Error description

• Summary:
  MISRA rule 10-1-1 not respected by Rhapsody code generator
  
  
  Description:
  The attachment contains a simple example with an interface
  (interface_2) that has
  a reception on event: event_1.
  
  In generated code (see file interface_2.h), there is:
  
  //## class interface_2
  
  class interface_2 : virtual public OMReactive { ...
  
  
  The MISRA rule 10-1-1 (Advisory) says: ' Classes should not be
  derived from virtual bases.'
  
  This relates also to rule 10-1-2: 'A base class shall only be
  declared virtual if it is used in a diamond hierarchy.'
  
  In the example, we are not in a diamond hierarchy.
  
  Diamond hierarchy is:
  
  class A {};
  
  class B: public virtual A {}; // Compliant - A is a common base
  for D
  class C: public virtual A {}; // Compliant - A is a common base
  for D
  class D: public B, C {};
  
  But following line is not a diamond hierarchy:
  
  class E: public virtual A {}; // Non-compliant

  MISRA rule 9-3-2 not respected raised with APAR ID: PM48174 on

  MISRA rule 10-1-1 not respected by Rhapsody code generator -
  classes are derived from virtual bases.
  

Problem conclusion

• To have the "virtual" keyword removed, you must change the
  value of the property
  CPP_CG::Framework::ReactiveBaseAsVirtual to False. This did
  not work previously but has been fixed in version 7.6.0.1.
