Package org.tensorics.core.tensor.resample.impl

Class RepeatingResampler<C,​V>

  • Type Parameters:
    C - the type of the coordinate in whos direction to resample
    V - the type of the tensor values
    All Implemented Interfaces:
    SingleDimensionResampler<C,​V>
    public class RepeatingResampler<C,​V>
extends java.lang.Object
implements SingleDimensionResampler<C,​V>
    Resampler that repeats values in one dimension. It requires a comparator for coordinates of the concerned dimension. If possible, values are repeated from the previous point. If the requested point is before the first point, then the value is 'repeated' from the next point.
