Class ExpressionEvaluator

java.lang.Object
  org.odata4j.producer.ExpressionEvaluator

public class ExpressionEvaluator
extends Object

Evaluate an $filter expression. The VariableResolver you attach to the evaluator determines the context for evaluation. The VariableResolver must supply actual values for all EntitySimpleProperties referenced in the $filter.

Note: this used to be class InMemoryEvaluation, I just factored out/de-coupled the VariableResolver to make it reusable.
