public class AdapterFactoryDescriptorMap
extends java.util.TreeMap<AdapterFactoryDescriptorKey,AdapterFactoryDescriptor>

The AdapterFactoryDescriptorMap is a sorted map of AdapterFactoryDescriptor instances indexed (and ordered) by their AdapterFactoryDescriptorKey. This map is used to organize the registered AdapterFactory services for a given adaptable type.

Each entry in the map is a AdapterFactoryDescriptor thus enabling the registration of multiple factories for the same (adaptable, adapter) type tuple. Of course only the first entry (this is the reason for having a sorted map) for such a given tuple is actually being used. If that first instance is removed the eventual second instance may actually be used instead.
