AdapterService(配接器)

An adapter service provides access to Adapters. The primary function of an adapter service is to act as an adapter registry. An adapter service will typically provide support creating adapters through the web or for configuring which of available alternate adapter implementations should be used.

An adapter service is placeful, meaning that it exists at a location in the object hierarchy. A well-behaved adapter service will work with other adapter services higher in the object hierarchy, if any, and with the AdapterRegistry.
