Class IndexedTensor.SubspaceIterator

  • All Implemented Interfaces:
    java.util.Iterator<Tensor.Cell>
    Enclosing class:
    IndexedTensor
    public final class IndexedTensor.SubspaceIterator
extends java.lang.Object
implements java.util.Iterator<Tensor.Cell>
    An iterator over a subspace of this tensor. This is exposed to allow clients to query the size. NOTE THAT the Cell returned by next is only valid until the next() call is made. This is a concession to performance due to this typically being used in inner loops.
