Field Detail

• _sourceRef

  protected final Object _sourceRef

  Reference to the source object, which can be used for displaying location information

• _encoding

  protected JsonEncoding _encoding

  Encoding used by the underlying stream, if known.

• _managedResource

  protected final boolean _managedResource

  Flag that indicates whether underlying input/output source/target object is fully managed by the owner of this context (parser or generator). If true, it is, and is to be closed by parser/generator; if false, calling application has to do closing (unless auto-closing feature is enabled for the parser/generator in question; in which case it acts like the owner).

• _bufferRecycler

  protected final BufferRecycler _bufferRecycler

  Recycler used for actual allocation/deallocation/reuse

• _readIOBuffer

  protected byte[] _readIOBuffer

  Reference to the allocated I/O buffer for low-level input reading, if any allocated.

• _writeEncodingBuffer

  protected byte[] _writeEncodingBuffer

  Reference to the allocated I/O buffer used for low-level encoding-related buffering.

• _base64Buffer

  protected byte[] _base64Buffer

  Reference to the buffer allocated for temporary use with base64 encoding or decoding.

• _tokenCBuffer

  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.

• _concatCBuffer

  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.

• _nameCopyBuffer

  protected char[] _nameCopyBuffer

  Reference temporary buffer Parser instances need if calling app decides it wants to access name via 'getTextCharacters' method. Regular text buffer can not be used as it may contain textual representation of the value token.

Constructor Detail

• IOContext

  public IOContext(BufferRecycler br,
                   Object sourceRef,
                   boolean managedResource)
