Patterns in programming are like recipes in cooking. They are not ready dishes, but instructions for slicing and dicing products, cooking them, serving them and so forth.
Pattern content As a rule, a pattern description consists of the following:
- a problem that the pattern solves;
- motivation for solving the the problem using the method suggested by the pattern;
- structures of classes comprising the solution;
- an example in one of the programming languages;
- a description of the nuances of pattern implementation in various contexts; relations with other patterns.
