      public class ProxyFactory
      extends ProxyCreatorSupport

  Factory for AOP proxies for programmatic use, rather than via a bean factory. This class provides a simple way of obtaining and configuring AOP proxies in code.

- - ### Constructor Detail

    - #### ProxyFactory

          public ProxyFactory()

      Create a new ProxyFactory.

    - #### ProxyFactory

          public ProxyFactory(Object target)

      Create a new ProxyFactory.

      Will proxy all interfaces that the given target implements.

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

    - #### ProxyFactory

          public ProxyFactory(Class<?>... proxyInterfaces)

      Create a new ProxyFactory.

      No target, only interfaces. Must add interceptors.

      Parameters:
        `proxyInterfaces` - the interfaces that the proxy should implement

    - #### ProxyFactory

          public ProxyFactory(Class<?> proxyInterface,
                      Interceptor interceptor)

      Create a new ProxyFactory for the given interface and interceptor.

      Convenience method for creating a proxy for a single interceptor, assuming that the interceptor handles all calls itself rather than delegating to a target, like in the case of remoting proxies.

      Parameters:
        `proxyInterface` - the interface that the proxy should implement
        `interceptor` - the interceptor that the proxy should invoke

    - #### ProxyFactory

          public ProxyFactory(Class<?> proxyInterface,
                      TargetSource targetSource)

      Create a ProxyFactory for the specified `TargetSource`, making the proxy implement the specified interface.
      Parameters:
        `proxyInterface` - the interface that the proxy should implement
        `targetSource` - the TargetSource that the proxy should invoke

  - ### Method Detail

    - #### getProxy

          public Object 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 proxy object

    - #### getProxy

          public Object 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 (or `null` for the low-level proxy facility's default)
      Returns:
        the proxy object

    - #### getProxy

          public static <T> T getProxy(Class<T> proxyInterface,
                       Interceptor interceptor)

      Create a new proxy for the given interface and interceptor.

      Convenience method for creating a proxy for a single interceptor, assuming that the interceptor handles all calls itself rather than delegating to a target, like in the case of remoting proxies.

      Parameters:
        `proxyInterface` - the interface that the proxy should implement
        `interceptor` - the interceptor that the proxy should invoke
      Returns:
        the proxy object
      See Also:
        `ProxyFactory(Class, org.aopalliance.intercept.Interceptor)`

    - #### getProxy

          public static <T> T getProxy(Class<T> proxyInterface,
                       TargetSource targetSource)

      Create a proxy for the specified `TargetSource`, implementing the specified interface.
      Parameters:
        `proxyInterface` - the interface that the proxy should implement
        `targetSource` - the TargetSource that the proxy should invoke
      Returns:
        the proxy object
      See Also:
        `ProxyFactory(Class, org.springframework.aop.TargetSource)`

    - #### getProxy

          public static Object getProxy(TargetSource targetSource)

      Create a proxy for the specified `TargetSource` that extends the target class of the `TargetSource`.
      Parameters:
        `targetSource` - the TargetSource that the proxy should invoke
      Returns:
        the proxy object
