Method Detail

create

public static org.aopalliance.intercept.MethodInvocation create(Object object,
                                                                String methodName,
                                                                Object... args)

Generates a MethodInvocation for specified methodName on the passed object, using the args to locate the method.

Parameters:

object - the object that will be used to find the relevant Method

methodName - the name of the method to find

args - arguments that are required as part of the method signature (can be empty)

Returns:

a MethodInvocation, or null if there was a problem

createFromClass

public static org.aopalliance.intercept.MethodInvocation createFromClass(Class<?> clazz,
                                                                         String methodName)

Generates a MethodInvocation for the specified methodName on the passed class. If a method with this name, taking no arguments does not exist, it will check through the declared methods on the class, until one is found matching the supplied name. If more than one method name matches, an IllegalArgumentException will be raised.

Parameters:

clazz - the class of object that will be used to find the relevant Method

methodName - the name of the method to find

Returns:

a MethodInvocation, or null if there was a problem

createFromClass

public static org.aopalliance.intercept.MethodInvocation createFromClass(Object targetObject,
                                                                         Class<?> clazz,
                                                                         String methodName,
                                                                         Class<?>[] classArgs,
                                                                         Object[] args)

Generates a MethodInvocation for specified methodName on the passed class, using the args to locate the method.

Parameters:

targetObject - the object being invoked

clazz - the class of object that will be used to find the relevant Method

methodName - the name of the method to find

classArgs - arguments that are required to locate the relevant method signature

args - the actual arguments that should be passed to SimpleMethodInvocation

Returns:

a MethodInvocation, or null if there was a problem
