net.imglib2.AbstractCursorInt<T>

Type Parameters:

T -

All Implemented Interfaces:

public abstract class AbstractCursorInt<T>
extends AbstractEuclideanSpace
implements Cursor<T>

Abstract implementation of Cursor. Java's Iterator interface is implemented by mapping to abstract Iterator.fwd() and Sampler.get().

For localization, default implementations are available that all build on the abstract int variant. For particular cursors, this may be implemented more efficiently saving at least one loop over n.

This is identical to AbstractCursor, except that default implementations build on the abstract int instead of long variant here.

Constructor Details

AbstractCursorInt

public AbstractCursorInt(int n)

Parameters:

n - number of dimensions in the Img.

Method Details

localize

public void localize(float[] pos)

Description copied from interface: RealLocalizable

Write the current position into the passed array.

Specified by:

localize in interface RealLocalizable

Parameters:

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

localize

public void localize(double[] pos)

Description copied from interface: RealLocalizable

Write the current position into the passed array.

Specified by:

localize in interface RealLocalizable

Parameters:

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

localize

public void localize(long[] pos)

Description copied from interface: Localizable

Write the current position into the passed array.

Specified by:

localize in interface Localizable

Parameters:

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

localize

public void localize(Positionable position)

Description copied from interface: Localizable

Write the current position into the passed Positionable. Note for developers: This default implementation forwards to Positionable.setPosition(Localizable), so don't do the same there.

Specified by:

localize in interface Localizable

Parameters:

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

localize

public void localize(RealPositionable position)

Description copied from interface: RealLocalizable

Write the current position into the passed Positionable. Note for developers: This default implementation forwards to RealPositionable.setPosition(RealLocalizable), so don't do the same there.

Specified by:

localize in interface Localizable

Specified by:

localize in interface RealLocalizable

Parameters:

position - receives current position EuclideanSpace.numDimensions() 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:

d - dimension

Returns:

dimension of current position

getLongPosition

public long getLongPosition(int d)

Description copied from interface: Localizable

Return the current position in a given dimension.

Specified by:

getLongPosition in interface Localizable

Parameters:

d - dimension

Returns:

dimension of current position

toString

public String toString()

Overrides:

toString in class Object

copy

public abstract AbstractCursorInt<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)
