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.- Specified by:
randomAccess
in interfaceRandomAccessible<A>
- Returns:
- random access sampler
-
randomAccess
Description copied from interface:RandomAccessible
Create a random access sampler for integer coordinates.The returned random access is intended to be used in the specified interval only. Thus, the RandomAccessible may provide optimized versions. If the interval is completely contained in the domain, the random access is guaranteed to provide the same values as that obtained by
RandomAccessible.randomAccess()
within the interval.- Specified by:
randomAccess
in interfaceRandomAccessible<A>
- Parameters:
interval
- in which interval you intend to use the random access.- Returns:
- random access sampler
-
size
public long size()Description copied from interface:IterableRealInterval
Returns the number of elements in this
Function
.- Specified by:
size
in interfaceIterableRealInterval<A>
- Returns:
- number of elements
-
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.- Specified by:
iterationOrder
in interfaceIterableRealInterval<A>
- Returns:
- the iteration order of this
IterableRealInterval
. - See Also:

iterator
-
firstElement
Description copied from interface:IterableRealInterval
Get the first element of thisIterableRealInterval
. This is a shortcut forcursor().next()
. This can be used to create a new variable of type T usingfirstElement().createVariable()
, which is useful in generic methods to store temporary results, e.g., a running sum over pixels in theIterableRealInterval
.- Specified by:
firstElement
in interfaceIterableRealInterval<A>
- Returns:
- the first element in iteration order.
-
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 interfaceIterableInterval<A>
- Specified by:
cursor
in interfaceIterableRealInterval<A>
- 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.
- Specified by:
localizingCursor
in interfaceIterableInterval<A>
- Specified by:
localizingCursor
in interfaceIterableRealInterval<A>
- Returns:
- fast localizing iterator
