@Deprecated public abstract class StreamBasedParserBase
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.

protected boolean |
_bufferRecyclable
Deprecated. 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
Deprecated. 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
Deprecated. Input stream that can be used for reading more content, if one in use. |

Note that returned value may be null in some cases; including
case where parser implementation does not want to exposed raw
source to caller.
In cases where input has been decorated, object returned here
is the decorated version; this allows some level of interaction
between users of parser and decorator object.
In general use of this accessor should be considered as "last effort", i.e. only used if no other mechanism is applicable.
