Examples of IntIntFunction

cern.colt.function.IntIntFunction
Interface that represents a function object: a function that takes two arguments and returns a single value.
org.apache.mahout.math.function.IntIntFunction
@deprecated until unit tests are in place. Until this time, this class/interface is unsupported.
