Member Function Documentation

virtual NamedString* getField ( ObjList stack,
const String name,
GenObject context 
) const [virtual]

Get a pointer to a field in extender

Parameters:
stackEvaluation stack in use
nameName of the field to retrieve
contextPointer to arbitrary object passed from evaluation methods
Returns:
Pointer to field, NULL if not present

Reimplemented in ScriptContext.

virtual bool hasField ( ObjList stack,
const String name,
GenObject context 
) const [virtual]

Check if a certain field is assigned in extender

Parameters:
stackEvaluation stack in use
nameName of the field to test
contextPointer to arbitrary object passed from evaluation methods
Returns:
True if the field is present

Reimplemented in ScriptContext.

virtual RefObject* refObj ( ) [virtual]

Retrieve the reference counted object owning this interface

Returns:
Pointer to object owning the extender, NULL if no ownership

Reimplemented in ScriptContext.

virtual bool runAssign ( ObjList stack,
const ExpOperation oper,
GenObject context 
) [virtual]

Try to assign a value to a single field

Parameters:
stackEvaluation stack in use
operField to assign to, contains the field name and new value
contextPointer to arbitrary object passed from evaluation methods
Returns:
True if assignment succeeded

Reimplemented in JsObject, and ScriptContext.

virtual bool runField ( ObjList stack,
const ExpOperation oper,
GenObject context 
) [virtual]

Try to evaluate a single field

Parameters:
stackEvaluation stack in use, field value must be pushed on it
operField to evaluate
contextPointer to arbitrary object passed from evaluation methods
Returns:
True if evaluation succeeded

Reimplemented in JsObject, and ScriptContext.

virtual bool runFunction ( ObjList stack,
const ExpOperation oper,
GenObject context 
) [virtual]

Try to evaluate a single function

Parameters:
stackEvaluation stack in use, parameters are popped off this stack and results are pushed back on stack
operFunction to evaluate
contextPointer to arbitrary object passed from evaluation methods
Returns:
True if evaluation succeeded

Reimplemented in JsObject, and ScriptContext.
