Member Function Documentation

returnValue PointConstraint::add	(	const double	lb_,
		const Expression &	arg,
		const double	ub_
	)

Adds a point-constraint component.

Returns: SUCCESSFUL_RETURN RET_MEMBER_NOT_INITIALISED (if the ConstraintElement::fcn is not initialized)

Definition at line 148 of file point_constraint.cpp.

returnValue PointConstraint::computeForwardSensitivityBlock	(	int	offset,
		int	offset2,
		DMatrix *	seed
	)

inlineprotected

only for internal use (routine which computes a part of the block matrix needed for forward differentiation.)

Definition at line 677 of file point_constraint.cpp.

returnValue PointConstraint::evaluate ( const OCPiterate & iter )

Evaluates all components in this constraint and stores the
residuum.

Returns: SUCESSFUL_RETURN

Definition at line 190 of file point_constraint.cpp.

returnValue PointConstraint::evaluateSensitivities ( )

Evaluates the sensitivities of all components in this
constraint. Note that the seed can be defined via the base
class ConstraintElement.

Returns: SUCESSFUL_RETURN

Definition at line 225 of file point_constraint.cpp.

returnValue PointConstraint::evaluateSensitivities	(	const DMatrix &	seed,
		BlockMatrix &	hessian
	)

Evaluates the sensitivities and Hessian.

Returns: SUCESSFUL_RETURN

Definition at line 341 of file point_constraint.cpp.

returnValue PointConstraint::getBounds ( const OCPiterate & iter )

Writes a special copy of the bounds that is needed within the OptimizationAlgorithm into the optimization variables.

Definition at line 605 of file point_constraint.cpp.

int PointConstraint::getNC ( ) const

inline

returns the number of constraints

BooleanType PointConstraint::isBoxConstraint ( ) const

inline

returns whether object only comprises box constraints.

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

Assignment operator (deep copy).

Definition at line 107 of file point_constraint.cpp.
