Implicitly. There is a boolean property continuous on raster datasets and on the basic Raster class, which says whether the raster cell values represent a continuous quantity. Since interpolation makes sense only for continuous raster data, the basic lookup methods will automatically use nearest-neighbor lookup on discrete raster data and bilinear interpolation on continuous raster data.

Explicitly. The lookup methods also have overloaded variants that take an explicit RasterFilter parameter. This is the only way to use bicubic interpolation for lookup. It can also make sense to force nearest-neighbor lookup of continuous data, if performance is more important than accuracy.
