Symfony 1.0.0 : Vue détaillée de ConnectionCommon.php

[Code source] [Imprimer] [Statistiques]

Class that contains some shared/default information for connections. Classes may wish to extend this so as not to worry about the sleep/wakeup methods, etc. In reality this class is not very useful yet, so there's not much incentive for drivers to extend this.

Fonctions

Fonctions qui ne font pas partie d'une Classe:

__sleep() X-Ref

This "magic" method is invoked upon serialize() and works in tandem with the __wakeup()
method to ensure that your database connection is serializable.

This method returns an array containing the names of any members of your class
which need to be serialized in order to allow the class to re-connect to the database
when it is unserialized.

<p>
Developers:

Note that you cannot serialize resources (connection links) and expect them to
be valid when you unserialize. For this reason, you must re-connect to the database in the
__wakeup() method.

It's up to your class implimentation to ensure that the necessary data is serialized.
You probably at least need to serialize:

(1) the DSN array used by connect() method
(2) Any flags that were passed to the connection
(3) Possibly the autocommit state

return: array The class variable names that should be serialized.

__wakeup() X-Ref

This "magic" method is invoked upon unserialize().
This method will re-connects to the database using the information that was
stored using the __sleep() method.

getResource() X-Ref

getDSN() X-Ref

getFlags() X-Ref

prepareCall($sql) X-Ref

Creates a CallableStatement object for calling database stored procedures.

param: string $sql
return: CallableStatement

supportsNestedTrans() X-Ref

Driver classes should override this if they support transactions.

return: boolean

begin() X-Ref

Begins a transaction (if supported).

commit() X-Ref

Commits statements in a transaction.

rollback() X-Ref

Rollback changes in a transaction.

setAutoCommit($bit) X-Ref

Enable/disable automatic commits.

Pushes SQLWarning onto $warnings stack if the autocommit value is being changed mid-transaction. This function
is overridden by driver classes so that they can perform the necessary begin/end transaction SQL.

If auto-commit is being set to TRUE, then the current transaction will be committed immediately.

param: boolean $bit New value for auto commit.
return: void

getAutoCommit() X-Ref

Get auto-commit status.

return: boolean

beginTrans() X-Ref

Begin new transaction.
Driver classes should override this method if they support transactions.

commitTrans() X-Ref

Commit the current transaction.
Driver classes should override this method if they support transactions.

rollbackTrans() X-Ref

Roll back (undo) the current transaction.
Driver classes should override this method if they support transactions.

isConnected() X-Ref

Returns false if connection is closed.

return: boolean
