All Implemented Interfaces:

StreamAlgorithm<SocketChannel>

public final class StateMachineAlgorithm
extends StreamAlgorithmBase

Predict if the NIO channel has been fully read or not. This lagorithm will first search for the content-length header, and use that value to determine if the bytes has been fully read or not. If the content-length isn't included, it will search for the end of the HTTP stream, which is a '\r\n'

Method Detail

parse

public boolean parse(ByteBuffer byteBuffer)

Parse the ByteBuffer and try to determine if the bytes stream has been fully read from the SocketChannel. Drain the SocketChannel and determine if the request bytes has been fully read. For POST method, parse the bytes and seek for the content-type header to determine the length of the request bytes.

Specified by:

parse in interface StreamAlgorithm<SocketChannel>

Specified by:

parse in class StreamAlgorithmBase

Returns:

true if we need to call back the SelectorThread This occurs when the stream doesn't contains all the request bytes. false if the stream contains all request bytes.

getHandler

public Interceptor getHandler()

Return the Interceptor used by this algorithm.

recycle

public void recycle()

Recycle this object.

Specified by:

recycle in interface StreamAlgorithm<SocketChannel>

Overrides:

recycle in class StreamAlgorithmBase
