Interface VariableResolver

  • @Deprecated
public interface VariableResolver
    Deprecated.
    As of JSP 2.1, replaced by jakarta.el.ELResolver

    This class is used to customize the way an ExpressionEvaluator resolves variable references at evaluation time. For example, instances of this class can implement their own variable lookup mechanisms, or introduce the notion of "implicit variables" which override any other variables. An instance of this class should be passed when evaluating an expression.

    An instance of this class includes the context against which resolution will happen

    Since:
    JSP 2.0
