Interface LanguageConnectionFactory
-
- All Known Implementing Classes:
GenericLanguageConnectionFactory
public interface LanguageConnectionFactory
Factory interface for items specific to a connection in the language system. This is expected to be used internally, and so is not in Language.Interface.This Factory provides pointers to other language factories; the LanguageConnectionContext holds more dynamic information, such as prepared statements and whether a commit has occurred or not.
This Factory is for internal items used throughout language during a connection. Things that users need for the Database API are in LanguageFactory in Language.Interface.
This factory returns (and thus starts) all the other per-database language factories. So there might someday be properties as to which ones to start (attributes, say, like level of optimization). If the request is relative to a specific connection, the connection is passed in. Otherwise, they are assumed to be database-wide services.
