Declarations for Derived Types

A derived-type declaration specifies the properties of objects and functions of derived (user-defined) type.

The derived type must be defined before you can specify objects of that type in a TYPE type declaration.

An object of derived type must not have the PUBLIC attribute if its type is PRIVATE.

A structure constructor specifies values for derived-type objects.

Examples

The following are examples of derived-type declarations:

  TYPE(EMPLOYEE) CONTRACT
  ...
  TYPE(SETS), DIMENSION(:,:), ALLOCATABLE :: SUBSET_1

The following example shows a public type with private components:

  TYPE LIST_ITEMS
    PRIVATE
    ...
    TYPE(LIST_ITEMS), POINTER :: NEXT, PREVIOUS
  END TYPE LIST_ITEMS
