typedef PartitionIterator atlas::partition::Partition::iterator

Constructor & Destructor Documentation

atlas::partition::Partition::Partition ( )

inline

atlas::partition::Partition::Partition ( unsigned long  n )

inlineexplicit

Undefined partition of [0,n[ with no classes yet (use |add_class|)

atlas::partition::Partition::Partition ( std::vector< unsigned long > &  f )

explicit

atlas::partition::Partition::Partition	(	std::vector< unsigned long > &	f,
		tags::UnnormalizedTag
	)

Counts the number of elements in class #c.

NOTE: Straightforward implementation. Successively computing |classSize| for all classes would cost more time then necessary.

Member Function Documentation

void atlas::partition::Partition::addToClass ( unsigned long  c, unsigned long  j  )

inline

Adds value j to class #c.

Assumes that class #c is already non-empty; that is, that j is not the first element of the class. For the first element of a class, use newClass(j) instead.

Counts the number of elements in class #c.

NOTE: Straightforward implementation. Successively computing |classSize| for all classes with this method would cost more time then necessary.

Clears all entries of d_classRep.
