base trigger class

Variables:

  • required_csets – If None, all csets are passed in, else it must be a sequence, those specific csets are passed in

  • _label – Either None, or a string to use for this triggers label

  • _hook – sequence of hook points to register into

  • priority – range of 0 to 100, order of execution for triggers per hook

  • _engine_types – if None, trigger works for all engine modes, else it’s limited to that mode, and must be a sequence

‘localize’ a trigger to a specific merge engine process mainly used if the trigger comes from configuration
