Note that this class has no direct connection to the server, + * all of it's information is simply determined by way of version comparisons using hard coded values of known + * versions and the functionality they support. + * + * Every new MySQL connection that is established should create an instance of this class and make it globally + * accessible to the rest of the application to remove the need of manual version comparisons. Calling it's + * designated initializer (initWithMajorVersion:major:minor:release:) causes the determination of what + * functionality is supported, and so other initializtion is required. + * + * See the method evaluate for information regarding adding additional functionality checks. + */ +@interface SPServerSupport : NSObject +{ + // Convenience vars + BOOL isMySQL3;
