T - public class FloorInterpolator<T> extends Floor<RandomAccess<T>> implements RealRandomAccess<T>
RealRandomAccess to a RandomAccess by nearest floor
interpolation (i.e., the value is sampled at floor(x)).
In ImgLib2, the coordinate of a sample corresponds to the 'center' point
of the sample, i.e. the location at which the sample was acquired. This
scheme is intuitive in both rasters and irregularly samples data but can
trigger confusion when displaying images on a screen with a pixel raster
which, in this scheme, spans the range [-0.5,width-0.5]. In the
screen-friendly alternative scheme, where sample coordinates reference the
top left corner of the pixel rectangle representing a sample the range
covered by an image is [0,width], however, coordinate transfer
functions other than translation and homogeneous scaling generate different
results than in the center-scheme. Rendering an image using
FloorInterpolator means using the top-left-scheme, rendering it
using NearestNeighborInterpolator, NLinearInterpolator, or
LanczosInterpolator means using the center-scheme.

copy in interface Sampler<T>Sampler in the same state accessing the same
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 FloorInterpolator<T> copyRealRandomAccess()
