public class NonBlockingJsonParser extends NonBlockingUtf8JsonParserBase implements ByteArrayFeeder
Non-blocking parser implementation for JSON content that takes its input viabyte[]
passed.NOTE: only supports parsing of UTF-8 encoded content (and 7-bit US-ASCII since it is strict subset of UTF-8): other encodings are not supported.

getNonBlockingInputFeeder
public ByteArrayFeeder getNonBlockingInputFeeder()
Description copied from class:JsonParser
Method that will either return a feeder instance (if parser uses non-blocking, aka asynchronous access); ornull
for parsers that use blocking I/O.- Overrides:
getNonBlockingInputFeeder
in classJsonParser
- Returns:
- Input feeder to use with non-blocking (async) parsing
-
feedInput
public void feedInput(byte[] buf, int start, int end) throws java.io.IOException
Description copied from interface:ByteArrayFeeder
Method that can be called to feed more data, if (and only if)NonBlockingInputFeeder.needMoreInput()
returns true.- Specified by:
feedInput
in interfaceByteArrayFeeder
- Parameters:
buf
- Byte array that contains data to feed: caller must ensure data remains stable until it is fully processed (which is true whenNonBlockingInputFeeder.needMoreInput()
returns true)start
- Offset within array where input data to process startsend
- Offset after last byte contained in the input array- Throws:
java.io.IOException
- 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)
-
releaseBuffered
public int releaseBuffered(java.io.OutputStream out) throws java.io.IOException
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.- Specified by:
releaseBuffered
in classNonBlockingJsonParserBase
- 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:
java.io.IOException
- if write to stream threw exception
