Interface JoinPoint

  • All Known Subinterfaces:
    ProceedingJoinPoint
    public interface JoinPoint

    Provides reflective access to both the state available at a join point and static information about it. This information is available from the body of advice using the special form thisJoinPoint. The primary use of this reflective information is for tracing and logging applications. 

     aspect Logging {
     before(): within(com.bigboxco..*) && execution(public * *(..)) {
         System.err.println("entering: " + thisJoinPoint);
         System.err.println("  w/args: " + thisJoinPoint.getArgs());
         System.err.println("      at: " + thisJoinPoint.getSourceLocation());
     }
 }

    • Method Detail

      • toString

        java.lang.String toString()
        Overrides:
        toString in class java.lang.Object

      • toShortString

        java.lang.String toShortString()
        Returns an abbreviated string representation of the join point.

      • toLongString

        java.lang.String toLongString()
        Returns an extended string representation of the join point.

      • getThis

        java.lang.Object getThis()

        Returns the currently executing object. This will always be the same object as that matched by the this pointcut designator. Unless you specifically need this reflective access, you should use the this pointcut designator to get at this object for better static typing and performance.

        Returns null when there is no currently executing object available. This includes all join points that occur in a static context.

      • getTarget

        java.lang.Object getTarget()

        Returns the target object. This will always be the same object as that matched by the target pointcut designator. Unless you specifically need this reflective access, you should use the target pointcut designator to get at this object for better static typing and performance.

        Returns null when there is no target object.

      • getArgs

        java.lang.Object[] getArgs()

        Returns the arguments at this join point.

      • getSignature

        Signature getSignature()
        Returns the signature at the join point. getStaticPart().getSignature() returns the same object

      • getSourceLocation

        SourceLocation getSourceLocation()

        Returns the source location corresponding to the join point.

        If there is no source location available, returns null.

        Returns the SourceLocation of the defining class for default constructors.

        getStaticPart().getSourceLocation() returns the same object.

      • getKind

        java.lang.String getKind()
        Returns a String representing the kind of join point. This String is guaranteed to be interned. getStaticPart().getKind() returns the same object.

      • getStaticPart

        JoinPoint.StaticPart getStaticPart()
        Returns an object that encapsulates the static parts of this join point.
