Examples of cc.redberry.core.combinatorics.Symmetries

cc.redberry.core.combinatorics.Symmetries
This class is a representation of {@link Symmetry} set. It holds a set ofsymmetries and provides common functionality: adding {@code Symmetry} anditerating over all possible symmetries, which can be generated by compositions of keeping symmetries. Also, it watches that all keeping symmetries are consistent, i.e. it throws {@link InconsistentGeneratorsException}when trying to add symmetry, which is inconsistent with already added symmetries. All adding combinatorics must have the same dimension, which specified at initialization. For more details see method summary. @see Symmetry @see PermutationsSpanIterator @author Dmitry Bolotin @author Stanislav Poslavsky
