Package org.ojalgo.array

Class OffHeapArray

java.lang.Object

org.ojalgo.array.BasicArray<Double>

org.ojalgo.array.DenseArray<Double>

org.ojalgo.array.OffHeapArray

All Implemented Interfaces:

Access1D<Double>, Access1D.Aggregatable<Double>, Access1D.Collectable<Double,Mutate1D>, Access1D.Visitable<Double>, Factory1D.Builder<DenseArray<Double>>, Mutate1D, Mutate1D.Fillable<Double>, Mutate1D.Modifiable<Double>, Structure1D

Direct Known Subclasses:

OffHeapR032, OffHeapR064, OffHeapZ008, OffHeapZ016, OffHeapZ032, OffHeapZ064

public abstract class OffHeapArray
extends DenseArray<Double>

Off heap memory array.

When just instantiated these array classes contain uninitialized memory – memory is allocated but not initialized. To initialize call Mutate1D.reset(). Explicit initialization is only necessary if your code depends on having zeros as the default/initial value.
