Package com.fizzed.crux.util

Class MaybeStream<T>

java.lang.Object

com.fizzed.crux.util.MaybeStream<T>

Type Parameters:

T - The type of Maybe

All Implemented Interfaces:

java.lang.Iterable<T>

public class MaybeStream<T>
extends java.lang.Object
implements java.lang.Iterable<T>

A null-safe way of working with iterables and arrays as streams. Useful for iterating with indexes too :-)
