Parameters:

obj - the iterable-like to check for emptiness

Returns:

emptiness to fill your heart

isIterable

public static boolean isIterable(Object maybeIterable)

Returns:

whether IterableLike can iterate over the given object

of

public static Iterator<Object> of(Object iterable)

Given an iterable object (which may be a iterator, iterable, primitive or reference array), return an iterator over its (possibly boxed) elements.

Returns:

an iterator of the given array's elements
