Class TCPEntity.Context

java.lang.Object
  TCPEntity.Context

Enclosing class:

TCPEntity

public class TCPEntity.Context
extends java.lang.Object

A Context is created by a TCPEntity and passed to its RDTProtocol during set up of the TCPEntity. The Context gives the RDTProtocol access to private data of the TCPEntity. After setUp() is invoked, the data accessed through the Context is not accessed except on the protocol thread so the access can be unsynchronized.

Constructor Summary

TCPEntity.Context()

Method Summary

Packet	createPacket() cntxt.createPacket() returns a new packet that only requires setting its identification number an sequence number befor use.
RDTTimer	createTimer() cntxt.createTimer() returns a new timer that only requires setting its packet before use.
java.lang.String	getName() cntxt.getName() returns the name of the TCPEntity that created this Context.
void	reassemble(int id) cntxt.reassemble(id) sends the segment id to the reassembler of this TCPEntity.
void	setAcceptingNewSegments(boolean ans) cntxt.setAcceptingNewSegments(ans) allows this TCPEntity to schedule new segment tasks if ans is true.
void	setPendingAcknowledgements(boolean pa) cntxt.setPendingAcknowledgements(pa) notifies this TCPEntity that its protocol has packets that have been sent but not yet acknowledged.
void	terminate() cntxt.terminate() terminates the execution of the thread created by this TCPEntity.
