Constructor Detail

Output

public Output(ByteBuffer dest)

Output

public Output(ByteBuffer dest,
              BiFunction<ByteBufferStreams.Output,Integer,ByteBuffer> onFull)

Create a ByteBuffer output stream. You provide a buffer.

Parameters:

dest - initial buffer (null allowed)

onFull - callback to invoke on full. The callback will be called with the ByteBufferStreams.Output object and the number of bytes of room needed, and must return a buffer capable of ingesting that many bytes. The prior buffer will simply be tossed away, so if you are going to grow the buffer in place, you need to copy data, or you can take the buffer and send it on it's way.

Method Detail

getBuffer

public ByteBuffer getBuffer()

Get the current working buffer for this stream.

Returns:

buffer
