in base64-encoded sections.

_finishToken()
Method called when decoding of a token has been started, but not yet completed due
to missing input; method is to continue decoding due to at least one more byte
being made available to decode.
|
protected JsonToken |
_finishTokenWithEOF()
Method similar to
_finishToken() , but called when no more input is
available, and end-of-input has been detected. |
protected JsonToken |
_reportErrorToken(String actualToken) |

void |
endOfInput()
Method that should be called after last chunk of data to parse has been fed
(with
feedInput in sub-class); can be called regardless of what NonBlockingInputFeeder.needMoreInput()
returns. |
void |
feedInput(byte[] buf,
int start,
int end)
Method that can be called to feed more data, if (and only if)
NonBlockingInputFeeder.needMoreInput() returns true. |
ByteArrayFeeder |
getNonBlockingInputFeeder()
Method that will either return a feeder instance (if parser uses
non-blocking, aka asynchronous access); or
null for
parsers that use blocking I/O. |
boolean |
needMoreInput()
Method called to check whether it is ok to feed more data: parser returns true
if it has no more content to parse (and it is ok to feed more); otherwise false
(and no data should yet be fed).
|
JsonToken |
nextToken()
Main iteration method, which will advance stream enough
to determine type of the next token, if any.
|
int |
releaseBuffered(OutputStream out)
Method that can be called to push back any content that
has been read but not consumed by the parser.
