OdFdFieldEvaluatorLoader Class

Class Hierarchy

Syntax

C++

class OdFdFieldEvaluatorLoader : public OdRxObject;

File

FdField.h

Description

This class is used to load the evaluators required for evaluating fields.

Remarks

This class acts as the interface between the field framework and the applications that implement evaluators. An application that implements evaluators should derive from this class and register an object of this class with the field engine when the application is loaded. The registered loader is used by the engine to obtain the evaluator object. Only one loader object is required for an application and it can support multiple evaluators. The loader objects are maintained globally and are used by all open documents.
