Doubly Linked List for Fortran 2003
Overview
This is a module to introduce a Doubly Linked List feature into Fortran 2003.
Description
The List is based on the Object-Oriented Programming, so the List can treat all types Fortran supports including integer, real, character and derived-type by using the Unlimited Polymorphism feature. The List also provide iterator feature for user's convenience. This iterator allows you to write multiple loop.
Demo
You can try the List by compiling linkedlist.f90 and execute it.
Feature
- written in Fortran 2003 - you may not be staring in envy Java anymore
- based on the Object-Oriented Programming
- treat all types Fortran supports by the Unlimited Polymorphism feature
- provide iterator feature such as Java's List. the procedures next() and hasNext() are also available
Requirement
- Recommended (perhaps necessary) compiler is Intel Fortran Composer XE 2013 update 5 or later.
I am modifying the codes to complete the compilation using PGI Fortran 14.9.
Bugs
Calling subroutines related to remove an item from a list including only one item causes an illegal memory access. if you'd like to remove all items from a list, you can use the clear() subroutine.
