Description

An instance of this class is a filter object that discards the first n lines passed to it as input and outputs any following lines unchanged. The number of lines n to output is specified when the Drop filter is constructed. If n is zero, no lines are discarded and all of the lines input to the Drop filter are output unchanged; if there are fewer than n lines input to a Drop filter then none of the lines input to it are output.
