Class BiotaHandlerFactory

java.lang.Object
  project.biota.biotaInterface.BiotaHandlerFactory

public class BiotaHandlerFactory

extends Object

BiotaHandlerFactory creates a BiotaRequestHandler depending on the type of the resource requested. It creates a BiotaWebRequestHandler when the resource is served via a Biota onboard Web Server, or a BiotaServerRequestHandler if the resource is served via a 4D Server. If the resource's type is not recognized by the provider, it returns a BiotaDefaultHandler that does nothing.

Developers who implement a new BiotaRequestHandler for a different type of resources need to add codes in this class to create an instance of the new handler when the type matches.
