mixins/single_enumerable_container

module SingleEnumerableContainer

A mixin for containers that are single-enumerable (that is, they do not consist of key/value pairs, but are more analgous to a list of elements).

Public Methods

nitems

Determine the number of non-nil items in the container

Returns: the number of non-nil items found

include?(item)

Determine if a particular value is in a container.

TODO: Does this belong in this mixin? Could a container have O(1) access on values and still be single-enumerable?

Returns: true if the value was found, false otherwise.
