Class FullSourceMapMixedRandomAccess<T>

java.lang.Object

net.imglib2.AbstractEuclideanSpace

net.imglib2.view.FullSourceMapMixedRandomAccess<T>

Type Parameters:

T -

All Implemented Interfaces:

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

public final class FullSourceMapMixedRandomAccess<T>
extends AbstractEuclideanSpace
implements RandomAccess<T>

Wrap a source RandomAccess which is related to this by a Mixed transformToSource. This is for Mixed transforms that feature a full mapping of source to target components. That is, there is no down-projection, no source component is discarded. In this case, the current position can be recovered from the position of the source RandomAccess. Localize can be implemented via localize on the source RandomAccess.

For the general case, see MixedRandomAccess.

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)
