Member Function Documentation

CbcFixingBranchingObject& CbcFixingBranchingObject::operator= ( const CbcFixingBranchingObject & rhs )

Assignment operator.

Reimplemented from CbcBranchingObject.

virtual CbcBranchingObject* CbcFixingBranchingObject::clone ( ) const [virtual]

Clone.

Implements CbcBranchingObject.

virtual double CbcFixingBranchingObject::branch ( ) [virtual]

Does next branch and updates state.

Implements CbcBranchingObject.

virtual void CbcFixingBranchingObject::print ( ) [virtual]

Print something about branch - only if log level high.

virtual int CbcFixingBranchingObject::type ( ) const [inline, virtual]

Return the type (an integer identifier) of this.

Implements CbcBranchingObject.

Definition at line 1228 of file CbcBranchActual.hpp.

virtual int CbcFixingBranchingObject::compareOriginalObject ( const CbcBranchingObject * brObj ) const [virtual]

Compare the original object of this with the original object of brObj.

Assumes that there is an ordering of the original objects. This method should be invoked only if this and brObj are of the same type. Return negative/0/positive depending on whether this is smaller/same/larger than the argument.

virtual CbcRangeCompare CbcFixingBranchingObject::compareBranchingObject	(	const CbcBranchingObject *	brObj,
		const bool	replaceIfOverlap = `false`
	)			`[virtual]`

Compare the this with brObj.

this and brObj must be os the same type and must have the same original object, but they may have different feasible regions. Return the appropriate CbcRangeCompare value (first argument being the sub/superset if that's the case). In case of overlap (and if replaceIfOverlap is true) replace the current branching object with one whose feasible region is the overlap.
