Method Detail

readByteBufferFromHttp

public static ByteBuffer readByteBufferFromHttp(InputStream is)
                                         throws IOException

Throws:

IOException

postprocessBufferRead

public ByteBuffer postprocessBufferRead(ByteBuffer data)
                                 throws IOException

Description copied from interface: BufferTransformer

implementers can transform data available read from the socket. Any data left in the socketData argument will be used in subsequent NIOJICPConnection.readPacket() calls.

Specified by:

postprocessBufferRead in interface BufferTransformer

Returns:

a buffer containing the transformed data

Throws:

IOException - will be handled by the BEManagementService and if applicable NIOMediator

preprocessBufferToWrite

public ByteBuffer preprocessBufferToWrite(ByteBuffer dataToSend)
                                   throws IOException

Description copied from interface: BufferTransformer

implementers can transform the bytes before they are sent. When data in the dataToSend argument are left a IOException will be thrown by NIOJICPConnection.writePacket(jade.imtp.leap.JICP.JICPPacket).

Specified by:

preprocessBufferToWrite in interface BufferTransformer

Returns:

the ByteBuffer to send

Throws:

IOException - will be handled by the BEManagementService and if applicable NIOMediator

needSocketData

public boolean needSocketData()
