Class PEP249 :: Connection :: InstanceSource
A source of database connections (following PEP 249), extend this class to model new instances.
This can include instantiations of the class, return values from function calls, or a special parameter that will be set when functions are called by external libraries.
Use the predicate Connection::instance() to get references to database connections (following PEP 249).
Extend this class if the module implementing PEP 249 offers more direct ways to obtain
a connection than going through connect.
