Package net.imglib2.img.list
Class AbstractLongListImg<T>
java.lang.Object
net.imglib2.img.AbstractImg<T>
net.imglib2.img.list.AbstractLongListImg<T>
- Type Parameters:
T
- The value type of the pixels. You can usType
s or arbitraryObject
s. If you use non-Type
pixels you cannot useType.set(Type)
to change the value stored in every reference. Instead, you can use theAbstractLongListImg.LongListCursor.set(Object)
andAbstractLongListImg.LongListRandomAccess.set(Object)
methods to alter pixels.
- All Implemented Interfaces:
Iterable<T>
,Dimensions
,EuclideanSpace
,Img<T>
,Interval
,IterableInterval<T>
,IterableRealInterval<T>
,RandomAccessible<T>
,RandomAccessibleInterval<T>
,RealInterval
- Direct Known Subclasses:
LazyCellImg.LazyCells
Abstract base class for
Img
that store pixels in a single linear
list addressed by a long. The number of entities that can be addressed is
limited to Long.MAX_VALUE
.
Derived classes need to implement the get(long)
and
set(long, Object)
methods that are used by accessors to access
pixels.- Author:

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.
- Returns:
- fast iterating iterator
-
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.
- Returns:
- fast localizing iterator
-
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:RandomAccessibleInterval
s have a finite domain (theirInterval
), soRandomAccessible.randomAccess()
is only guaranteed to cover this finite domain. This may lead to unexpected results when usingViews
. In the following codeRandomAccessible<T> extended = Views.extendBorder( img ) RandomAccessibleInterval<T> cropped = Views.interval( extended, img ); RandomAccess<T> a1 = extended.randomAccess(); RandomAccess<T> a2 = cropped.randomAccess();
Theaccess
a1
on the extended image is valid everywhere. However, somewhat counter-intuitively, theaccess
a2
on the extended and cropped image is only valid on the intervalimg
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 theRandomAccessibleInterval
, and you know that theRandomAccessibleInterval
is actually defined beyond its interval boundaries, then use theRandomAccessible.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.- Returns:
- random access sampler
-
iterationOrder
Description copied from interface:IterableRealInterval
Returns the iteration order of thisIterableRealInterval
. If the returned object equals (Object.equals(Object)
) the iteration order of anotherIterableRealInterval
f then they can be copied by synchronous iteration. That is, having anIterator
on this and anotherIterator
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.- Returns:
- the iteration order of this
IterableRealInterval
