/**
* <p>Encapsulates all the configuration information required by a c3p0 pooled DataSource.</p>
*
* <p>Newly constructed PoolConfig objects are preset with default values,
* which you can define yourself (see below),
* or you can rely on c3p0's built-in defaults. Just create a PoolConfig object, and change only the
* properties you care about. Then pass it to the {@link com.mchange.v2.c3p0.DataSources#pooledDataSource(javax.sql.DataSource, com.mchange.v2.c3p0.PoolConfig)}
* method, and you're off!</p>
*
* <p>For those interested in the details, configuration properties can be specified in several ways:</p>
* <ol>
* <li>Any property can be set explicitly by calling the corresponding method on a PoolConfig object.</li>
* <li>Any property will default to a value defined by a System Property, using the property name shown the table below.</li>
* <li>Any property not set in either of the above ways will default to a value found in a user-supplied Java properties file,
* which may be placed in the resource path of
* the ClassLoader that loaded the c3p0 libraries under the name <tt>/c3p0.properties</tt>.</li>
* <li>Any property not set in any of the above ways will be defined according c3p0's built-in defaults.</li>
* </ol>
*
* <p><i>Please see c3p0's main documentation for a description of all available parameters.</i></p>
*
* @deprecated as of c3p0-0.9.1. To manipulate config programmaticall, please use ComboPooledDataSource
