NtreeImg

private NtreeImg(NtreeImg<T,A> img)

Method Details

update

public A update(Object updater)

Description copied from interface: NativeImg

called by type with cursor.

Specified by:

update in interface NativeImg<T extends NativeType<T>, A extends NtreeAccess<?,A>>

Parameters:

updater - cursor

Returns:

DataAccess which is referred to by the updater

randomAccess

public NtreeRandomAccess<T> randomAccess()

Description copied from interface: RandomAccessible

Create a random access sampler for integer coordinates.

The returned random access covers as much of the domain as possible.

Please note: RandomAccessibleIntervals have a finite domain (their Interval), so RandomAccessible.randomAccess() is only guaranteed to cover this finite domain. This may lead to unexpected results when using Views. In the following code

RandomAccessible<T> extended = Views.extendBorder( img )
RandomAccessibleInterval<T> cropped = Views.interval( extended, img );
RandomAccess<T> a1 = extended.randomAccess();
RandomAccess<T> a2 = cropped.randomAccess();

The access a1 on the extended image is valid everywhere. However, somewhat counter-intuitively, the access a2 on the extended and cropped image is only valid on the interval img to which the extended image was cropped. The access is only required to cover this interval, because it is the domain of the cropped image. Views attempts to provide the fastest possible access that meets this requirement, and will therefore strip the extension. To deal with this, if you know that you need to access pixels outside the domain of the RandomAccessibleInterval, and you know that the RandomAccessibleInterval is actually defined beyond its interval boundaries, then use the RandomAccessible.randomAccess(Interval) variant and specify which interval you actually want to access. In the above example,

RandomAccess<T> a2 = cropped.randomAccess( Intervals.expand( img, 10 ) );

will provide the extended access as expected.

Specified by:

randomAccess in interface RandomAccessible<T extends NativeType<T>>

Returns:

random access sampler

cursor

public NtreeCursor<T> cursor()

Description copied from interface: IterableRealInterval

Returns a RealCursor that iterates with optimal speed without calculating the location at each iteration step. Localization is performed on demand.

Use this where localization is required rarely/ not for each iteration.

Specified by:

cursor in interface IterableInterval<T extends NativeType<T>>

Specified by:

cursor in interface IterableRealInterval<T extends NativeType<T>>

Specified by:

cursor in interface RandomAccessibleInterval<T extends NativeType<T>>

Returns:

fast iterating iterator

localizingCursor

public NtreeCursor<T> localizingCursor()

Description copied from interface: IterableRealInterval

Returns a RealLocalizable Iterator that calculates its location at each iteration step. That is, localization is performed with optimal speed.

Use this where localization is required often/ for each iteration.

Specified by:

localizingCursor in interface IterableInterval<T extends NativeType<T>>

Specified by:

localizingCursor in interface IterableRealInterval<T extends NativeType<T>>

Specified by:

localizingCursor in interface RandomAccessibleInterval<T extends NativeType<T>>

Returns:

fast localizing iterator

factory

public ImgFactory<T> factory()

Description copied from interface: Img

Get a ImgFactory that creates Imgs of the same kind as this one. This is useful to create Imgs for temporary storage in generic methods where the specific Img type is unknown. Note, that the factory can be used even if all references to this Img have been invalidated.

Specified by:

factory in interface Img<T extends NativeType<T>>

Returns:

a factory for Imgs of the same kind as this one.

copy

public NtreeImg<T,A> copy()

Specified by:

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

Returns:

- A copy of the current Img instance, all pixels are duplicated

iterationOrder

public FlatIterationOrder iterationOrder()

Description copied from interface: IterableRealInterval

Returns the iteration order of this IterableRealInterval. If the returned object equals (Object.equals(Object)) the iteration order of another IterableRealInterval f then they can be copied by synchronous iteration. That is, having an Iterator on this and another Iterator on f, moving both in synchrony will point both of them to corresponding locations in their source domain. In other words, this and f have the same iteration order and means and the same number of elements.

Specified by:

iterationOrder in interface IterableRealInterval<T extends NativeType<T>>

Specified by:

iterationOrder in interface RandomAccessibleInterval<T extends NativeType<T>>

Returns:

the iteration order of this IterableRealInterval.
