PM41492: Avoid forward declaration on Usage for Implementation

Rational Rhapsody 8.0
Rational Rhapsody 8.0.6

APAR status

• Closed as program error.

Error description

• In a model, on adding a ??Usage?? dependency from class B to
  class A, and setting it to 'Implementation' usage, should add a
  #include 'A.h' to the implementation file for class B. It does,
  however, it also adds a forward declaration of class A to the
  specification file of class B. This should not happen and it
  causes problems.Only Want the Usage dependency to generate the
  #include in the implementation file,And not to create a forward
  declaration.Unchecking the property
  'CG:Configuration:GenerateForwardDeclarations',which overrides
  the CG:Dependency:UsageType does not help. Neither the WA of
  Creating a new stereotype (NoForwardDec) applicable to 'Class'
  and deselecting the 'GenerateForwardDeclarations' property.
  Further applying the stereotype to any class to stop the
  redundant forward declarations, also dont help.Because, Its the
  use/include of a class that is causing the forward
  declaration,not the class itself.Also, the scenario of using
  class B by implementation/#include in one place and in another
  place using the same class B by forward reference.So cannot turn
  off forward reference for class B.

  ****************************************************************
  When Usage is set to Implementation, a forward declaration
  is still generated in the specification file.
  

Problem conclusion

• The property GenerateForwardDeclarations now exists under
  CPP_CG::Dependency. You can set the value of this property
  to False, and the forward declaration will not be generated
  for the dependency.
