Method Detail

createProxy

public <T> T createProxy(Class<T> proxyType,
                         javax.inject.Provider<T> provider)
                  throws GenerationException

Description copied from interface: ProxyFactory

Creates a "virtual" proxy where method invocations on the proxy are delegated to the provided instance.

Type Parameters:

T - The proxy type

Parameters:

proxyType - The proxied class

provider - The provider of the proxied object

Returns:

The proxy

Throws:

GenerationException - If an error occurs creating the proxy

ProxyFactory.createProxy(Class, javax.inject.Provider)

createProxy

public <T> T createProxy(Class<T> proxyType,
                         ProxyHandler<T> handler)
                  throws GenerationException

Description copied from interface: ProxyFactory

Creates a proxy where method invocations on the proxy are passed to a single invoke method on the ProxyHandler.

Type Parameters:

T - The proxy type

Parameters:

proxyType - The proxied interface class

handler - The handler for the method invocation

Returns:

The proxy

Throws:

GenerationException - If an error occurs creating the proxy

ProxyFactory.createProxy(Class, org.proxy4j.core.ProxyHandler)

createProxy

public Object createProxy(Class<?>[] proxyInterfaces,
                          ProxyHandler<?> handler)
                   throws GenerationException

Description copied from interface: ProxyFactory

Creates a proxy that implements multiple interfaces where invocations on that proxy are passed to a single invoke method on the ProxyHandler. Equivalent to the traditional JDK proxy creation method: Proxy.newProxyInstance(ClassLoader, Class[], java.lang.reflect.InvocationHandler).

Parameters:

proxyInterfaces - The interfaces that the proxy class must implement

handler - The handler for the method invocation

Returns:

The proxy

Throws:

GenerationException - If an error occurs creating the proxy

See Also:

ProxyFactory.createProxy(Class[], org.proxy4j.core.ProxyHandler)

buildInterceptor

public <T> InterceptorBuilder<T> buildInterceptor(Class<T> proxyClass)

Description copied from interface: ProxyFactory

Creates a new builder for constructing an interceptor or "protection" proxy. The builder allows fine-grained customization of how the target's methods are intercepted.

Type Parameters:

T - The proxy type

Parameters:

proxyClass - The class of the proxy (and target)

Returns:

The builder

ProxyFactory.buildInterceptor(Class)
