Method Details

createProxy

@SafeVarargs
public static <T> T createProxy(InvocationHandler handler,
 Class<T>... interfaceTypes)

Creates a dynamic proxy instance that implements the specified interfaces and routes method calls to the provided InvocationHandler.

Type Parameters:

T - the type of the proxy being returned

Parameters:

handler - the InvocationHandler for handling method calls on the proxy instance

interfaceTypes - the array of interface classes that the proxy instance will implement

Returns:

a proxy instance that implements the specified interfaces and forwards method calls to the handler

Throws:

IllegalArgumentException - if the handler is null, no interfaces are provided, or one of the specified classes is not an interface

RuntimeException - if the proxy cannot be created due to classloader visibility issues

createProxyWithClassLoader

@SafeVarargs
public static <T> T createProxyWithClassLoader(ClassLoader classLoader,
 InvocationHandler handler,
 Class<T>... interfaceTypes)

Creates a dynamic proxy instance with the specified ClassLoader, handler, and interfaces. The proxy instance will implement the specified interfaces and route method calls to the provided InvocationHandler.

Type Parameters:

T - the type of the proxy being returned

Parameters:

classLoader - the ClassLoader used to define the proxy class

handler - the InvocationHandler for intercepting method calls on the proxy instance

interfaceTypes - the array of interface classes that the proxy instance will implement

Returns:

a proxy instance that implements the specified interfaces and forwards method calls to the handler

Throws:

IllegalArgumentException - if the classLoader is null, the handler is null, no interfaces are provided, or any of the specified classes is not an interface

RuntimeException - if the proxy cannot be created due to classLoader visibility issues
