Detailed 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. <group Other_Classes>

Member Function Documentation

virtual OdFdFieldEvaluator* OdFdFieldEvaluatorLoader::findEvaluator	(	OdDbField *	pField,
		OdString &	pszEvalId
	)

pure virtual

Finds an evaluator for a field that does not have an evaluator ID.

Parameters

pField	[in] Input field for which to find an evaluator
pszEvalId	[out] Output pointer to receive the evaluator ID

virtual OdFdFieldEvaluator* OdFdFieldEvaluatorLoader::getEvaluator ( const OdString & pszEvalId )

pure virtual

The field engine calls this method to get the evaluator using the evaluator ID and uses the evaluator to evaluate the field.

Parameters

pszEvalId [in] Input evaluator ID for which the evaluator is required

OdFdFieldEvaluatorLoader::ODRX_DECLARE_MEMBERS ( OdFdFieldEvaluatorLoader )
