    • getListener

      public ISchemaListener getListener()
      Get the schema change listener for this visitor.
      Returns:
      listener

    • countUse

      private void countUse(Object obj)
      Convenience method for incrementing a use count. If tracking of added references is enabled this also adds the referenced object to the list if it's a first-time reference.
      Parameters:
      obj - referenced object (null if none, ignored if a schema type)

    • addNonSingleton

      private void addNonSingleton(Object obj)
      Convenience method for recording a non-singleton reference.
      Parameters:
      obj - referenced object (null if none)

    • addReferenceClosure

      public void addReferenceClosure(AnnotatedBase comp)
      Add usage counts for the reference closure of a definition. This counts all references from the definition, then all references from the definitions referenced by the original definition, and so on until no new references are found. This method may be called repeatedly, with the final results representing the closure of the union of the specified definitions (or the union of the closure, since these are the same).
      Parameters:
      comp - definition to be processed

    • setNameRegister

      public void setNameRegister(NameRegister reg)
      Set the register to be used for resolving name references.
      Parameters:
      reg -

    • getUsageMap

      public ReferenceCountMap getUsageMap()
      Get map of reference counts per component.
      Returns:
      count map

    • getNonSingletonSet

      public Set getNonSingletonSet()
      Get the set of definitions referenced as optional or repeating.
      Returns:
      set

    • reset
