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

Detailed Description

template<class R>
class soplex::LPRowSetBase< R >

Set of LP rows.

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

◆ LPRowSetBase() [1/3]

LPRowSetBase	(	int	pmax = `-1`,
		int	pmemmax = `-1`
	)

explicit

Default constructor.

The user can specify the initial maximum number of rows 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 rows to the LPRowSetBase, which may result in automated memory realllocation.
