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.
public CellLocalizingCursor<T,C> localizingCursor()
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.
public CellRandomAccess<T,C> randomAccess()
RandomAccessibleThe 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.
public CellIterationOrder iterationOrder()
IterableRealIntervalIterableRealInterval. 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.IterableRealInterval.FlatIterationOrderpublic I getCells()
Cells through Cursors and RandomAccesses.public CellGrid getCellGrid()
CellGrid which describes the layout of the
AbstractCellImg. The grid provides the dimensions of the image, the
number of cells in each dimension, and the dimensions of individual
cells.protected void copyDataTo(AbstractCellImg<T,?,?,?> copy)
