Field Detail

• buf

  protected ByteBuffer buf

Constructor Detail

• ByteBufferOutputStream

  public ByteBufferOutputStream(int capacity)

• ByteBufferOutputStream

  public ByteBufferOutputStream(int capacity,
                        boolean useDirectByteBuffer)

• ByteBufferOutputStream

  public ByteBufferOutputStream(ByteBuffer bb)

  Parameters:

  bb - ByteBuffer to use. If too small, will be discarded and a new one allocated in its place; i.e. the passed in BB may NOT BE RETURNED!! Minimally it will be altered. SIDE EFFECT!! If you want to get the newly allocated ByteBuffer, you'll need to pick it up when done with this instance by calling getByteBuffer(). All this encapsulation violation is so we can recycle buffers rather than allocate each time; it can get expensive especially if the buffers are big doing allocations each time or having them undergo resizing because initial allocation was small.

  getByteBuffer()

Method Detail

• size

  public int size()

• getByteBuffer

  public ByteBuffer getByteBuffer()

  This flips the underlying BB so be sure to use it _last_!

  Returns:

  ByteBuffer
