The Library Concept

Libraries help you to make your BPMN process executable. They contain predefined classes, interfaces, operations and parameters you can use during modeling by simple drag & drop.
Libraries are developed with the Builder. The Designer comes with a standard library which already provides all necessary Base Types.

Using libraries has several advantages for developers:

• You can provide additional data types and operations via libraries.
• You can reuse implementations you have already developed with the Builder.
• You can use libraries for modularization:
  • Implementations can be recycled in various processes via libraries.
    
  • Multiple developers can contribute to the same process implementation by working on different libraries.
• You can add features to the Designer, for example access to backend systems, via libraries.
• You can use different versions of the same library as the library administration allows ver

Library Usage in Designer

As libraries are developed with the Builder, you need to upload them to the Designer to make them accessible in your services.

In the Designer, you upload your libraries to a namespace. This is done in the Libraries section of the Designer administration. The uploaded libraries are then available in all services created in this namespace. How to upload your libraries to the Designer is explained in detail on page Administrating Libraries.

Once a library has been uploaded, you can add it to any service created in this namespace. There are two ways to do so:

• In the Explorer: Open the Libraries folder in your service and use the Manage Libraries button.
• In the BPMN Model: Use the Manage Libraries button in the Service panel.

The Service Panel

The libraries you have added to a service reside in the Service panel.

The documentation is displayed as a tooltip. For easier reading of longer documentation, you can click the icon to see the complete documentation in a pop-up window.: Image Added

Application Options

The panel shows all libraries available in this project. You can use the panel to manage your libraries and to use the contents of the libraries during modeling on the execution pane.

Managing Libraries

Using Library Content

You can drag & drop elements from the library panel to the execution pane.

Operations are dropped to the operations flow in the middle of the execution pane.

You can drag & drop classes, interfaces and parameters to the fields Persisted and Local:

• Persisted: The information is persisted and is therefore available in your whole BPMN model.
• Local: The information is only existing in the current operations flow.
