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).

Specified by:

getProxy in interface AopProxy

Returns:

the proxy object

See Also:

Thread.getContextClassLoader()

---

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).

Specified by:

getProxy in interface AopProxy

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 Object getProxy(Class 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 Object getProxy(Class 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
