Method Detail

doRead

public int doRead(ApplicationBufferHandler handler)
           throws java.io.IOException

Description copied from interface: InputBuffer

Read from the input stream into the ByteBuffer provided by the ApplicationBufferHandler. IMPORTANT: the current model assumes that the protocol will 'own' the ByteBuffer and return a pointer to it.

Specified by:

doRead in interface InputBuffer

Parameters:

handler - ApplicationBufferHandler that provides the buffer to read data into.

Returns:

The number of bytes that have been added to the buffer or -1 for end of stream

Throws:

java.io.IOException - If an I/O error occurs reading from the input stream

available

public int available()

Description copied from interface: InputBuffer

Obtain an estimate of the number of bytes that can be read without blocking. Typically, this will be the number of available bytes known to be buffered.

Specified by:

available in interface InputBuffer

Returns:

The number of bytes that can be read without blocking
