Package OCSEPICS

Interface Summary

CAEventListener

This interface will be used to inform a listener of an event on a PV.

Class Summary

EPICSAction	This will be used as a base class for EPICS related actions.
EPICSController
EPICSMechanism	This class will be used to store the state of an EPICS mechanism and will generally be shared amongst all actions which are associated with the mechanism so that they are aware if any of the other actions are using the mechanism or an external 3rd party is using the mechanism.
JunitOCSEPICS	This class is a Junit test frame which tests the functionality of the classes which comprise the OCSEPICS package When run it will perform a sequence of tests which will verify the correct operation of the classs.
OCSAction	This class will be used to perform a specific action upon a mechanism in the ISISP/WYFFOS/INTEGRAL EPICS system.
OCSEPICSConsts	This is a class which holds constants and enumerations which will be used throughout an OCS EPICS based application.
ProcessVariable	This class wraps up an EPICS process variable (PV) into a object which can be used throughout an OCS EPICS application.
StatusVariable	This is a base class which will be inherited by all status variables which are to be included in the observing system and passed around.

Enum Summary

OCSEPICSConsts.ConversionTypes	Conversion types which are to be applied
OCSEPICSConsts.IOCSubactionStateType	These are the states that an EPICS action can take
OCSEPICSConsts.MechanismActivityStates	This enumeration reflects the possible state that a mechanism can be in.
OCSEPICSConsts.OCSActionStatesType	This enumeration reflects the states that an EPICS action can be used to model the states of an EPICS action
OCSEPICSConsts.PrematureClStatStates	These values will be used to track premature events on the clstat value before command processing is completed.
OCSEPICSConsts.PVTypes	This is an enumeration of the types of PV which are associated with an EPICS control action
OCSEPICSConsts.SubactionCompletionStates	These values will be used to report the completion state of the subactions
OCSEPICSConsts.SubactionStateType	This enumeration reflects the possible state that subactions in the instrument controller can be in.
OCSEPICSConsts.UnitType	These are the two types of values which can be associated with PV.
