bool test(E element)
) Returns a new lazy Iterable
with all elements that satisfy the
predicate test
.
The matching elements have the same order in the returned iterable
as they have in iterator
.
This method returns a view of the mapped elements. As long as the
returned Iterable
is not iterated over, the supplied function test
will
not be invoked. Iterating will not cache results, and thus iterating
multiple times over the returned Iterable
will invoke the supplied
function test
multiple times on the same element.
