Constructor	Description
InterceptionUtilities()	Creates the interception utilities.

Method Summary

Modifier and Type	Method	Description
InterceptableMethod	createInterceptableMethod(Class<? extends Interceptable> clazz, Class<? extends Interceptable> delegateClazz, Method method)	Creates an interceptable method.
Method	findDeclaredMethod(Class<?> clazz, Method method)	Finds the declared interface method for a given method signature. This usually indicates that the invocation handler is not servicing the expected interface. The default implementation just logs the fact that something is weird and returns the passed method.
Interceptor	findInterceptors(Class<?> clazz, Method method, Method implMethod)	Finds all interceptors of a method.
static InterceptionUtilities	getInstance()	The singleton.

Constructor Details

InterceptionUtilities

public InterceptionUtilities()

Creates the interception utilities.

Method Details

getInstance

public static InterceptionUtilities getInstance()

The singleton.

Returns:

the singleton

findInterceptors

public Interceptor findInterceptors(Class<?> clazz,
 Method method,
 Method implMethod)

Finds all interceptors of a method.

Parameters:

clazz - the interface which the interface the method is declared in extends

method - the interface method

implMethod - the implementing class method

Returns:

the head of interceptors, null if not intercepted

createInterceptableMethod

public InterceptableMethod createInterceptableMethod(Class<? extends Interceptable> clazz,
 Class<? extends Interceptable> delegateClazz,
 Method method)

Creates an interceptable method.

Finds the implementing method of the delegate and optional interceptors.

Parameters:

clazz - the topmost interceptable interface

delegateClazz - the delegate's class to invoke the method on

method - the interface's method to invoke

Returns:

the interceptable method

findDeclaredMethod

public Method findDeclaredMethod(Class<?> clazz,
 Method method)

Finds the declared interface method for a given method signature.
This usually indicates that the invocation handler is not servicing the expected interface.
The default implementation just logs the fact that something is weird and returns the passed method.

Parameters:

clazz - the top-level interface serviced by the invocation handler

method - the invoked interface method

Returns:

the effective interface method to scan for public interceptors
