## Detailed Description

Tool to scan a transient store branch that collects all the objects that belong to the same source (file).

By default, the list of entries is cached and the cache is cleared at every BeginEvent incident.

Properties:

  DataService (string): Name of the data service to use [EventDataSvc]

  Root (string): Path to the element from which to start the scan [root of the data service]

  ScanOnBeginEvent (bool): If the scan has to be started during the BeginEvent incident (true) or on demand (false, default)
