- - ### Constructor Detail

    - #### AspectJProxyFactory

          public AspectJProxyFactory()

      Create a new AspectJProxyFactory.

    - #### AspectJProxyFactory

          public AspectJProxyFactory(Object target)

      Create a new AspectJProxyFactory.

      Will proxy all interfaces that the given target implements.

      Parameters:
        `target` - the target object to be proxied

    - #### AspectJProxyFactory

          public AspectJProxyFactory(Class[] interfaces)

      Create a new `AspectJProxyFactory`. No target, only interfaces. Must add interceptors.

  - ### Method Detail

    - #### addAspect

          public void addAspect(Object aspectInstance)

      Add the supplied aspect instance to the chain. The type of the aspect instance supplied must be a singleton aspect. True singleton lifecycle is not honoured when using this method - the caller is responsible for managing the lifecycle of any aspects added in this way.
      Parameters:
        `aspectInstance` - the AspectJ aspect instance

    - #### addAspect

          public void addAspect(Class aspectClass)

      Add an aspect of the supplied type to the end of the advice chain.
      Parameters:
        `aspectClass` - the AspectJ aspect class

    - #### getProxy

          public <T> T getProxy()

      Create a new proxy according to the settings in this factory.

      Can be called repeatedly. Effect will vary if we've added or removed interfaces. Can add and remove interceptors.

      Uses a default class loader: Usually, the thread context class loader (if necessary for proxy creation).

      Returns:
        the new proxy

    - #### getProxy

          public <T> T getProxy(ClassLoader classLoader)

      Create a new proxy according to the settings in this factory.

      Can be called repeatedly. Effect will vary if we've added or removed interfaces. Can add and remove interceptors.

      Uses the given class loader (if necessary for proxy creation).

      Parameters:
        `classLoader` - the class loader to create the proxy with
      Returns:
        the new proxy
