ExecStatus Gecode::Int::Cumulatives::Val< ViewM, ViewD, ViewH, View >::propagate	(	Space *	home,
		ModEventDelta	med
	)			[inline, virtual]

Propagation function.

The propagation function must return an execution status as follows:

• ES_FAILED: the propagator has detected failure
• ES_NOFIX: the propagator has done propagation
• ES_FIX: the propagator has done propagation and has computed a fixpoint. That is, running the propagator immediately again will do nothing.

Apart from the above values, a propagator can return the result from calling one of the functions

• ES_SUBSUMED: the propagator is subsumed and has been already deleted.
• ES_NOFIX_PARTIAL: the propagator has consumed some of its propagation events.
• ES_FIX_PARTIAL: the propagator has consumed some of its propagation events and with respect to these events is at fixpoint For more details, see the individual functions.
