Prototype Design Pattern Explained With Simple Example: Creational Design Pattern Category
by The Prototype design pattern is used when the objects which needs to be created is of similar types and can be cloned to produce new objects. The main aim of this pattern is to minimize the required cost of creating new object. This design pattern declares an abstract base class which exposes pure virtual clone() member function which is called by the client to get the required object instead of calling “new”. The idea behind this design pattern is to create first object of all prototype classes by the usual method and then for other objects use clone method which will create the new objects by copying the prototype objects.
