public abstract class ProtocolImporter

The abstract ProtocolImporter class and its concrete derived classes generate client proxy code or abstract server code according to a specified communication protocol. ProtocolImporter provides common functionality regardless of the protocol. Within a given protocol, a concrete derived class generates a class for each supported binding defined in a Web Services Description Language (WSDL) document. Typically, instead of directly invoking classes derived from ProtocolImporter, a developer uses these classes indirectly through the ServiceDescriptionImporter class.
