Create a function which will provide named instances of some
other kind of object. The created function will use the provided
factory to create new instances of those objects. The created
function will always return values provided by the factory; the
resulting instances will vary depending on the name argument
provided to the created function:
- If a name is provided, the resulting instance will be the same instance that was returned the last time the created function was called with that name, except in the case where there is no "last time"; then it will be a new instance.
- If no name is provided, a new "anonymous" instance will be provided. The same instance will never be returned again.
Returns: function - an instantiation function.
