      Description copied from class: `Expression`
      Evaluates an expression that was previously prepared. In some implementations preparing an expression involves full syntactic validation, but others may not do so. Evaluating the expression may raise an ELParseException as well as other ELExceptions due to run-time evaluation.
      Specified by:
        `evaluate` in class `Expression`
      Parameters:
        `vResolver` - A VariableResolver instance that can be used at runtime to resolve the name of implicit objects into Objects.
      Returns:
        The result of the expression evaluation.
      Throws:
        `ELException` - Thrown if the expression evaluation failed.
