Class StridedElementIterator

java.lang.Object

mikera.matrixx.impl.StridedElementIterator

All Implemented Interfaces:

java.util.Iterator<java.lang.Double>

public class StridedElementIterator
extends java.lang.Object
implements java.util.Iterator<java.lang.Double>

Iterator over strided matrix array elements. This is an optimised / specialised element iterator for strided matrices that otherwise performs the same function as MatrixElementIterator. Performance tricks used: - Caches the data array reference - Caches the underlying stride data to avoid re-checking the strided matrix - Hopefully fits the full iterator data in a 64-byte cache line
