IndexedTensor.SubspaceIterator (vespajlib 7.534.29 API)

java.lang.Object
- com.yahoo.tensor.IndexedTensor.SubspaceIterator

All Implemented Interfaces:

Iterator<Tensor.Cell>

Enclosing class:

IndexedTensor
```
public final class IndexedTensor.SubspaceIterator
extends Object
implements 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.

Method Summary

Modifier and Type	Method	Description
`TensorAddress`	`address()`	Returns the address of the cell this currently points to (which may be an invalid position)
`boolean`	`hasNext()`
`Tensor.Cell`	`next()`	Returns the next cell, which is valid until next() is called again
`void`	`reset()`	Rewind this iterator to the first element
