The Library Concept

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 supports versioning.

Library Usage in Designer

In the Designer, you can create your own libraries, see page Creating a Library for details. If you want to use the libraries in a Designer service, you have to 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. To do so, open the service and go to the Libraries folder in the Service panel.

The Service Panel

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

	The Service panel gives you direct access to all libraries of your service, and thus to all of your predefined classes, interfaces, operations and parameters. Tip Open menu Libraries in the Designer administration to upload your own libraries. A library can contain the following elements: Icon Name Package Class Property Interface Operation Parameter To expand an element in the tree, click on . Useif you want to collapse a tree below an element.
	Each library element can have a documentation. Hover your mouse on an element in the libraries folder to see if documentation is available. This is indicated by the icon. 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:
	You can also copy & paste content from a library to the data model of your service: packages, classes, properties, operations and parameters - including their subelements. The implementation of a copied operation, however, will be empty.

In addition to imported libraries with predefined data types, you can use the provided Base Types, or you can create your own data model.
