Method for accessing textual representation of the current event; if no current event (before first call to nextToken() , or
after encountering end-of-input), returns null. |

JsonToken |
nextToken()
Main iteration method, which will advance stream enough to determine type of the next token, if any. |
void |
setCodec(ObjectCodec c)
Setter that allows defining ObjectCodec associated with this

public ObjectCodec getCodec()
JsonParser
ObjectCodec
associated with this
parser, if any. Codec is used by JsonParser.readValueAs(Class)
method (and its variants).
getCodec

public void setCodec(ObjectCodec c)
JsonParser
ObjectCodec
associated with this
parser, if any. Codec is used by JsonParser.readValueAs(Class)
method (and its variants).

protected boolean handleSignature(boolean consumeFirstByte, boolean throwException) throws IOException, JsonParseException

JsonParseException
protected static final SmileBufferRecycler<String> _smileBufferRecycler()
protected void _finishString() throws IOException, JsonParseException
_finishString
in class JsonParserBase
IOException
JsonParseException
public void close() throws IOException
JsonParser
JsonParser.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.
close
in interface Closeable
close
in class JsonParserBase
IOException
protected void _releaseBuffers() throws IOException
StreamBasedParserBase
StreamBasedParserBase._closeInput()
(for
example, when explicitly closing this reader instance), or

public JsonParser.NumberType getNumberType() throws IOException, JsonParseException
JsonParser

or
JsonToken.VALUE_NUMBER_FLOAT
, returns
one of JsonParser.NumberType
constants; otherwise returns null.
getNumberType
in class JsonNumericParserBase
IOException
JsonParseException
public String getText() throws IOException, JsonParseException
nextToken()
, or
after encountering end-of-input), returns null.
Method can be called for any event.
getText
in class JsonParserMinimalBase
IOException
JsonParseException
public char[] getTextCharacters() throws IOException, JsonParseException
JsonParser
JsonParser.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).
getTextCharacters
in class JsonParserMinimalBase
IOException
JsonParseException
public int getTextLength() throws IOException, JsonParseException
JsonParser
JsonParser.getTextCharacters()
, to know length
of String stored in returned buffer.
getTextLength
in class JsonParserMinimalBase
JsonParser.getTextCharacters()
that are part of
textual content of the current token.
IOException
JsonParseException
public int getTextOffset() throws IOException, JsonParseException
JsonParser
JsonParser.getTextCharacters()
, to know offset
of the first text content character within buffer.
getTextOffset
in class JsonParserMinimalBase
JsonParser.getTextCharacters()
that is part of
textual content of the current token.
IOException
JsonParseException
public byte[] getBinaryValue(Base64Variant b64variant) throws IOException, JsonParseException
JsonParser
JsonParser.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.
