Fundamental patterns are one of the types of design patterns. They are termed fundamental as they form the basic building blocks of the other patterns. Most of the other patterns and most modern applications draw on these patterns in one way or another.
Examples of this class of patterns include:
- Delegation pattern: an object outwardly expresses certain behaviour but in reality delegates responsibility
- Functional design: strives for each modular part of a computer program has only one responsibility and performs that with minimum side effects
- Interface pattern: method for structuring programs so that they're simpler to understand
- Proxy pattern: an object functions as an interface to another, typically more complex, object
- Facade pattern: provides a simplified interface to a larger body of code, such as a class library.
- Composite pattern: defines Composite object (e.g. a shape) designed as a composition of one-or-more similar objects (other kinds of shapes/geometries), all exhibiting similar functionality. The Composite object then exposes properties and methods for child objects manipulation as if it were a simple object.
Famous quotes containing the words fundamental and/or pattern:
“Much of what contrives to create critical moments in parenting stems from a fundamental misunderstanding as to what the child is capable of at any given age. If a parent misjudges a child’s limitations as well as his own abilities, the potential exists for unreasonable expectations, frustration, disappointment and an unrealistic belief that what the child really needs is to be punished.”
—Lawrence Balter (20th century)
“A two-week-old infant cries an average of one and a half hours every day. This increases to approximately three hours per day when the child is about six weeks old. By the time children are twelve weeks old, their daily crying has decreased dramatically and averages less than one hour. This same basic pattern of crying is present among children from a wide range of cultures throughout the world. It appears to be wired into the nervous system of our species.”
—Lawrence Kutner (20th century)
