getCodec
Description copied from class:JsonParser
Accessor forObjectCodec
associated with this parser, if any. Codec is used byJsonParser.readValueAs(Class)
method (and its variants).- Specified by:
getCodec
in classJsonParser
- Returns:
- Codec assigned to this parser, if any;
null
if none
-
setCodec
Description copied from class:JsonParser
Setter that allows definingObjectCodec
associated with this parser, if any. Codec is used byJsonParser.readValueAs(Class)
method (and its variants).- Specified by:
setCodec
in classJsonParser
- Parameters:
c
- Codec to assign, if any;null
if none
-
canParseAsync
public boolean canParseAsync()Description copied from class:JsonParser
Method that can be called to determine if this parser instance uses non-blocking ("asynchronous") input access for decoding or not. Access mode is determined by earlier calls viaJsonFactory
; it may not be changed after construction.If non-blocking decoding is (@code true}, it is possible to call
JsonParser.getNonBlockingInputFeeder()
to obtain object to use for feeding input; otherwise (false
returned) input is read by blocking- Overrides:
canParseAsync
in classJsonParser
- Returns:
- True if this is a non-blocking ("asynchronous") parser
-
getReadCapabilities
Description copied from class:JsonParser
Accessor for getting metadata on capabilities of this parser, based on underlying data format being read (directly or indirectly).- Overrides:
getReadCapabilities
in classJsonParser
- Returns:
- Set of read capabilities for content to read via this parser
-
symbolTableForTests
-
releaseBuffered
Description copied from class:JsonParser
Method that can be called to push back any content that has been read but not consumed by the parser. This is usually done after reading all content of interest using parser. Content is released by writing it to given stream if possible; if underlying input is byte-based it can released, if not (char-based) it can not.- Overrides:
releaseBuffered
in classJsonParser
- Parameters:
out
- OutputStream to which buffered, undecoded content is written to- Returns:
- -1 if the underlying content source is not byte based
(that is, input can not be sent to
OutputStream
; otherwise number of bytes released (0 if there was nothing to release) - Throws:
IOException
- if write to stream threw exception
-
_releaseBuffers
Description copied from class:ParserBase
Method called to release internal buffers owned by the base reader. This may be called along withParserBase._closeInput()
(for example, when explicitly closing this reader instance), or separately (if need be).- Overrides:
_releaseBuffers
in classParserBase
- Throws:
IOException
- Not thrown by base implementation but could be thrown by sub-classes
-
getInputSource
Description copied from class:JsonParser
Method that can be used to get access to object that is used to access input being parsed; this is usually eitherInputStream
orReader
, 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.
- Overrides:
getInputSource
in classJsonParser
- Returns:
- Input source this parser was configured with
-
_closeInput
- Specified by:
_closeInput
in classParserBase
- Throws:
IOException
-
hasTextCharacters
public boolean hasTextCharacters()Description copied from class:JsonParser
Method that can be used to determine whether calling ofJsonParser.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.
- Overrides:
hasTextCharacters
in classParserBase
- Returns:
- True if parser currently has character array that can
be efficiently returned via
JsonParser.getTextCharacters()
; false means that it may or may not exist
-
getCurrentLocation
Description copied from class:ParserBase
Method that returns location of the last processed character; usually for error reporting purposes- Overrides:
getCurrentLocation
in classParserBase
- Returns:
- Location of the last processed input unit (byte or character)
-
getTokenLocation
Description copied from class:ParserBase
Method that return the starting location of the current token; that is, position of the first character from input that starts the current token.- Overrides:
getTokenLocation
in classParserBase
- Returns:
- Starting location of the token parser currently points to
-
getText
Method for accessing textual representation of the current event; if no current event (before first call toParserMinimalBase.nextToken()
, or after encountering end-of-input), returns null. Method can be called for any event.- Specified by:
getText
in classParserMinimalBase
- Returns:
- Textual value associated with the current token (one returned
by
JsonParser.nextToken()
or other iteration methods) - Throws:
IOException
- for low-level read issues, orJsonParseException
for decoding problems
-
_getText2
-
getText
Description copied from class:JsonParser
Method to read the textual representation of the current token in chunks and pass it to the given Writer. Conceptually same as calling:writer.write(parser.getText());
but should typically be more efficient as longer content does need to be combined into a singleString
to return, and write can occur directly from intermediate buffers Jackson uses.- Overrides:
getText
in classJsonParser
- Parameters:
writer
- Writer to write textual content to- Returns:
- The number of characters written to the Writer
- Throws:
IOException
- for low-level read issues or writes using passedwriter
, orJsonParseException
for decoding problems
-
getValueAsString
Description copied from class:JsonParser
Method that will try to convert value of current token to aString
. JSON Strings map naturally; scalar values get converted to their textual representation. If representation can not be converted to a String value (including structured types like Objects and Arrays andnull
token), default value of null will be returned; no exceptions are thrown.- Overrides:
getValueAsString
in classParserMinimalBase
- Returns:
String
value current token is converted to, if possible;null
otherwise- Throws:
IOException
- for low-level read issues, orJsonParseException
for decoding problems
-
getValueAsString
Description copied from class:JsonParser
Method that will try to convert value of current token to aString
. JSON Strings map naturally; scalar values get converted to their textual representation. If representation can not be converted to a String value (including structured types like Objects and Arrays andnull
token), specified default value will be returned; no exceptions are thrown.- Overrides:
getValueAsString
in classParserMinimalBase
- Parameters:
defValue
- Default value to return if conversion toString
is not possible- Returns:
String
value current token is converted to, if possible;def
otherwise- Throws:
IOException
- for low-level read issues, orJsonParseException
for decoding problems
-
getTextCharacters
Description copied from class:JsonParser
Method similar toJsonParser.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
JsonParser.getTextOffset()
) to know the actual offset - Length of textual contents may be less than the
length of returned buffer: call
JsonParser.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
JsonParser.getText()
) is to avoid construction of a String object (which will make a copy of contents).- Specified by:
getTextCharacters
in classParserMinimalBase
- Returns:
- Buffer that contains the current textual value (but not necessarily at offset 0, and not necessarily until the end of buffer)
- Throws:
IOException
- for low-level read issues, orJsonParseException
for decoding problems
- Textual contents are not guaranteed to start at
index 0 (rather, call
-
getTextLength
Description copied from class:JsonParser
Accessor used withJsonParser.getTextCharacters()
, to know length of String stored in returned buffer.- Specified by:
getTextLength
in classParserMinimalBase
- Returns:
- Number of characters within buffer returned
by
JsonParser.getTextCharacters()
that are part of textual content of the current token. - Throws:
IOException
- for low-level read issues, orJsonParseException
for decoding problems
-
getTextOffset
Description copied from class:JsonParser
Accessor used withJsonParser.getTextCharacters()
, to know offset of the first text content character within buffer.- Specified by:
getTextOffset
in classParserMinimalBase
- Returns:
- Offset of the first character within buffer returned
by
JsonParser.getTextCharacters()
that is part of textual content of the current token. - Throws:
IOException
- for low-level read issues, orJsonParseException
for decoding problems
-
getBinaryValue
Description copied from class:JsonParser
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 viaJsonParser.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.
- Overrides:
getBinaryValue
in classParserBase
- Parameters:
b64variant
- Expected variant of base64 encoded content (seeBase64Variants
for definitions of "standard" variants).- Returns:
- Decoded binary data
- Throws:
IOException
- for low-level read issues, orJsonParseException
for decoding problems
-
readBinaryValue
Description copied from class:JsonParser
Similar toJsonParser.readBinaryValue(OutputStream)
but allows explicitly specifying base64 variant to use.- Overrides:
readBinaryValue
in classJsonParser
- Parameters:
b64variant
- base64 variant to useout
- Output stream to use for passing decoded binary data- Returns:
- Number of bytes that were decoded and written via
OutputStream
- Throws:
IOException
- for low-level read issues, orJsonParseException
for decoding problems
-
getEmbeddedObject
Description copied from class:JsonParser
Accessor that can be called if (and only if) the current token isJsonToken.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). One exception is access to binary content (whether via base64 encoding or not) which typically is accessible using this method, as well as
JsonParser.getBinaryValue()
.- Overrides:
getEmbeddedObject
in classJsonParser
- Returns:
- Embedded value (usually of "native" type supported by format)
for the current token, if any;
null otherwise
- Throws:
IOException
- for low-level read issues, orJsonParseException
for decoding problems
-
_startArrayScope
- Throws:
IOException
-
_startObjectScope
- Throws:
