Method Detail

empty

OMasSignedSet empty()

This does not, and will not, work. This is inherited from the SetFactory interface, and is not appropriate for Oriented Matroids.

Specified by:

empty in interface SetFactory<SignedSet,OMasSignedSet>

Returns:

Never.

Throws:

UnsupportedOperationException - Always.

fromSignedSets

net.sf.oriented.impl.om.OMSInternal fromSignedSets(Label[] ground,
                                                 SetOfSignedSet sym)

Parameters:

ground - The ground set from which the symmetric sets are taken.

sym - A symmetric set of signed sets, satisfying all the relevant axioms.

Returns:

A new Oriented Matroid, based on the signed sets.
