从类复制的说明: JacksonParser

Method that can be used to access current parsing context reader is in. There are 3 different types: root, array and object contexts, with slightly different available information. Contexts are hierarchically nested, and can be used for example for figuring out part of the input document that correspond to specific array or object (for highlighting purposes, or error reporting). Contexts can also be used for simple xpath-like matching of input, if so desired.

指定者:

getParsingContext 在类中 JacksonParser

clearCurrentToken

public void clearCurrentToken()

从类复制的说明: JacksonParser

Method called to "consume" the current token by effectively removing it so that JacksonParser.hasCurrentToken() returns false, and JacksonParser.getCurrentToken() null). Cleared token value can still be accessed by calling JacksonParser.getLastClearedToken() (if absolutely needed), but usually isn't.

Method was added to be used by the optional data binder, since it has to be able to consume last token used for binding (so that it will not be used again).

指定者:

clearCurrentToken 在类中 JacksonParser

getLastClearedToken

public JsonToken getLastClearedToken()

从类复制的说明: JacksonParser

Method that can be called to get the last token that was cleared using JacksonParser.clearCurrentToken(). This is not necessarily the latest token read. Will return null if no tokens have been cleared, or if parser has been closed.

指定者:

getLastClearedToken 在类中 JacksonParser

overrideCurrentName

public void overrideCurrentName(String name)

从类复制的说明: JacksonParser

Method that can be used to change what is considered to be the current (field) name. May be needed to support non-JSON data formats or unusual binding conventions; not needed for typical processing.

Note that use of this method should only be done as sort of last resort, as it is a work-around for regular operation.

指定者:

overrideCurrentName 在类中 JacksonParser

参数:

name - Name to use as the current name; may be null.

getText

public String getText()
               throws IOException,
                      JsonParseException

从类复制的说明: JacksonParser

Method for accessing textual representation of the current token; if no current token (before first call to JacksonParser.nextToken(), or after encountering end-of-input), returns null. Method can be called for any token type.

指定者:

getText 在类中 JacksonParser

抛出:

IOException

JsonParseException

hasTextCharacters

public boolean hasTextCharacters()

从类复制的说明: JacksonParser

Method that can be used to determine whether calling of JacksonParser.getTextCharacters() would be the most efficient way to access textual content for the event parser currently points to.

Default implementation simply returns false since only actual implementation class has knowledge of its internal buffering state. Implementations are strongly encouraged to properly override this method, to allow efficient copying of content by other code.

指定者:

hasTextCharacters 在类中 JacksonParser

返回:

True if parser currently has character array that can be efficiently returned via JacksonParser.getTextCharacters(); false means that it may or may not exist

getTextCharacters

public char[] getTextCharacters()
                         throws IOException,
                                JsonParseException

从类复制的说明: JacksonParser

Method similar to JacksonParser.getText(), but that will return underlying (unmodifiable) character array that contains textual value, instead of constructing a String object to contain this information. Note, however, that:

• Textual contents are not guaranteed to start at index 0 (rather, call JacksonParser.getTextOffset()) to know the actual offset
• Length of textual contents may be less than the length of returned buffer: call JacksonParser.getTextLength() for actual length of returned content.

Note that caller MUST NOT modify the returned character array in any way -- doing so may corrupt current parser state and render parser instance useless.

The only reason to call this method (over JacksonParser.getText()) is to avoid construction of a String object (which will make a copy of contents).

指定者:

getTextCharacters 在类中 JacksonParser

抛出:

IOException

JsonParseException

getTextLength

public int getTextLength()
                  throws IOException,
                         JsonParseException

从类复制的说明: JacksonParser

Accessor used with JacksonParser.getTextCharacters(), to know length of String stored in returned buffer.

指定者:

getTextLength 在类中 JacksonParser

返回:

抛出:

IOException

JsonParseException

getTextOffset

public int getTextOffset()
                  throws IOException,
                         JsonParseException

从类复制的说明: JacksonParser

Accessor used with JacksonParser.getTextCharacters(), to know offset of the first text content character within buffer.

指定者:

getTextOffset 在类中 JacksonParser

返回:

Offset of the first character within buffer returned by JacksonParser.getTextCharacters() that is part of textual content of the current token.

抛出:

IOException

                              throws IOException,
                                     JsonParseException

从类复制的说明: JacksonParser

Numeric accessor that can be called when the current token is of type JsonToken.VALUE_NUMBER_INT and it can not be used as a Java long primitive type due to its magnitude. It can also be called for JsonToken.VALUE_NUMBER_FLOAT; if so, it is equivalent to calling JacksonParser.getDecimalValue() and then constructing a BigInteger from that value.

指定者:

getBigIntegerValue 在类中 JacksonParser

抛出:

IOException

JsonParseException

getBooleanValue

public boolean getBooleanValue()
                        throws IOException,
                               JsonParseException

从类复制的说明: JacksonParser

Convenience accessor that can be called when the current token is JsonToken.VALUE_TRUE or JsonToken.VALUE_FALSE.

覆盖:

getBooleanValue 在类中 JacksonParser

抛出:

IOException

getByteValue

public byte getByteValue()
                  throws IOException,

从类复制的说明: JacksonParser

Numeric accessor that can be called when the current token is of type JsonToken.VALUE_NUMBER_INT and it can be expressed as a value of Java byte primitive type. It can also be called for JsonToken.VALUE_NUMBER_FLOAT; if so, it is equivalent to calling JacksonParser.getDoubleValue() and then casting; except for possible overflow/underflow exception.

Note: if the resulting integer value falls outside range of Java byte, a JsonParseException will be thrown to indicate numeric overflow/underflow.

覆盖:

从类复制的说明: JacksonParser

Generic number value accessor method that will work for all kinds of numeric values. It will return the optimal (simplest/smallest possible) wrapper object that can express the numeric value just parsed.

指定者:

getNumberValue 在类中 JacksonParser

抛出:

IOException

public Object getEmbeddedObject()
                         throws IOException,
                                JsonParseException

从类复制的说明: JacksonParser

Accessor that can be called if (and only if) the current token is JsonToken.VALUE_EMBEDDED_OBJECT. For other token types, null is returned.

Note: only some specialized parser implementations support embedding of objects (usually ones that are facades on top of non-streaming sources, such as object trees).

指定者:

getEmbeddedObject 在类中 JacksonParser

抛出:

JsonParseException

getBinaryValue

public byte[] getBinaryValue(Base64Variant b64variant)
                      throws IOException,
                             JsonParseException

从类复制的说明: JacksonParser

Method that can be used to read (and consume -- results may not be accessible using other methods after the call) base64-encoded binary data included in the current textual JSON value. It works similar to getting String value via JacksonParser.getText() and decoding result (except for decoding part), but should be significantly more performant.

Note that non-decoded textual contents of the current token are not guaranteed to be accessible after this method is called. Current implementation, for example, clears up textual content during decoding. Decoded binary content, however, will be retained until parser is advanced to the next event.

指定者:

getBinaryValue 在类中 JacksonParser

参数:

b64variant - Expected variant of base64 encoded content (see Base64Variants for definitions of "standard" variants).

返回:

Decoded binary data

抛出:

IOException

JsonParseException

getTokenLocation

public JsonLocation getTokenLocation()

从类复制的说明: JacksonParser

Method that return the starting location of the current token; that is, position of the first character from input that starts the current token.

nextToken

public JsonToken nextToken()
                    throws IOException,
                           JsonParseException

从类复制的说明: JacksonParser

Main iteration method, which will advance stream enough to determine type of the next token, if any. If none remaining (stream has no content other than possible white space before ending), null will be returned.

指定者:

nextToken 在类中 JacksonParser

返回:

Next token from the stream, if any found, or null to indicate end-of-input

抛出:

IOException

JsonParseException

nextValue

public JsonToken nextValue()
                    throws IOException,
                           JsonParseException

从类复制的说明: JacksonParser

Iteration method that will advance stream enough to determine type of the next token that is a value type (including JSON Array and Object start/end markers). Or put another way, nextToken() will be called once, and if JsonToken.FIELD_NAME is returned, another time to get the value for the field. Method is most useful for iterating over value entries of JSON objects; field name will still be available by calling JacksonParser.getCurrentName() when parser points to the value.

指定者:

nextValue 在类中 JacksonParser

返回:

Next non-field-name token from the stream, if any found, or null to indicate end-of-input (or, for non-blocking parsers, JsonToken.NOT_AVAILABLE if no tokens were available yet)

抛出:

IOException

JsonParseException

skipChildren

public JacksonParser skipChildren()
                           throws IOException,
                                  JsonParseException

从类复制的说明: JacksonParser

Method that will skip all child tokens of an array or object token that the parser currently points to, iff stream points to JsonToken.START_OBJECT or JsonToken.START_ARRAY. If not, it will do nothing. After skipping, stream will point to matching JsonToken.END_OBJECT or JsonToken.END_ARRAY (possibly skipping nested pairs of START/END OBJECT/ARRAY tokens as well as value tokens). The idea is that after calling this method, application will call JacksonParser.nextToken() to point to the next available token, if any.

指定者:

skipChildren 在类中 JacksonParser

抛出:

IOException

JsonParseException
