public final class RandomAccessibleIntervalCursor<T>
extends AbstractInterval
implements Cursor<T>

A Cursor that iterates any RandomAccessibleInterval by moving a RandomAccess in flat iteration order. Localizable calls are forwarded to the RandomAccess.

RandomAccessibleIntervalCursor

public RandomAccessibleIntervalCursor(I interval)

RandomAccessibleIntervalCursor

public RandomAccessibleIntervalCursor(RandomAccessible<T> randomAccessible,
                                      Interval interval)

RandomAccessibleIntervalCursor

protected RandomAccessibleIntervalCursor(RandomAccessibleIntervalCursor<T> cursor)

Method Detail

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

jumpFwd

public void jumpFwd(long steps)

Description copied from interface: Iterator

Move steps × forward.

Highly recommended to override this with a more efficient version.

Specified by:

jumpFwd in interface Iterator

Parameters:

steps - number of steps to move forward

fwd

public void fwd()

Description copied from interface: Iterator

Move forward.

Specified by:

fwd in interface Iterator

nextLine

private void nextLine()

reset

public void reset()

Description copied from interface: Iterator

Reset the Iterator, that is put it to where it would be if newly created.

Specified by:

reset in interface Iterator

hasNext

public boolean hasNext()

Description copied from interface: Iterator

Returns true if another step forward is possible.

Specified by:

hasNext in interface java.util.Iterator<T>

Specified by:

hasNext in interface Iterator

Returns:

true, if there is another step forward is possible, otherwise false

copy

public RandomAccessibleIntervalCursor<T> copy()

Specified by:

copy in interface Cursor<T>

Specified by:

copy in interface RealCursor<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)

localize

public void localize(float[] position)

Description copied from interface: RealLocalizable

Write the current position into the passed array.

Specified by:

localize in interface RealLocalizable

Parameters:

position - receives current position, length must be ≥ EuclideanSpace.numDimensions()

localize

public void localize(double[] position)

Description copied from interface: RealLocalizable

Write the current position into the passed array.

Specified by:

localize in interface RealLocalizable

Parameters:

position - receives current position, length must be ≥ EuclideanSpace.numDimensions()

getFloatPosition

public float getFloatPosition(int d)

Description copied from interface: RealLocalizable

Return the current position in a given dimension.

Specified by:

getFloatPosition in interface Localizable

Specified by:

getFloatPosition in interface RealLocalizable

Parameters:

d - dimension

Returns:

dimension of current position

getDoublePosition

public double getDoublePosition(int d)

Description copied from interface: RealLocalizable

Return the current position in a given dimension.

Specified by:

getDoublePosition in interface Localizable

Specified by:

getDoublePosition in interface RealLocalizable

Parameters:

dimension of current position

localize

public void localize(int[] position)

Description copied from interface: Localizable

localize

public void localize(long[] position)

Description copied from interface: Localizable

Write the current position into the passed array.

Specified by:

localize in interface Localizable

Parameters:

position - receives current position, length must be ≥ EuclideanSpace.numDimensions()

getIntPosition

public int getIntPosition(int d)

Description copied from interface: Localizable

Return the current position in a given dimension.

Specified by:

getIntPosition in interface Localizable

Parameters:

d - dimension

Returns:

dimension of current position

getLongPosition

public long getLongPosition(int d)

Description copied from interface: Localizable

getLongPosition in interface Localizable

Parameters:

d - dimension

Returns:

dimension of current position
