    • randomAccess

      public abstract AbstractConvertedRandomAccess<A,B> 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<A>
      Returns:
      random access sampler
    • randomAccess

      public abstract AbstractConvertedRandomAccess<A,B> randomAccess(Interval interval)
      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 interface RandomAccessible<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 interface IterableRealInterval<A>
      Returns:
      number of elements
    • iterationOrder

      public Object 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<A>
      Returns:
      the iteration order of this IterableRealInterval.

    • iterator

      public Iterator<B> iterator()
      Specified by:
      iterator in interface Iterable<A>
    • firstElement

      public B firstElement()
      Description copied from interface: IterableRealInterval
      Get the first element of this IterableRealInterval. This is a shortcut for cursor().next(). This can be used to create a new variable of type T using firstElement().createVariable(), which is useful in generic methods to store temporary results, e.g., a running sum over pixels in the IterableRealInterval.
      Specified by:
      firstElement in interface IterableRealInterval<A>
      Returns:
      the first element in iteration order.
    • cursor

      public abstract AbstractConvertedCursor<A,B> 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<A>
      Specified by:
      cursor in interface IterableRealInterval<A>
      Returns:
      fast iterating iterator
    • localizingCursor

      public abstract AbstractConvertedCursor<A,B> 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<A>
      Specified by:
      localizingCursor in interface IterableRealInterval<A>
      Returns:
      fast localizing iterator
