firstBuffer

private DetectorStreamBufferImpl firstBuffer

The first buffer of the chain.

Constructor Detail

ProcessableDetectorStream

public ProcessableDetectorStream(Map<String,Object> mutableMetadata,
                                 ByteArrayPool byteArrayPool)

The constructor.
ATTENTION:
You have to call initialize(AbstractDetectorStreamProvider, DetectorStreamProcessor) after super-call in subclass-constructor.

Parameters:

mutableMetadata - is the initial mutable metadata.

byteArrayPool - is used to pool byte[]-buffers.

Method Detail

initialize

public void initialize(AbstractDetectorStreamProvider provider,
                       DetectorStreamProcessor lastProcessor)

This method initializes this class. It has to be called to complete the construction.

Parameters:

provider - is the DetectorStreamProvider creating this instance.

lastProcessor - is the last DetectorStreamProcessor of the chain (the data-receiver).

processInternal

public void processInternal(ByteArray buffer,
                            boolean eos)
                     throws IOException

Parameters:

buffer - is the next part of the streamed data.

eos - - true if the end of the stream has been reached and the given buffer has to be

Throws:

IOException - in case of an Input/Output error. Should only be used internally.

DetectorStreamProcessor.process(net.sf.mmm.util.io.api.spi.DetectorStreamBuffer, Map, boolean)

getByteArrayPool

protected ByteArrayPool getByteArrayPool()

This method gets a pool used to manage byte-arrays.

Returns:

the ByteArrayPool instance.
