Detailed Description

Class of Vectors consisting of other vectors.

This vector is a vector that consists of zero, one or more Vector's which are stacked on each others: $x_{\rm compound} = \left(\begin{array}{c}x_0\\\dots\\x_{{\rm ncomps} - 1}\end{array}\right)$ . The individual components can be associated to different VectorSpaces. The individual components can also be const and non-const Vectors.

Constructor & Destructor Documentation

Ipopt::CompoundVector::CompoundVector	(	const CompoundVectorSpace *	owner_space,
		bool	create_new
	)

Constructor, given the corresponding CompoundVectorSpace.

Before this constructor can be called, all components of the CompoundVectorSpace have to be set, so that the constructors for the individual components can be called. If the flag create_new is true, then the individual components of the new CompoundVector are initialized with the MakeNew methods of each VectorSpace (and are non-const). Otherwise, the individual components can later be set using the SetComp and SetCompNonConst method.

virtual Ipopt::CompoundVector::~CompoundVector ( ) [virtual]

Default destructor.

Ipopt::CompoundVector::CompoundVector ( ) [private]

Default Constructor.

Ipopt::CompoundVector::CompoundVector ( const CompoundVector & ) [private]

Copy Constructor.
