Detailed Description

A cluster of FMS towers.

This is an elaborated version of the simple StFmsCluster class, storing extra information needed during the clustering process.

The StFmsTower objects in its towers() list are not owned by the StFmsTowerCluster, so those towers must have a longer lifetime than it. The user must also take responsibility for deleting them if they are dynamically allocated.

explicit

Constructor.

Initialise with a dynamically allocated StFmsCluster. The StFmsTowerCluster owns the StFmsCluster until the release() method is called, after which the StFmsTowerCluster no longer references a cluster and should not be used any longer.
