Class AroundPrimitive

java.lang.Object
  aspoev.primitive.StaticPrimitive
      aspoev.primitive.RuntimePrimitive
          aspoev.primitive.AroundPrimitive

All Implemented Interfaces:

aspoev.Executable, MemberElement, pJ.jasmine.PRI, java.io.Serializable

public class AroundPrimitive

extends RuntimePrimitive

implements pJ.jasmine.PRI

This class is a piece of meta around advice. It has two parts, 'before proceed' and 'after proceed' advice. If the underlying join point is to be executed, the method 'proceed()' (with no arguments) must be called in the before proceed advice. The value returned from the 'around' advice must be stored in the variable 'proceed'. If this around advice is going to call 'proceed', it must be done in the 'beforeProceed' statement. The result can be referenced by the 'afterProceed' statement as the variable 'proceed'. An around primitive is essntially a Runtime Primitive extended to contain another Vejal block for post-proceed advice. Around primitives are declared in the command line environment as follows: around () { ... // Valid Vejal syntax for execution before 'proceed()' ... // ('proceed()' must come here, if at all) } { ... // Valid Vejal syntax for execution after 'proceed()' }
