A set of related classes and subclasses that represent the physical and conceptual entities in your application. You structure the classes hierarchically to determine which classes inherit their definitions from which other classes. See also inheritance.
Each class, except the base class, is derived from some other class. The tree structure determined by the derived-class/superclass relationships among all of the classes is called the class hierarchy. The class hierarchy should not be confused with the child/parent hierarchy.
a set of classes that build on top of each other using inheritance and virtual functions)
A set of classes related by inheritance. Succeeding descendant levels extend from general to specific behavior.
The abstract hierarchy of widget classes in Motif. Class hierarchy is distinguished from design hierarchy.
a tree structure that represents the inheritance relationship among a set of classes.
A directed acyclic graph (DAG) that describes the subclass/superclass relationships among classes. Each node represents a class, the children of a node represent the direct subclasses of a class, and the parents of a node represent the direct superclasses of a class.
A tree structure that defines the relationships between classes. A class has subclasses down the hierarchy from itself and superclasses up the hierarchy from itself. The methods and variables of a class are inherited by its subclasses.
A characterization of the generalization/specialization relationships between classes. A class hierarchy is typically shown as a tree (directed acyclic graph) for single inheritance or a lattice for multiple inheritance. The nodes represent classes and are connected by arcs to indicate inheritance relations.
The relationships between all of the widget classes.
tree structure that defines relationships among classes; each class hierarchy has a single top node and potentially many nodes under the top node, along different branches; a child class on the hierarchy inherits the parent class's variables and methods
The structure formed by the inheritance relationships among class es. The hierarchy of classes is rooted in the class Object, which defines the state and behavior common to all object s in the system. Class Object does not inherit from any other class.
A collection of classes organised by generalisation relationships.
As in taxonomy, the classifications of species, a class hierarchy in computer science is a classification of object types, denoting objects as the instantiations of classes (class is like a blueprint, the object is what is built from that blueprint) inter-relating the various classes by relationships such as "inherits", "extends", "is an abstraction of", "an interface definition".
