public abstract class Function
extends java.lang.Object

This abstract class is used for describing functions over G -> C where G is Z_N1 x ... x Z_Nk or alternatively G is a finite Abelian group described by (gj,Nj) j=1,...,k. The SFT class uses a Function object for query access to the investigated function.
