Interface IAttributeAccessConnector

public interface IAttributeAccessConnector

This interface defines retrieving custom attributes for an item. The IAttributeAccessConnector interface should be implemented by all the Custom attribute connectors. This interface defines methods to retreive Attributes from different systems. Attributes names and the connector are specified in the Universal Worklist configuration (also known as Configuration XML).

IAttributeAccessConnector implementations can use any communication mechanism to connect to the systems and reteive the Items. For example: EJB call, JCO, Web Service etc

IAttributeAccessConnector implementations are expected to be stateless and hence thread safe.

Custom IAttributeAccessConnector implementation should be registered to IUWLService.
UWL ships four attribute access connectors by default. They are

1. UM : For retrieving Users attributes like firstName, LastName etc.
3. ABAP_BOR : For retrieving attributes from ABAP BOR repositoty.
5. WEBFLOW_CONTAINER : For retrieving attributes from work item container for Business Workflow items.
7. ALERT_CONTAINER : For retrieving attributes from Alerts container for alert items.
