The ability of a solid material to exist in more than one form or crystal structure; pleomorphism
a difference in DNA sequence among individuals Genetic variations occurring in more than 1% of a population can be used for genetic linkage analysis
allows classes with a sufficiently similar interface to substitute for one another This allows, for example, a new kind of clean deconvolution to be introduced without having to change any client code that needs such deconvolution
Polymorphism allows a subclass to override the operation that it inherits from its superclass sequence A sequence is an array, which can have unbounded dimensions A simple sequence would be a one-dimensional, unbounded list
(chemistry) the existence of different kinds of crystal of the same chemical compound
different crystal structures at different temperatures or pressures for a single compound
The ability to define a base class that includes routines that perform standard operations on groups of related objects without worrying about the exact data type of the object
The coexistence, in the same locality, of two or more distinct forms independent of sex, not connected by intermediate gradations, but produced from common parents
the way multiple subclasses can respond differently to the same message (declared in the superclass) (Polymorphism - Slide 3)
(biology) the existence of two or more forms of individuals within the same animal species (independent of sex differences)
Discontinuous genetic variation that results in the occurrence of several different forms or types of individuals among the members of a single species. The most obvious example of polymorphism is the separation of most higher organisms into male and female sexes. Another example is the different blood types in humans. A polymorphism that persists over many generations is usually maintained because no one form has an overall advantage or disadvantage over the others in terms of natural selection. Some polymorphisms have no visible manifestations. The castes that occur in social insects are a special form of polymorphism that results from differences in nutrition rather than from genetic variation
Difference in DNA sequence among individuals that may underlie differences in health Genetic variations occurring in more than 1% of a population would be considered useful polymorphisms for genetic linkage analysis See also: mutation
Polymorphism is the ability of different objects to respond differently to the same message
Difference in DNA sequence among individuals Genetic variations occurring in more than 1% of a population would be considered useful polymorphisms for genetic linkage analysis Compare mutation
The ability of an object reference to be used as if it referred to an object with different forms Polymorphism in Java results from both class inheritance and interface inheritance The apparently different forms often result from the static type of the variable in which the reference is stored Given the following class header class Rectangle extends Polygon implements Comparable an object whose dynamic type is Rectangle can behave as all of the following types: Rectangle, Polygon, Comparable, Object
The ability of different object to respond to the same message in specific ways: Objects can have very different implementations of the same message In Smalltalk polymorphic behaviour in responce to messages is independent of inheritance
