Interface VariableResolver

  • public interface VariableResolver
    This interface can be implement with a custom resolver and set onto the Evaluator class. It will then be used to resolve variables when they are replaced in an expression as it gets evaluated. Varaibles resolved by the resolved will override any varibles that exist in the variable map of an Evaluator instance.
