T -

Parameters:

iterable -

Returns:

emptyIterable

public static <T> Iterable<T> emptyIterable()

Simple method to return an empty iterable.

Type Parameters:

T -

singletonIterable

public static <T> Iterable<T> singletonIterable(T data)

Creates an iterable with a single value.

Type Parameters:

T -

Parameters:

data -

Returns:

distinct

public static <T> Iterable<T> distinct(Iterable<T> iterable)
