Interface IDriver
Interface implemented by all Neevo drivers.
All Neevo drivers must implement this interface, not only
reproduce all it's methods, or they won't be recognised as valid drivers.
If something is not implemented, the method must throw
Neevo\Drivers\ImplementationException. The exception will be catched and Neevo
will decide, what to do next.
If something is not supported by the driver (e.g. number of result rows on
unbuffered queries) the driver should throw Neevo\DriverException.
When the driver needs to rewrite default output of SQL commands, it
must extend Neevo\Parser class. For proper
use, see source
of Neevo\Parser class.
