public JavassistAspectPlugin()

Method Details

wrap

public <C extends CoreComponent> C wrap(C instance,
 Map<Method,List<Aspect>> joinPoints)

Creates a proxy reference for a component instance, applying the specified aspects at defined join points. The proxy wraps the provided component instance, intercepting method calls as defined by the join points and their associated aspects. This enables the implementation of cross-cutting concerns such as logging, security, or performance monitoring.

Specified by:

wrap in interface AspectPlugin

Type Parameters:

C - the type of the component, which must extend CoreComponent

Parameters:

instance - the component instance to be wrapped by the proxy

joinPoints - a map associating methods to lists of Aspect objects defining the interception logic

Returns:

a proxy reference implementing the same interface as the provided component instance

unwrap

public <C extends CoreComponent> C unwrap(C component)

Description copied from interface: AspectPlugin

Retrieves the original component instance from a proxy reference. This method unwraps the proxy to return the underlying component instance, removing any aspect-related interception logic. If the provided component is not a proxy, the original instance is returned unchanged.

Specified by:

unwrap in interface AspectPlugin

Type Parameters:

C - the type of the component, which must extend CoreComponent

Parameters:

component - the proxy or component instance to unwrap

Returns:

the underlying component instance
