Detailed Description

Like the class ABA_NUMVAR for variables we provide the class ABA_NUMCON for constraints which are uniquely defined by an integer number.

Parameters:

int

number_ The identification number of the constraint.

Constructor & Destructor Documentation

ABA_NUMCON::ABA_NUMCON	(	ABA_MASTER *	master,
		const ABA_SUB *	sub,
		ABA_CSENSE::SENSE	sense,
		bool	dynamic,
		bool	local,
		bool	liftable,
		int	number,
		double	rhs
	)

The constructor.

Parameters:

	master	A pointer to the corresponding master of the optimization.
	sub	A pointer to the subproblem associated with the constraint. This can be also the 0-pointer.
	sense	The sense of the constraint.
	dynamic	If this argument is true, then the constraint can be removed from the active constraint set during the cutting plane phase of the subproblem optimization.
	local	If this argument is true, then the constraint is considered to be only locally valid. As a local constraint is associated with a subproblem, sub must not be 0 if local is true.
	liftable	If this argument is true, then a lifting procedure must be available, i.e., that the coefficients of variables which have not been active at generation time of the constraint can be computed.
	number	The identification number of the constraint.
	rhs	The right hand side of the constraint.

virtual ABA_NUMCON::~ABA_NUMCON

[virtual]

The destructor.

Member Function Documentation

virtual double ABA_NUMCON::coeff

(

ABA_VARIABLE *

v

)

[virtual]

Returns:

The coefficient of the variable v.

Parameters:

v

The variable of which the coefficient is determined. It must point to an object of the class ABA_COLVAR.

Implements ABA_CONSTRAINT.

virtual void ABA_NUMCON::print

(

ostream &

out

)

[virtual]

Writes the row format of the constraint on an output stream.

It redefines the virtual function print() of the base class ABA_CONVAR.

Parameters:

out

The output stream.

Reimplemented from ABA_CONVAR.

int ABA_NUMCON::number

(

)

const [inline]

Returns:

Returns the identification number of the constraint.

Definition at line 130 of file numcon.h.

Friends And Related Function Documentation

ostream& operator<<	(	ostream &	out,
		const ABA_NUMCON &	rhs
	)			[friend]

The output operator writes the identification number and the right hand side to an output stream.

Returns:

A reference to the output stream.

Parameters:

	out	The output stream.
	rhs	The variable being output.
