Field Detail

• BYTE_READ_IO_BUFFER

  public static final int BYTE_READ_IO_BUFFER

  Buffer used for reading byte-based input.

  Constant Field Values

• BYTE_WRITE_ENCODING_BUFFER

  public static final int BYTE_WRITE_ENCODING_BUFFER

  Buffer used for temporarily storing encoded content; used for example by UTF-8 encoding writer

  See Also:

  Constant Field Values

• BYTE_WRITE_CONCAT_BUFFER

  public static final int BYTE_WRITE_CONCAT_BUFFER

  Buffer used for temporarily concatenating output; used for example when requesting output as byte array.

  See Also:

  Constant Field Values

• BYTE_BASE64_CODEC_BUFFER

  public static final int BYTE_BASE64_CODEC_BUFFER

  Buffer used for concatenating binary data that is either being encoded as base64 output, or decoded from base64 input.

  Since:

  2.1

  Constant Field Values

• CHAR_TOKEN_BUFFER

  public static final int CHAR_TOKEN_BUFFER

  Buffer used as input buffer for tokenization for character-based parsers.

  See Also:

  Constant Field Values

• CHAR_CONCAT_BUFFER

  public static final int CHAR_CONCAT_BUFFER

  Buffer used by generators; for byte-backed generators for buffering of String values to output (before encoding into UTF-8), and for char-backed generators as actual concatenation buffer.

  See Also:

  Constant Field Values

• CHAR_TEXT_BUFFER

  public static final int CHAR_TEXT_BUFFER

  Used through TextBuffer: directly by parsers (to concatenate String values) and indirectly via SegmentedStringWriter when serializing (databind level ObjectMapper and ObjectWriter). In both cases used as segments (and not for whole value), but may result in retention of larger chunks for big content (long text values during parsing; bigger output documents for generation).

  See Also:

  Constant Field Values

• CHAR_NAME_COPY_BUFFER

  public static final int CHAR_NAME_COPY_BUFFER

  For parsers, temporary buffer into which char[] for names is copied when requested as such; for WriterBasedGenerator used for buffering during writeString(Reader) operation (not commonly used).

  See Also:

  Constant Field Values

• _byteBuffers

  protected final AtomicReferenceArray<byte[]> _byteBuffers

• _charBuffers

  protected final AtomicReferenceArray<char[]> _charBuffers

Constructor Detail

• BufferRecycler

  public BufferRecycler()

  Default constructor used for creating instances of this default implementation.

• BufferRecycler

  protected BufferRecycler(int bbCount,
                           int cbCount)

  Alternate constructor to be used by sub-classes, to allow customization of number of low-level buffers in use.

  Parameters:

  bbCount - Number of byte[] buffers to allocate

  cbCount - Number of char[] buffers to allocate

  Since:

  2.4
