Class ImplJava1Helper

java.lang.Object
  org.portico.impl.hla13.ImplJava1Helper

All Implemented Interfaces:

ISpecHelper

public class ImplJava1Helper
extends Object
implements ISpecHelper

This class helps provides helper methods to the DefaultJava1RTIAmbassador class and helps bridge the gap between the Portico compatibility layer and the HLA 1.3 Annex A interface. The basic thrust of this class (like all ISpecHelper implementations) is that it provides the necessary facilities to turn HLA-interface-specific code into Portico-clean, interface independant code.

To maintain the independence of Portico from any particular HLA interface specification, this is one of the *ONLY* classes that is allowed to have classes from the hla.rti namespace in it. All other classes should use the facilities provided by the org.portico.shared.compat package
