emptyIterable

public static <E> Matcher<Iterable<? extends E>> emptyIterable()

Creates a matcher for Iterables matching examined iterables that yield no items.

For example:

assertThat(new ArrayList<String>(), is(emptyIterable()))

emptyIterableOf

public static <E> Matcher<Iterable<E>> emptyIterableOf(Class<E> unusedToForceReturnType)

Creates a matcher for Iterables matching examined iterables that yield no items.

For example:

assertThat(new ArrayList<String>(), is(emptyIterableOf(String.class)))

Parameters:

unusedToForceReturnType - the type of the iterable's content
