Interface MessageStreamDecoder

public interface MessageStreamDecoder

Decodes a message stream into separate messages.

Method Summary

java.nio.ByteBuffer	destroy() Destroy this decoder, i.e.
int	getDataBytesDecoded() Get the number of (piece) data bytes decoded from the transport, from the last decode op.
int	getProtocolBytesDecoded() Get the number of protocol (overhead) bytes decoded from the transport, from the last decode op.
void	pauseDecoding() Pause message decoding.
int	performStreamDecode(Transport transport, int max_bytes) Decode message stream from the given transport.
Message[]	removeDecodedMessages() Get the messages decoded from the transport, if any, from the last decode op.
void	resumeDecoding() Resume message decoding.

Method Detail

performStreamDecode

int performStreamDecode(Transport transport,
                        int max_bytes)
                        throws java.io.IOException

Decode message stream from the given transport.

Parameters:

transport - to decode from

max_bytes - to decode/read from the stream

Returns:

number of bytes decoded

Throws:

java.io.IOException - on decoding error

removeDecodedMessages

Message[] removeDecodedMessages()

Get the messages decoded from the transport, if any, from the last decode op.

Returns:

decoded messages, or null if no new complete messages were decoded

getProtocolBytesDecoded

int getProtocolBytesDecoded()

Get the number of protocol (overhead) bytes decoded from the transport, from the last decode op.

Returns:

number of protocol bytes recevied

getDataBytesDecoded

int getDataBytesDecoded()

Get the number of (piece) data bytes decoded from the transport, from the last decode op.

Returns:

number of data bytes received

pauseDecoding

void pauseDecoding()

Pause message decoding.

resumeDecoding

void resumeDecoding()

Resume message decoding.

destroy

java.nio.ByteBuffer destroy()

Destroy this decoder, i.e. perform cleanup.

Returns:

any bytes already-read and still remaining within the decoder
