3.4.3 Implementing collections

Interfaces that support the Collection protocol can be implemented using the macro define-automation-collection. This defines a subclass of standard-automation-collection, which implements the minimal set of collection methods and calls Lisp functions to provide the items. If the collection items are interface pointers, appropriate reference counting must be observed.

See the example in the directory examples/com/automation/collections/ .
