Class Details



	

		
This implementation of the singleton pattern does not conform to the strong definition  given by the "Gang of Four." The __construct() method has not be privatized so that  a singleton pattern is capable of being achieved; however, multiple instantiations are also  possible. This allows the user more freedom with this pattern.
