Method Detail

evaluate

java.lang.Object evaluate(java.lang.String expression)

Evaluates the specified value expression against the evaluator's defaul variable resolver.

invokeMethod(String, Object[]) should be used if the expression is a method expression.

Throws:

javax.el.PropertyNotFoundException - some implementations may throw a PropertyNotFoundException if one of the EL properties is not found.

evaluate

java.lang.Object evaluate(java.lang.String expression,
                          javax.servlet.jsp.el.VariableResolver variableResolver)

Evaluates the specified value expression against the specified variable resolver.

invokeMethod(String, Class[], Object[]) should be used if the expression is a method expression.

Throws:

javax.el.PropertyNotFoundException - some implementations may throw a PropertyNotFoundException if one of the EL properties is not found.

evaluateHandleNull

java.lang.Object evaluateHandleNull(java.lang.String expression)

Evaluates the specified value expression against the evaluator's defaul variable resolver.

invokeMethod(String, Object[]) should be used if the expression is a method expression.

Differs from evaluate in that it is guaranteed not to throw a PropertyNotFoundException for null properties.

evaluateHandleNull

java.lang.Object evaluateHandleNull(java.lang.String expression,
                                    javax.servlet.jsp.el.VariableResolver variableResolve)

Evaluates the specified value expression against the specified variable resolver.

invokeMethod(String, Class[], Object[]) should be used if the expression is a method expression.

Differs from evaluate in that it is guaranteed not to throw a PropertyNotFoundException for null properties.

setValue

void setValue(java.lang.String expression,
              java.lang.Object value)

Sets the value of the specified expression. The expression resolve to a JavaBean property.

setValue

void setValue(java.lang.String expression,
              java.lang.Object value,
              javax.servlet.jsp.el.VariableResolver variableResolver)

Sets the value of the specified expression. The expression resolve to a JavaBean property.

getVariableResolver

javax.servlet.jsp.el.VariableResolver getVariableResolver()

Get the default variable resolver to be used while resolving expressions with this evaluator.
