All Implemented Interfaces:

Serializable

public class Invocation

extends Object

implements Serializable

This object is built to contain a call to a component within the component's facade. It is then passed through the interceptor chain to allow interceptors to handle the call appropriately.

Constructor Detail

Invocation

public Invocation(Object target,
                  Method method,
                  Object[] methodArguments,
                  Class[] methodSignature,
                  boolean isTargetFunctionalImplementation)

Constructs an invocation object

Parameters:

target - the Target object on which this method was intended to be called. Must be either the component's implementation or one of its configured decorators.

method - the method that intended

methodArguments - the arguments to the method

methodSignature - the signature of the method

isTargetFunctionalImplementation - true if this invocation's target is the component's functional implementation, false if it is one of the decorators.

Method Detail

getTarget

public Object getTarget()

Retrieves the target object.

Returns:

the target object

getMethod

public Method getMethod()

Gets the method being invoked.

Returns:

method being invoked

getMethodArguments

public Object[] getMethodArguments()

Returns the array of object parameters for the target method.

Returns:

array of object parameters for the target method

getMethodSignature

public Class[] getMethodSignature()

Returns the array of classes for the target method.

Returns:

array of classes for the target method

isTargetFunctionalImplementation

public boolean isTargetFunctionalImplementation()

Is the intended target the component's functional implementation. This is typically used by interceptors who provide special functionality for calls to the functional impelementation.

Returns:

true if the target is the functional impelementation
