JsonParserInputStream 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.

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 and null token), default value of
null will be returned; no exceptions are thrown.getValueAsString in class ParserMinimalBaseIOExceptionpublic String getValueAsString(String defValue) throws IOException

getValueAsInt in class ParserMinimalBaseIOExceptionpublic char[] getTextCharacters()
throws IOException
JsonParserJsonParser.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:
JsonParser.getTextOffset()) to
know the actual offset
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).

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.

It is functionally equivalent to:

Because much of input has to be processed in any case, no partial parsing is done: all input text will be stored for further processing. However, actual numeric value conversion will be deferred, since it is usually the most complicated and costliest part of processing.
