Comment(by gregboone):

 This will be a static method:


 {{{
     /// \brief
     /// Returns the list of class identifiers referenced by an expression
     ///
     /// \param functions
     /// Input a list of functions to be used when processing function type
 expressions
     ///
     /// \param originalClassDef
     /// Input the class definition applicable to the expression being
 evaluated
     ///
     /// \param expression
     /// Input the expression to be evaluated
     ///
     /// \param identifiers
     /// Output the IdentifierCollection that will be populated with the
 list of class
     /// identifiers referenced by the expression
     ///
     /// \return
     /// Returns nothing
     ///
     EXPRESSIONENGINE_API static void
 GetExpressionIdentifiers(FdoFunctionDefinitionCollection
 *functionDefinitions,
 FdoClassDefinition* originalClassDef,
 FdoExpression *expression,
 FdoIdentifierCollection* identifiers);
