public interface InjectiveFunction<T,R>
extends java.util.function.Function<T,R>
Function which signals to some implementors that
the function returns distinct values. This can be helpful because when a function is applied to data is ambiguous
if the resulting data produced is distinct or not. This allows some callers of this method to apply additional
performance optimizations taking this into account.
If a function is implemented with this and it doesn't produce distinct values, the operation of the consumer of this function may be undefined.
