The diagram below illustrates the calling sequences for the APIs that are used to log in to the Process Engine and create a Process session, retrieve work objects, query queues, retrieve Step Processor information, and other workflow-related operations. The diagram includes the primary classes and methods, but does not include all APIs that may be used for workflow operations.

Note: Duplicate classes appear in the diagram for readability and have no programmatic significance.
