doRead
public int doRead(ApplicationBufferHandler handler) throws IOException
Description copied from interface:InputBufferRead 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:
doReadin interfaceInputBuffer- 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:
IOException- If an I/O error occurs reading from the input stream
-
available
public int available()
Description copied from interface:InputBufferObtain 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:
availablein interfaceInputBuffer- Returns:
- The number of bytes that can be read without blocking
