Method Detail

fwd

public void fwd(int d)

Description copied from interface: Positionable

Move by 1 in one dimension.

Specified by:

fwd in interface Positionable

Parameters:

d - dimension

bck

public void bck(int d)

Description copied from interface: Positionable

Move by -1 in one dimension.

Specified by:

bck in interface Positionable

Parameters:

d - dimension

move

public void move(long distance,
                 int d)

Description copied from interface: Positionable

Move the element in one dimension for some distance.

Specified by:

move in interface Positionable

Parameters:

distance - relative offset in dimension d

d - dimension

setPosition

public void setPosition(int[] pos)

Description copied from interface: Positionable

Set the position of the element.

Specified by:

setPosition in interface Positionable

Parameters:

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

setPosition

public void setPosition(long[] pos)

Description copied from interface: Positionable

Set the position of the element.

Specified by:

setPosition in interface Positionable

Parameters:

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

setPosition

public void setPosition(long pos,
                        int d)

Description copied from interface: Positionable

Set the position of the element for one dimension.

Specified by:

setPosition in interface Positionable

Parameters:

pos - absolute position in dimension d

d - dimension

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 extends NativeType<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 extends NativeType<T>>

Specified by:

getType in interface Typed<T extends NativeType<T>>

Returns:

an instance of T

copy

public NtreeRandomAccess<T> copy()

Specified by:

copy in interface RandomAccess<T extends NativeType<T>>

Specified by:

copy in interface Sampler<T extends NativeType<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)

Specified by:

getPosition in interface NtreeImg.PositionProvider
