public void move(Localizable localizable)

Description copied from interface: Positionable

Move the element relative to its current location using an Localizable as distance vector.

Specified by:

move in interface Positionable

Parameters:

localizable - relative offset, EuclideanSpace.numDimensions() must be ≥ EuclideanSpace.numDimensions()

Parameters:

localizable - absolute position, EuclideanSpace.numDimensions() must be ≥ EuclideanSpace.numDimensions()

setPosition

public void setPosition(int[] position)

Description copied from interface: Positionable

get

public T get()

Description copied from interface: Sampler

Access the actual T instance providing access to a pixel, sub-pixel or integral region value the Sampler points at.

Specified by:

get in interface Sampler<T>

getType

public T getType()

Description copied from interface: Typed

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.

Specified by:

getType in interface Sampler<T>

Specified by:

getType in interface Typed<T>

Returns:

an instance of T

copy

public MixedRandomAccess<T> copy()

Specified by:

copy in interface RandomAccess<T>

Specified by:

copy in interface Sampler<T>

Returns:

- 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)
