Class Overview
This interface represents a generic runtime joinpoint (in the AOP terminology).
A runtime joinpoint is an event that occurs on a static
joinpoint (i.e. a location in a the program). For instance, an
invocation is the runtime joinpoint on a method (static joinpoint).
The static part of a given joinpoint can be generically retrieved
using the getStaticPart() method.
In the context of an interception framework, a runtime joinpoint is then the reification of an access to an accessible object (a method, a constructor, a field), i.e. the static part of the joinpoint. It is passed to the interceptors that are installed on the static joinpoint.

Public Methods
public abstract AccessibleObject getStaticPart ()
Returns the static part of this joinpoint.
The static part is an accessible object on which a chain of interceptors are installed.
public abstract Object getThis ()
Returns the object that holds the current joinpoint's static part.
For instance, the target object for an invocation.
Returns
- the object (can be null if the accessible object is static).
public abstract Object proceed ()
Proceeds to the next interceptor in the chain.
The implementation and the semantics of this method depends on the actual joinpoint type (see the children interfaces).
Returns
- see the children interfaces' proceed definition.
Throws
| Throwable | if the joinpoint throws an exception. |
