In Java, a type that overrides the definitions of a base type to provide unique behavior.
A derived type is a type whose operations and values are replicas of those of an existing type. The existing type is called the parent type of the derived type.
A user-defined (non-intrinsic) data type that consists of one or more component s. Each component of a derived type is either an intrinsic data type or another derived type.
a record extension if it includes a record extension part, which has the same syntax as a normal record type definition preceded by the reserved word with
a type given a new type but structually same to the original type
A data type that is user-defined and not intrinsic. It requires a type definition to name the type and specify its components (which can be intrinsic or user-defined types). A structure constructor can be used to specify a value of derived type. A component of a structure is referenced using a percent sign (%). Operations on objects of derived types (structures) must be defined by a function with an OPERATOR interface. Assignment for derived types can be defined intrinsically, or be redefined by a subroutine with an ASSIGNMENT interface. Structures can be used as procedure arguments and function results, and can appear in input and output lists. Also called a user-defined type. See also record, the first definition.
type specifier which is defined in terms of an expansion into another type specifier. deftype defines derived types, and there may be other implementation-defined operators which do so as well.
A derived type is a type defined in terms of another type, which is the parent type of the derived type. Each class containing the parent type also contains the derived type. The derived type inherits properties such as components and primitive operations from the parent. A type together with the types derived from it (directly or indirectly) form a derivation class. (14)
A type created from an existing parent type which inherits the primitive operations of its parent. Objects of a derived type can always be converted to a parent type and vice versa.
(n.) a type whose data have components each of which is either of intrinsic type or of another derived type.
A derived type is a type given a new type but structurally the same as the original type. The purpose of this type is create a new type name so that two values can have two distinct types in terms of name. It matters if the type system uses a name equivalence rule but does not matter if the system uses a structural equivalence.
