Class RepeatingResampler<C,V>

java.lang.Object

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

RepeatingResampler

public RepeatingResampler(java.util.Comparator<C> comparator)

Constructs a new resampler, given a comparator for the relevant coordinates

Parameters:

comparator - the comparator for the coordinates in question

Method Detail

resample

public V resample(java.util.Set<C> coordinates,
                  java.util.function.Function<C,V> valuesCallback,
                  C coordinate)

Description copied from interface: SingleDimensionResampler

Performs the actual resampling using the provided input.

Specified by:

resample in interface SingleDimensionResampler<C,V>

Parameters:

coordinates - the supporting points, which can be used as input to resample

valuesCallback - a function providing values of type V for all given coordinates

coordinate - the coordinate at which the resampling shall be performed

Returns:

true if the resampling will be possible with the provided input, false if not.

canResample

public boolean canResample(java.util.Set<C> coordinates,
                           C coordinate)

Specified by:

canResample in interface SingleDimensionResampler<C,V>

Parameters:

coordinates - the supporting points, which can be used as input to resample

coordinate - the coordinate at which the resampling shall be performed

Returns:

true if the resampling will be possible with the provided input, false if not.
