Method Detail

processInputStream

public abstract void processInputStream(java.io.InputStream in,
                                        java.io.OutputStream out)
                                 throws java.io.IOException

Reads a single request from the InputStream, then writes back a single response.

Throws:

java.io.IOException

processMultipleInputs

public void processMultipleInputs(java.io.InputStream in,
                                  java.io.OutputStream out)
                           throws java.io.IOException

Processes multiple requests from the same stream.
As per the google suggestion for streaming multiple messages, this reads the length of the buffer, then reads exactly that many bytes and decodes it. It repeats until either 0 is read for the length or until EOF.
