values.
It does NOT copy T, just the state of the Sampler
.
Otherwise use T.copy() if available.
Sampler.copy().get() == Sampler.get(), i.e. both hold the same
value, not necessarily the same instance (this is the case for an
ArrayCursor
for example)public RandomAccess<O> copyRandomAccess()

RandomAccessible
The returned random access covers as much of the domain as possible.
Please note:RandomAccessibleInterval
s 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.

RandomAccessible
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.
