Fields Summary
private String
value_
Constructors Summary
public RequestEncodingTag()
Constructs a new RequestEncodingTag. As with TagSupport, subclasses should not provide other constructors and are expected to call the superclass constructor

        super();
        init();
Methods Summary
public intdoStartTag()


        // evaluate any expressions we were passed, once per invocation
        evaluateExpressions();

	// chain to the parent implementation
	return super.doStartTag();
private voidevaluateExpressions()

        /* 
         * Note: we don't check for type mismatches here; we assume
         * the expression evaluator will return the expected type
         * (by virtue of knowledge we give it about what that type is).
         * A ClassCastException here is truly unexpected, so we let it
         * propagate up.
