Member Function Documentation

__init__ (  client  , parent  = None )

Initialize valid registers as Gattrs. Assign default values to members

disableMask (   )

Disables all trigger masks but doesn't change the cached mask value. This way when the triggers are enabled again, the old setting can be applied.

enableMask (   )

Commits the mask value to hardware. Returns: The value of the dirty flag before the commit is made.

getDisableTime (   )

Returns the VxWorks timestamp at the time the triggers are disabled. Returns: Trigger disable time

getEnableTime (   )

Returns the VxWorks timestamp at the time the triggers are enabled. Returns: Trigger enable time

isMaskDirty (   )

Return the mask dirty flag. Returns: Mask dirty flag.

setDestinationOverride (  override   )

Sets the flag to determine whether the user should be able to override the destination value. Parameters: override  0=Destination is supplied as the LCB address as returned by CmdCli.getLcbAddr() 1=The user supplied destination value takes effect

triggersDisabled (   )

Check if the triggers are disabled. Returns: True if triggers are disabled, False if triggers are disabled.

waitForMaskEnable (  tmo  = None  )

Waits until the enableMask() method is called. This is usually needed by non-self-triggering scripts where the _commandSynch thread needs to wait until RunControl actually enables the mask before continuing. Parameters: tmo  Optional parameter giving the wait timeout in seconds
