Methods in com.pervasive.datarush.functions with parameters of type EvaluatorFactory

Modifier and Type	Method and Description
FunctionEvaluator	EvaluationContext.constructEvaluator(EvaluatorFactory factory, List<Object> arguments, ScalarSettable result) Creates an evaluator for a top-level expression, binding its output to the provided result buffer.
ScalarValued	EvaluationContext.constructSubexpressionEvaluation(EvaluatorFactory factory, List<Object> arguments, ScalarTokenType resultType) Creates an evaluation of a subexpression which can be used as input to the evaluator of the expression containing it.
static ScalarValuedFunction	ScalarFunctionDescriptor.define(String name, FunctionTyper typer, EvaluatorFactory factory, Object... args) Defines an instance of a function requiring complex logic for determining result type and/or checking function arguments, as well as needing to choose between possible evaluator implementations.
static ScalarValuedFunction	ScalarFunctionDescriptor.define(String name, ScalarTokenType resultType, EvaluatorFactory factory, Object... args) Defines an instance of a function returning a result of the specified type but needing to choose between possible evaluator implementations.
