use of org.csstudio.simplepv.IPV in project yamcs-studio by yamcs.

the class PVUtil method createPV.

/**
 * Create a PV and start it. PVListener can be added to the PV to monitor its value change, but please note that the
 * listener is executed in non-UI thread. If the code need be executed in UI thread, please use
 * {@link ScriptUtil#execInUI(Runnable, AbstractBaseEditPart)}. The monitor's maximum update rate is 50hz. If the PV
 * updates faster than this rate, some updates will be discarded.
 *
 * @param name
 *            name of the PV.
 * @param widget
 *            the reference widget. The PV will stop when the widget is deactivated, so it is not needed to stop the
 *            pv in script.
 * @return the PV.
 * @throws Exception
 *             the exception that might happen while creating the pv.
