/**
|
|
* Doctrine_Connection
|
|
*
|
|
* A wrapper layer on top of PDO / Doctrine_Adapter
|
|
*
|
|
* Doctrine_Connection is the heart of any Doctrine based application.
|
|
*
|
|
* 1. Event listeners
|
|
* An easy to use, pluggable eventlistener architecture. Aspects such as
|
|
* logging, query profiling and caching can be easily implemented through
|
|
* the use of these listeners
|
|
*
|
|
* 2. Lazy-connecting
|
|
* Creating an instance of Doctrine_Connection does not connect
|
|
* to database. Connecting to database is only invoked when actually needed
|
|
* (for example when query() is being called)
|
|
*
|
|
* 3. Convenience methods
|
|
* Doctrine_Connection provides many convenience methods such as fetchAll(), fetchOne() etc.
|
|
*
|
|
* 4. Modular structure
|
|
* Higher level functionality such as schema importing, exporting, sequence handling etc.
|
|
* is divided into modules. For a full list of connection modules see
|
|
* Doctrine_Connection::$_modules

|
|
* Doctrine::DBAL::Connection must have no dependencies on ORM components since
|
|
* it sits one layer below.
|
|
* Right now, this is the unification of these two classes.
