Method Detail

handleRead

public org.glassfish.grizzly.filterchain.NextAction handleRead(org.glassfish.grizzly.filterchain.FilterChainContext ctx)
                                                        throws IOException

The method is called once we have received a single String line. Filter check if it's MultiLinePacket terminating line, if yes - we assume MultiLinePacket completed and pass control to a next Filter in a chain. If it's not a terminating line - we add another string line to a MultiLinePacket and stop the request processing until more strings will get available.
