Interface Joinpoint
- All Known Subinterfaces:
ConstructorInvocation
,FieldAccess
,Invocation
,MethodInvocation
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.

Method Details
-
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.
-
getThis
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).
-
getStaticPart
AccessibleObject getStaticPart()Returns the static part of this joinpoint.The static part is an accessible object on which a chain of interceptors are installed.
