Editing Assemblies

You can use assemblies in any place where you would use a simple appliance. Assemblies can be used where ever you would use a simple appliance. This allows you to reuse infrastructure without increasing the the complexity of the application.

For example, a specialist in database clustering can create a stock assembly for clustered database deployment and publish it in a catalog. Application integrators can then use this assembly in multiple applications, whenever they need database scalability and/or high availability, and without having to know how exactly the cluster is set up and operates.

This section describes elements and editing capabilities that are available only when editing assemblies that are not the application top-level assembly (main). The editing of an assembly is very much like editing and configuring application main.

You can create and edit an assembly class

  1. Drag the assembly template class from the New Singletons section of the catalog pane onto the canvas.
  2. Right-click the new assembly appliance shape and select Modify Boundary.
  3. Configure the boundary of the assembly class as you would for a simple class.
  4. Right-click the assembly appliance shape and select Modify Interior to edit the interior of the assembly.

    A canvas that contains shapes for the assembly as defined by the class boundary appears.

    Drag classes from a catalog or create new singleton classes as you would for editing the application main to create the infrastructure of the assembly.

    To move around the assembly terminals, you need to click within the gray area on the terminal shape to select it and then drag it to the desired position on the canvas.

  5. Configure the assembly subordinate instances.
  6. Click Save to save your changes.
  7. After testing the assembly, move it to a catalog by clicking the assembly class shape and dragging it to the appropriate catalog as you would do for a simple class.
