java.lang.Object

xal.ca.ChannelFactory

xal.plugin.epics7.Epics7ChannelFactory

public class Epics7ChannelFactory
extends ChannelFactory

NOTE: previous implementations kept a cache of native channels, but that is not required since ChannelFactory keeps a list of Open XAL Channels, which can create only 1 native channel each. TODO: test if it works when connecting to 2 different fields of the same PV.
