- All Implemented Interfaces:
- Closeable
- Direct Known Subclasses:
- Utf8NumericParser
public abstract class StreamBasedParserBase
- extends JsonNumericParserBase
This is a simple low-level input reader base class, used by
JSON parser. It is used when underlying input source is
a byte stream such as InputStream
.
The reason for sub-classing (over composition)
is due to need for direct access to low-level byte buffers
and positions.

Field Summary |
protected boolean |
_bufferRecyclable
Flag that indicates whether the input buffer is recycable (and
needs to be returned to recycler once we are done) or not. |
protected byte[] |
_inputBuffer
Current buffer from which data is read; generally data is read into
buffer from input source, but in some cases pre-loaded buffer
is handed to the parser. |
protected InputStream |
_inputStream
Input stream that can be used for reading more content, if one
in use. |

_inputStream
protected InputStream _inputStream
- Input stream that can be used for reading more content, if one
in use. May be null, if input comes just as a full buffer,
or if the stream has been closed.
_inputBuffer
protected byte[] _inputBuffer
- Current buffer from which data is read; generally data is read into
buffer from input source, but in some cases pre-loaded buffer
is handed to the parser.
_bufferRecyclable
protected boolean _bufferRecyclable
- Flag that indicates whether the input buffer is recycable (and
needs to be returned to recycler once we are done) or not.

loadMore
protected final boolean loadMore()
throws IOException
- Specified by:
loadMore
in class JsonParserBase
- Throws:
IOException
_closeInput
protected void _closeInput()
throws IOException
- Specified by:
_closeInput
in class JsonParserBase
- Throws:
IOException
_releaseBuffers
protected void _releaseBuffers()
throws IOException
- Method called to release internal buffers owned by the base
reader. This may be called along with
_closeInput()
(for
example, when explicitly closing this reader instance), or
separately (if need be).
- Overrides:
_releaseBuffers
in class JsonParserBase
- Throws:
IOException
