virtual int proc ( ReferenceMaker *  rmaker )

pure virtual

This is the method called by system from ReferenceTarget::DoEnumDependentsImpl().

Parameters

rmaker

- A pointer to the reference maker

Returns

One of the following values:

• DEP_ENUM_CONTINUE: This continues the enumeration
• DEP_ENUM_HALT: This stops the enumeration.
• DEP_ENUM_SKIP: Reference Targets can have multiple Reference Makers (dependents). In certain instances when DoEnumDependents() is used to enumerate them you may not want to travel up all of the "branches". By returning DEP_ENUM_SKIP from this method you tell the enumerator to not enumerate the current Reference Maker's dependents but not to halt the enumeration completely.

Implemented in FindMAXWrapperEnum, and FindCustAttribOwnerDEP.

CoreExport bool CheckIfAndSetAsVisited

(

ReferenceMaker *

rmaker

)

This method sets and checks whether a ReferenceMaker was visited.

This method is used to check whether a ReferenceMaker was previously visited by this callback object, and registers it as having been visited if not. This is used to only call the proc on each ReferenceMaker once. If you override ReferenceTarget::EnumDependentsImp, you should use this method to process your instance only if it was not previously visited.

Parameters

rmaker

- A pointer to the reference maker

Returns

Returns true of the rmaker was previously visited, false if not.
