Class IntVectorStorage

java.lang.Object

org.processmining.specpp.datastructures.vectorization.IntVectorStorage

All Implemented Interfaces:

Mappable<java.util.function.IntUnaryOperator>, Mathable<IntVectorStorage>, Copyable<IntVectorStorage>, PartiallyOrdered<IntVectorStorage>

Direct Known Subclasses:

IntVectorSubsetStorage

public class IntVectorStorage
extends java.lang.Object
implements Copyable<IntVectorStorage>, Mathable<IntVectorStorage>, Mappable<java.util.function.IntUnaryOperator>, PartiallyOrdered<IntVectorStorage>

Datastructure for storing a (fixed-size) vector of (fixed-, but not necessarily equal, -sized) vectors of integers in contingent memory. Provides vector wise access, efficient mapping and comparison (e.g. ordering relation) operations. Additionally, this implementation is spliterable over the vectors with or without their index.

Used as a representation of encoded (activities to integers) log variants as well as variant marking histories.
