Method Detail

createProxy

public <T> T createProxy(Invoker invoker,
                         Class<?>... types)

Create a new proxy instance.

Note: If any type the proxy instance must fulfill are all interfaces, the factory will currently create a proxy based on the JDK.

Type Parameters:

T - The proxy's type.

Parameters:

invoker - the invocation handler.

types - the types the proxy must emulate.

Returns:

the new proxy instance.

canProxy

public boolean canProxy(Class<?> type)

Description copied from interface: ProxyFactory

Test if the ProxyFactory implementation is capable of creating a proxy instance for the given type.

Parameters:

type - the type to create a proxy instance for.

Returns:

true if the type is supported.

isProxyClass

public boolean isProxyClass(Class<?> type)

Description copied from interface: ProxyFactory

Test if the given type is a proxy class.

Parameters:

type - the type to examine.

Returns:

true if the given type is a proxy class.

getInvoker

public Invoker getInvoker(Object proxy)

Retrieve the invocation handler of the proxy. The implementation of this method relies on the implementation of the derived factory to add the interface InvokerReference to every proxy instance.

Specified by:

getInvoker in interface ProxyFactory

Parameters:

proxy - the proxy instance.

Returns:

the Invoker instance acting as invocation handler.
