Class SectionIterable

java.lang.Object

ucar.ma2.SectionIterable

All Implemented Interfaces:

java.lang.Iterable<java.lang.Integer>

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

A Section composed of List instead of List. 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.

Method Detail

computeSize

public long computeSize()

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

getRange

public RangeIterator getRange(int i)

getRank

public int getRank()

getShape

public int[] getShape()

iterator

public java.util.Iterator<java.lang.Integer> iterator()

Specified by:

iterator in interface java.lang.Iterable<java.lang.Integer>

subSection

public SectionIterable subSection(int start,
                                  int endExclusive)
