Use case wrappers (old style)

Syntax

usecase {
  prewrappers = {
    prewrapper,
    ...
  }
  postwrappers = {
    postwrapper,
    ...
  }
}

Fabasoft app.ducx allows you to add a use case wrapper to an existing use case that is invoked whenever the wrapped use case is executed.

Note: Wrappers are only allowed if the software component has a 1.* domain ID (e.g. DUCXSAMP@1.1001).

Two types of use case wrappers are supported:

The prewrappers keyword is used to assign one or more prewrappers to an existing use case. Multiple entries must be separated by colons. A prewrapper is invoked before the wrapped use case is executed.
The postwrappers keyword is used to assign one or more postwrappers to an existing use case. Multiple entries must be separated by colons. A postwrapper is invoked after the wrapped use case has been executed successfully.

Note: A use case wrapper must be assigned the same prototype or parameter list as the use case to be wrapped by the use case wrapper.

Cloud profile note: The definition of use case wrappers is not allowed.

Example

usecases APPDUCXSAMPLE@200.200
{
import COOSYSTEM@1.1;

  VerifyContent(parameters as AttrSetPrototype) {
    variant Object {
      java = APPDUCXSAMPLE.Object.VerifyContent;
    }
  }

  override AttrContentSet {
    postwrappers = {
      VerifyContent
    }
}
}
