Method Details
-
doRead
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.- 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
int available()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.- Returns:
- The number of bytes that can be read without blocking
