class HVchannel : public rtHVchannel

Class that corresponds to a PHENIX HV channel

Inheritance:

Public Methods
inline int getChannelNb(): Returns the channel number
virtual int getPeakCurrent(double& dPeakCurrent): virtual function which is overloaded in the case of 1471 channels
virtual int getPeakTripCurrent(double& dPeakTripCurrent): virtual function which is overloaded in the case of 1471 channels
virtual int getRampTripEnable(bool& bRTE): virtual function which is overloaded in the case of 1471 channels
inline short getTripCount(): Returns the trip count of the module
virtual bool hasBulkSupply(): member function to find out whether this channel belongs to a module that is divided into bulk supplies
HVchannel( int channelNum, const char *Name, const char *Type, HVmodule *pMyModule ): Constructor for a named channel of a given type
inline short incTripCount(): Increments the trip count of the module
virtual bool is1471(): name member function to distinguish 1471 channels & the new properties they possess
virtual bool isBulkSupply(): name member function to distinguish 1469 bulk supplies from normal channels
inline short resetTripCount(): Sets the trip count of the module
virtual int setPeakTripCurrent(double dPeakTripCurrent): virtual function which is overloaded in the case of 1471 channels
virtual int setRampTripEnable(bool bRTE): virtual function which is overloaded in the case of 1471 channels
virtual ~HVchannel(): (virtual) Destructor [as it might be a 1469]

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 an interface, rtHVchannel, that allows to access HV channels in real time; the HVchannel object also possesses a member variable which points to the HVDatabaseSet which controls it.
MODIFICATIONS:

Added support for 1469s through inheritance CW Jan 29, 1999
Objectivity Update:
This file has been updated to support the new Objectivity Database scheme -- R. Roth
