Doc from tools.jackson.core.async.NonBlockingInputFeeder.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 needMoreInput returns. After calling this method, no more data can be fed; and parser assumes no more data will be available.

Implements tools.jackson.core.async.ByteArrayFeeder.feedInput.

Doc from tools.jackson.core.async.ByteArrayFeeder.feedInput.

Method that can be called to feed more data, if (and only if) needMoreInput returns true.

Annotations

@Override

Exceptions

JacksonException:: if the state is such that this method should not be called (has not yet consumed existing input data, or has been marked as closed)

needMoreInput

back to summary

public final boolean needMoreInput()

Implements tools.jackson.core.async.NonBlockingInputFeeder.needMoreInput.

Doc from tools.jackson.core.async.NonBlockingInputFeeder.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).

Annotations

@Override

nextToken

back to summary

public JsonToken nextToken() throws JacksonException

Implements abstract tools.jackson.core.JsonParser.nextToken.

Doc from tools.jackson.core.JsonParser.nextToken.

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.

Annotations

@Override

Exceptions

JacksonException:: for low-level read issues

nonBlockingInputFeeder back to summary

public ByteArrayFeeder nonBlockingInputFeeder()

Overrides tools.jackson.core.JsonParser.nonBlockingInputFeeder.

Doc from tools.jackson.core.JsonParser.nonBlockingInputFeeder.

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.

@Override

releaseBuffered

back to summary

public int releaseBuffered(OutputStream out) throws JacksonException

Implements abstract tools.jackson.dataformat.smile.async.NonBlockingParserBase.releaseBuffered.

Doc from tools.jackson.core.JsonParser.releaseBuffered.

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 cannot.

JacksonException:: if write to stream threw exception
