Examples of javax.servlet.jsp.el.ExpressionEvaluator.evaluate()

javax.servlet.jsp.el.ExpressionEvaluator.evaluate()
Evaluates an expression. This method may perform some syntactic validation and, if so, it should raise an ELParseException error if it encounters syntactic errors. EL evaluation errors should cause an ELException to be raised. @param expression The expression to be evaluated. @param expectedType The expected type of the result of the evaluation @param vResolver A VariableResolver instance that can be used at runtime to resolve the name of implicit objects into Objects. @param fMapper A FunctionMapper to resolve functions found in the expression. It can be null, in which case no functions are supported for this invocation. @return The result of the expression evaluation. @exception ELException Thrown if the expression evaluation failed.
