LPColSetBase< R > Class Template Reference

Set of LP columns.Class LPColSetBase implements a set of LPColBase%s. Unless for memory limitations, any number of LPColBases may be added to an LPColSetBase. Single or multiple LPColBases may be added to an LPColSetBase, where each method add() comes with two different signatures. One with and one without a parameter, used for returning the DataKeys assigned to the new LPColBases by the set. See DataKey for a more detailed description of the concept of keys. For the concept of renumbering LPColBases within an LPColSetBase after removal of some LPColBases, see DataSet. More...

Detailed Description

template<class R>
class soplex::LPColSetBase< R >

Set of LP columns.

Class LPColSetBase implements a set of LPColBase%s. Unless for memory limitations, any number of LPColBases may be added to an LPColSetBase. Single or multiple LPColBases may be added to an LPColSetBase, where each method add() comes with two different signatures. One with and one without a parameter, used for returning the DataKeys assigned to the new LPColBases by the set. See DataKey for a more detailed description of the concept of keys. For the concept of renumbering LPColBases within an LPColSetBase after removal of some LPColBases, see DataSet.

Constructor & Destructor Documentation

◆ LPColSetBase() [1/3]

LPColSetBase ( int  pmax = -1,
int  pmemmax = -1 
)
explicit

Default constructor.

The user can specify the initial maximum number of columns max and the initial maximum number of nonzero entries memmax. If these parameters are omitted, a default size is used. However, one can add an arbitrary number of columns to the LPColSetBase, which may result in automated memory realllocation.
