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.
