Method Detail

### afterConstructor

    public Object afterConstructor(Object[] args,
                                   Object instantiatedInstance)

  Description copied from interface: `ConstructorInterceptor`
  Executed after the constructor passing the args and the instantiated instance.

  Specified by:
    `afterConstructor` in interface `ConstructorInterceptor`
  Parameters:
    `args` - The arguments
    `instantiatedInstance` - The instantiated instance
  Returns:
    The instantiated or replaced instance

### beforeConstructor

    public Object beforeConstructor(Object[] args,
                                    InvocationCallback callback)

  Description copied from interface: `ConstructorInterceptor`
  Executed before the real constructor. The callback object should be marked if invokation of the real constructor should be performed.

  Specified by:
    `beforeConstructor` in interface `ConstructorInterceptor`
  Parameters:
    `args` - The constructor args
    `callback` - The callback object
  Returns:
    The instantiated object or null

### beforeInvoke

    public Object beforeInvoke(Object target,
                               String methodName,
                               Object[] arguments,
                               InvocationCallback callback)

  Description copied from interface: `Interceptor`
  This code is executed before the method is optionally called.

  Specified by:
    `beforeInvoke` in interface `Interceptor`
  Parameters:
    `target` - receiver object for the method call
    `methodName` - name of the method to call
    `arguments` - arguments to the method call
    `callback` - The callback object
  Returns:
    any arbitrary result that replaces the result of the original method call only if the callback object is marked relays this result.

### afterInvoke

    public Object afterInvoke(Object object,
                              String methodName,
                              Object[] arguments,
                              Object result)

  Description copied from interface: `Interceptor`
  This code is executed after the method is optionally called.

  Specified by:
    `afterInvoke` in interface `Interceptor`
  Parameters:
    `object` - receiver object for the called method
    `methodName` - name of the called method
    `arguments` - arguments to the called method
    `result` - result of the executed method call or result of beforeInvoke if method was not called
  Returns:
    any arbitrary result that can replace the result of the original method call. Typically, the result parameter is returned.

### beforeGet

    public Object beforeGet(Object object,
                            String property,
                            InvocationCallback callback)

  Description copied from interface: `PropertyAccessInterceptor`
  Intercepts a getXXX call and returns a result. The result is replaced by the real value if doGet() return false

  Specified by:
    `beforeGet` in interface `PropertyAccessInterceptor`
  Parameters:
    `object` - The target object
    `property` - The property to get
    `callback` - The callback object
  Returns:
    A value supplied by the interceptor

### beforeSet

    public void beforeSet(Object object,
                          String property,
                          Object newValue,
                          InvocationCallback callback)

  Description copied from interface: `PropertyAccessInterceptor`
  Intercepts a setXXX call.

  Specified by:
    `beforeSet` in interface `PropertyAccessInterceptor`
  Parameters:
    `object` - The target object
    `property` - The property to set
    `newValue` - The new value
    `callback` - The callback object
