Detailed Description

This class implements a CoordinateSets that will build all the subsets of a Coordinates object that are of a cardinality in a certain range.

This is a less flexible class than FromRanges but, in the example Subsets.cc it has been slightly faster in our tests.

Remarks

it is somewhat hard to build an object of this class, maybe this could be done in a better way.

Constructor & Destructor Documentation

Subsets()

LatticeTester::CoordinateSets::Subsets::Subsets	(	const Coordinates &	coords,
		Coordinates::size_type	minOrder,
		Coordinates::size_type	maxOrder )

Constructs a set of all subsets of coords with minimum and maximum cardinality specified by minOrder and maxOrder.

For example, to select all 1, 2, and 3-tuples over coordinates 2, 4, 6, one may use the declaration Subsets tousens(ens, 1, 3), where set ens is {2,4,6}; this gives the sets tousens = {{2}, {4}, {6}, {2, 4}, {2, 6}, {4, 6}, {2, 4, 6}}.

References coords(), maxOrder(), and minOrder().
