Interface EvaluatorFactory

All Known Implementing Classes:
InputMappedFactory, MappedEvaluatorFactory, ReflectiveFactory, ResultMappedFactory
public interface EvaluatorFactory
A factory used to construct evaluators for ScalarValuedFunctions. A number of implementations are provided which cover common use cases.

An EvaluatorFactory is used as part of a function description to provide a mechanism for creating evaluators for associated function instances. Because descriptions are serialized within the framework, implementations of EvaluatorFactory must also be serializable as JSON.
