EvaluatorGroupCallAndMemoizeTResult, TParameter1, TParameter2 Method (EvaluatorGroupCallback2TResult, TParameter1, TParameter2, TParameter1, TParameter2)

Optimizes calls to a callback that is expected to be called multiple times so that future calls with the same parameters return a cached result rather than actually invoking the callback again. The first time this method is called with a particular set of parameters, the callback is invoked and the result is stored in the evaluator group. The second and successive times this method is called with the same parameters, the cached result is returned without invoking the callback.

Parameters

callback: Type: AGI.FoundationEvaluatorGroupCallback2TResult, TParameter1, TParameter2
The method to invoke. This method must not have side-effects.
parameter1: Type: TParameter1
The first parameter to the callback.
parameter2: Type: TParameter2
The second parameter to the callback.

Type Parameters

TResult: The type of result returned by the method.
TParameter1: The type of the first parameter to the callback.
TParameter2: The type of the second parameter to the callback.

Return Value

Type: TResult
The result of invoking the callback with the specified parameters.

Exceptions

Exception	Condition
ArgumentNullException	Thrown when callback is .
InvalidOperationException	The result of calling callback implemented IEvaluator. Use CreateEvaluatorTEvaluator(EvaluatorGroupCallback0TEvaluator) instead of this method when the return value is an evaluator.
