| − | The <code>rwt.protocol.AdapterRegistry</code> object stores all protocol adapters known to the client. A protocol adapter is needed by the clients message processor for all types of targets used in a given [[RAP/Protocol#Protocol_Format|RAP protocol message]]. It basically translates the API of the [[RAP/WebClient#Communication|'virtual' object]] referenced by the protocol message to the API of the actual client object. If a message contains a [[RAP/Protocol#Create|create operation]] for an unkown type (no matching adapter registered), the client will crash.
