getROAccessRepository

public ROAccessReportsRepository getROAccessRepository()

Description copied from interface: Repository

The ROAccessReportsRepository is implemented via the strategy pattern. Depending on the type of the repository, you will get a different implementation of this handle at runtime. The respective implementation will setup the data-structures used to log RO_ACCESS_REPORTS and ease the access to the stored information.

Returns:

a handle to the RO_ACCESS_REPORTS repository. if the implementation of the repository does not implement this functionality, it shall return null.
