1.1 Singleton (Single Instance) If we think that a class only needs to generate one instance, we will design it as Singleton (single instance mode ). Singleton is the most frequently used mode in our projects,This mode ensures that a class has only one instance and provides a global access point to it.. Singleton is an improved global variable. The description of this mode is simple, but the implementation is complicated. In particular, the life cycl

undetermined data structures, which frees up the coupling between the structure and the operations acting on the structure, so that the set of operations can evolve relatively freely. Each node of the data structure can accept a call from a visitor, which passes in the node object to the Visitor object, which in turn performs the operation of the Node object. Such a process is called "Double dispatch". The node invokes the visitor, passing it in itself, and the visitor executes an algorithm ag

When the subject object changes in state, all the observer objects are notified so that they can automatically update themselves. A software system oft
