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.
