Class RepeatedElementVector

java.lang.Object

mikera.arrayz.impl.AbstractArray<Double>

mikera.vectorz.AVector

mikera.vectorz.impl.AConstrainedVector

mikera.vectorz.impl.RepeatedElementVector

All Implemented Interfaces:

Serializable, Cloneable, Comparable<AVector>, Iterable<Double>, INDArray, IVector

public final class RepeatedElementVector
extends AConstrainedVector

A mutable vector that always has a single repeated component. Setting any component will therefore set all components.
