astExport
-
Export an Object pointer to an outer context
- Description:
- This function exports an Object pointer from the current AST context
into the context that encloses the current one. This means that
the pointer will no longer be annulled when the current context
is ended (with astEnd), but only when the next outer context (if
any) ends.
- Synopsis:
- void astExport( AstObject
this )
- Parameters:
-
this
-
Object pointer to be exported.
- Class Applicability:
-
Object
-
This function applies to all Objects.
- Notes:
- It is only sensible to apply this function to pointers that
have been created within (or exported to) the current context
and have not been rendered exempt using astExempt.
Applying it to an unsuitable Object pointer has no effect.
