Interface SCSActivity

All Known Subinterfaces:

SipSCSActivity

public interface SCSActivity

The Service Composition Selection Activity is the activity type that Service Composition Selection Events are fired on. All Service Composition Selection Events for a single call are fired on the same Service Composition Selection Activity.

The SIS uses the same SLEE activity object to represent both the Service Composition Selection Activity and Interceptor Activity for a given call. Therefore it is possible for SIS components and SLEE applications that use either activity to share state related to the call if required.

The SLEE activity representing the Service Composition Selection Activity for a call ends when control of the call terminates in the SIS.
