Method Details

andThen

@BetaApi
public RangeSpecFunction andThen(RangeSpecFunction then)

Returns a composed function that first applies this function to its input, and then applies the then function to the result.

Both functions will be called with the same offset.

The returned instance is equivalent to the following:

 then.apply(offset, this.apply(offset, prev))
