Documentation

Class that corresponds to a PHENIX HV channel. This class is used to access a PHENIX HV channels in real time as well as in the databse, i.e. the individual HV channels that are controlled by EPICS or stored in objectivity. Therefore HVchannel inherits from two interfaces: 1. from the object rtHVchannel that allows to access HV channels in real time, 2. from the object dbHVinterface from which it inherits a pointer to the database. This pointer is used to resolve the ooHandle( dbHVchannel ) which is the handle to the persistent object.
Note: Currently we only support 1461Nmod104 modules and will have to add the others later.
MODIFICATIONS:
Added support for 1469s through inheritance CW Jan 29, 1999
