Class IrLAPContext  view IrLAPContext download IrLAPContext.java

java.lang.Object
  extended bycom.synchrona.jred.irlap.IrLAPContext
All Implemented Interfaces:
iIrLAPFramerListener
public class IrLAPContext
extends java.lang.Object
implements iIrLAPFramerListener

IrLAPContext offers services for the IrLAP states. Log messages mimic directives in the IrLAP specification, which helps in debuggering.
