Constructor Detail

BufferPipeInputStream

public BufferPipeInputStream(BufferPipeInputStream.InputHandler inputHandler)

Construct a new instance. The given inputHandler will be invoked after each buffer is fully read and when the stream is closed.

Parameters:

inputHandler - the input events handler

Method Detail

push

public void push(ByteBuffer buffer)

Push a buffer into the queue. There is no mechanism to limit the number of pushed buffers; if such a mechanism is desired, it must be implemented externally, for example maybe using a Semaphore.

Parameters:

buffer - the buffer from which more data should be read

push

public void push(Pooled<ByteBuffer> pooledBuffer)

Push a buffer into the queue. There is no mechanism to limit the number of pushed buffers; if such a mechanism is desired, it must be implemented externally, for example maybe using a Semaphore.

Parameters:

pooledBuffer - the buffer from which more data should be read

pushException

public void pushException(IOException e)

Push an exception condition into the queue. After this method is called, no further buffers may be pushed into this instance.

Parameters:

e - the exception to push

pushEof

public void pushEof()

Push the EOF condition into the queue. After this method is called, no further buffers may be pushed into this instance.
