de.jreality.scene.data.DoubleArrayArray

All Implemented Interfaces:

Serializable, Iterable, Collection, List

Direct Known Subclasses:

DoubleArrayArray.Array, DoubleArrayArray.Inlined

public abstract class DoubleArrayArray
extends DataList

An immutable array of DoubleArrays. A good JIT compiler optimizes this such that access it is not slower as for the pure array. The advantage is, that only the creator who provided the array is allowed to change it. This class is abstract it leaves the implementation and especially the storage model to its subclasses.
