• caching - specifies whether or not caching should be used.
• lifeTime - the lifetime of objects in the cache.
• fileLocking - specifies whether or not file locking should be used.

• readControlType - the type of read control to be used.

Further information on the options array can be obtained from the Cache_Lite website.

Since this is an abstract class, the constructor is not called directly. The class is instantiated by calling the JFactory::getCache method. This method will instantiate the appropriate child class. This constructor is called by the child class using:

parent::_construct( $options );
