GetReferenceTypes() public method

Provides the possible references types for this expression (used in semantic analysis)
public GetReferenceTypes ( INamable instance, BaseFilter expectation, bool last ) : DataDictionary.Interpreter.ReturnValue
instance INamable the reference instance on which this element should analysed
expectation BaseFilter Indicates the kind of element we are looking for
last bool indicates that this is the last element in a dereference chain
return DataDictionary.Interpreter.ReturnValue
