Package net.imglib2.iterator

Class LocalizingRealIntervalIterator

java.lang.Object

net.imglib2.AbstractEuclideanSpace

net.imglib2.AbstractRealInterval

net.imglib2.iterator.LocalizingRealIntervalIterator

All Implemented Interfaces:

EuclideanSpace, Iterator, RealInterval, RealLocalizable

public class LocalizingRealIntervalIterator
extends AbstractRealInterval
implements Iterator, RealLocalizable

Use this class to iterate a virtual RealInterval in flat order, that is: with the first dimension varying most quickly and the last dimension varying most slowly. This is useful for iterating an arbitrary real interval in a defined order.

Constructor Details

LocalizingRealIntervalIterator

public LocalizingRealIntervalIterator(RealInterval interval,
 double[] step)

Iterates an RealInterval with given min and max with the provided step along each dimension.

Parameters:

interval - the real interval

step - iteration step

LocalizingRealIntervalIterator

public LocalizingRealIntervalIterator(double[] min,
 double[] max,
 double[] step)

Iterates an RealInterval with given min and max the the provided step along each dimension.

Parameters:

min - real interval min

max - real interval min

step - iteration steps

Method Details

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 Iterator

Returns:

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

toString

public String toString()

Overrides:

toString in class AbstractRealInterval

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 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 RealLocalizable

Parameters:

d - dimension

dimension of current position

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

fwdDim

private void fwdDim(int d)
