Examples of Indices

cc.redberry.core.indices.Indices
This interface states common tensor indices functionality. For specification and more information see methods summary and implementations. Indices objects are considered to be immutable, so there is no way to change the indices object.
For individual index structure (bit masks in the int representation) see IndicesUtils.

lupos.engine.operators.index.Indices
Instances of this class are used as data structure for storing triples indexed by various criteria.
