Package net.imglib2.view

Class StackView.DefaultRA<T>

java.lang.Object

net.imglib2.view.StackView.DefaultRA<T>

Type Parameters:

T - the pixel type

All Implemented Interfaces:

EuclideanSpace, Localizable, Positionable, RandomAccess<T>, RealLocalizable, Sampler<T>, Typed<T>

Enclosing class:

StackView<T>

public static final class StackView.DefaultRA<T>
extends java.lang.Object
implements RandomAccess<T>

A RandomAccess on a StackView. It keeps a list of RandomAccesses on all constituent hyper-slices of the StackView.

When changing any dimension of the position, except the (n+1)th, this position change is applied to the active slice RandomAccess. When changing the (n+1)th dimension of the position, a new slice RandomAccess becomes active is set to the position of the previously active slice RandomAccess.

Get an instance of T.

It should not be assumed that the returned T instance is an independent copy. In particular, repeated calls to getType() may return the same instance.

- A new Sampler in the same state accessing the same values. It does NOT copy T, just the state of the Sampler. Otherwise use T.copy() if available. Sampler.copy().get() == Sampler.get(), i.e. both hold the same value, not necessarily the same instance (this is the case for an ArrayCursor for example)
