FAQ: What is a Singleton and Where Can I Find a List of ArcGIS Singleton Objects?

A singleton is a software design pattern that restricts the instantiation of an object to only one class. In ArcObjects, singleton objects require instantiation through the Activator class and require explicit release by way of the ComReleaser class. See Singleton Objects for a complete listing.
