public class IOContext extends Object
NOTE: non-final since 2.4, to allow sub-classing.
Modifier and Type | Field and Description |
---|---|
protected byte[] |
_base64Buffer
Reference to the buffer allocated for temporary use with
base64 encoding or decoding.
|
protected BufferRecycler |
_bufferRecycler
Recycler used for actual allocation/deallocation/reuse
|
protected char[] |
_concatCBuffer
Reference to the buffer allocated for buffering it for
output, before being encoded: generally this means concatenating
output, then encoding when buffer fills up.
|
protected JsonEncoding |
_encoding
Encoding used by the underlying stream, if known.
|
protected boolean |
_managedResource
Flag that indicates whether underlying input/output source/target
object is fully managed by the owner of this context (parser or
generator).
|
protected char[] |
_nameCopyBuffer
Reference temporary buffer Parser instances need if calling
app decides it wants to access name via 'getTextCharacters' method.
|
protected byte[] |
_readIOBuffer
Reference to the allocated I/O buffer for low-level input reading,
if any allocated.
|
protected Object |
_sourceRef
Reference to the source object, which can be used for displaying
location information
|
protected char[] |
_tokenCBuffer
Reference to the buffer allocated for tokenization purposes,
in which character input is read, and from which it can be
further returned.
|
protected byte[] |
_writeEncodingBuffer
Reference to the allocated I/O buffer used for low-level
encoding-related buffering.
