===== Description =====
The class ''ADOdbLoadBalancer'' is the parent class for the ADOdb Load Balancer plugin. Its primary function is to manage database connections that have been accumulated via instantiations of the  [[v5:reference:loadbalancer:adodbloadbalancerconnection|ADOdbLoadBalancerConnection]] class, and intercept calls made through an ADOdb database connection.
===== Usage =====
<code php>
$db = new ADOdbLoadBalancer;
</code>
Note that the class cannot itself create a database connection. The connection is made through the ADOdbLoadBalancer class

<code php>
$db = new ADOdbLoadBalancer;

$db0 = new ADOdbLoadBalancerConnection($params.....)
$db->addConnection($db0);

$SQL = "SOME SQL Statement";
$db->execute($SQL);
</code>

The load balancer provides a drop-in replacement for the ''newADOConnection'' method, and supports the execution of all commands in the ADOdb library.
