Class SectionIterable

java.lang.Object

ucar.array.SectionIterable

All Implemented Interfaces:

Iterable<Integer>

@Immutable
public class SectionIterable
extends Object
implements Iterable<Integer>

A Section composed of List<RangeIterator> rather than List&t;Range>. SectionIterable knows the fullShape of which it is a section. The iteration is over the elements in the section, returning 1D index into the full shape.

Specified by:

iterator in interface Iterable<Integer>

getIterator

public SectionIterable.SectionIterator getIterator()

Iterate over a section, returning the index in an equivalent 1D array of shape[] So this is a section in a (possibly) larger array described by shape[]. The index is in the "source" array.

Returns:

iterator over this section
