Detailed Description

template<class R>
class soplex::SVSetBase< R >

Sparse vector set.

Class SVSetBase provides a set of sparse vectors SVectorBase. All SVectorBases in an SVSetBase share one big memory block for their nonzeros. This memory is referred to as the nonzero memory. The SVectorBases themselves are saved in another memory block referred to as the vector memory. Both memory blocks will grow automatically if required, when adding more SVectorBases to the set or enlarging SVectorBases within the set. For controlling memory consumption, methods are provided to inquire and reset the size of the memory blocks used for vectors and nonzeros.

SVectorBases in an SVSetBase are numbered from 0 thru num()-1. They can be accessed using the index operator[](). When removing SVectorBases of a SVSetBase the remaining ones will be renumbered. However, all SVectorBase with a smaller number than the lowest number of the removed SVectorBases will remain unchanged.

For providing a uniform access to SVectorBases in a set even if others are removed or added, SVSetBase assigns a DataKey to each SVectorBase in the set. Such a DataKey remains unchanged as long as the corresponding SVectorBase is in the SVSetBase, no matter what other SVectorBases are added to or removed from the SVSetBase. Methods are provided for getting the DataKey to a SVectorBase or its number and vice versa. Further, each add() method for enlarging an SVSetBase is provided with two signatures. One of them returns the DataKeys assigned to the SVectorBases added to the SVSetBase.

◆ memPack()

void memPack ( )

Garbage collection in nonzero memory.

Pack the svectors together as tightly as possible. This removes all additional unused memory, i.e., size = max for every svector after the call.

Note: do not call isConsistent() here, because the following might happen: In SPxLP::doAddRows(const LPRowSet& p_set), when adding rows, the sizes of the vectors for the columns of the LP are increased (without yet filling in the data) to recieve the additional entries. This is done by calling xtend() above. xtend() in turn might call this method, which checks the yet unfilled positions, i.e., isConsistent() is likely to fail. In general, isConsistent() should not be called within this class, but in classes further up in the hierarchy.
