void SCIPconshdlrSetData	(	SCIP_CONSHDLR *	conshdlr,
		SCIP_CONSHDLRDATA *	conshdlrdata

sets user data of constraint handler; user has to free old data in advance!

Parameters

conshdlr	constraint handler
conshdlrdata	new constraint handler user data

		SCIP_DECL_CONSSEPASOL((*conssepasol))	,
		int	sepafreq,
		int	sepapriority,
		SCIP_Bool	delaysepa
	)

sets all separation related callbacks of the constraint handler

Parameters

conshdlr	constraint handler
sepafreq	frequency for separating cuts; zero means to separate only in the root node
sepapriority	priority of the constraint handler for separation
delaysepa	should separation method be delayed, if other separators found cuts?

	)

sets both the propagation callback and the propagation frequency of the constraint handler

Parameters

conshdlr	constraint handler
propfreq	frequency for propagating domains; zero means only preprocessing propagation
delayprop	should propagation method be delayed, if other propagators found reductions?
timingmask	positions in the node solving loop where propagators should be executed

SCIP_CONS** SCIPconshdlrGetConss ( SCIP_CONSHDLR * conshdlr )

gets array with constraints of constraint handler; the first SCIPconshdlrGetNActiveConss() entries are the active constraints, the last SCIPconshdlrGetNConss() - SCIPconshdlrGetNActiveConss() constraints are deactivated

Note: A constraint is active if it is global and was not removed or it was added locally (in that case the local flag is TRUE) and the current node belongs to the corresponding sub tree.
