Method Detail

getMethodInfo

public javax.el.MethodInfo getMethodInfo(javax.el.ELContext context)
                                  throws java.lang.NullPointerException,
                                         javax.el.PropertyNotFoundException,
                                         javax.el.MethodNotFoundException,
                                         javax.el.ELException

Specified by:

getMethodInfo in class javax.el.MethodExpression

Parameters:

context - The EL context for this evaluation

Returns:

Information about the method that this expression resolves to

Throws:

java.lang.NullPointerException - If the supplied context is null

javax.el.PropertyNotFoundException - If a property/variable resolution failed because no match was found or a match was found but was not readable

javax.el.MethodNotFoundException - If no matching method can be found

javax.el.ELException - Wraps any exception throw whilst resolving the property

invoke

public java.lang.Object invoke(javax.el.ELContext context,
                               java.lang.Object[] params)
                        throws java.lang.NullPointerException,
                               javax.el.PropertyNotFoundException,
                               javax.el.MethodNotFoundException,
                               javax.el.ELException

Specified by:

invoke in class javax.el.MethodExpression

Parameters:

context - The EL context for this evaluation

params - The parameters with which to invoke this method expression

Returns:

The result of invoking this method expression

Throws:

java.lang.NullPointerException - If the supplied context is null

javax.el.PropertyNotFoundException - If a property/variable resolution failed because no match was found or a match was found but was not readable

javax.el.MethodNotFoundException - If no matching method can be found

javax.el.ELException - Wraps any exception throw whilst resolving the property or coercion of the result to the expected return type fails
