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.

                                                       throws StandardException
Get a new LanguageConnectionContext. this holds things we want to remember about activity in the language system, where this factory holds things that are pretty stable, like other factories.

The returned LanguageConnectionContext is intended for use only by the connection that requested it.

Returns:
a language connection context for the context stack.
Throws:
StandardException - the usual
