What are containers?

How do I use gFTL?

quick tutorial

Containers currently supported by gFTL:

• vector
• set and altSet
• map

Compiler support

• Intel ifort 18.0.3
• GNU gfortran 8.2
• NAG nagfor 6.2

OS support

• Linux
• OS X

Nifty features

• gFTL supports containers of elements that have POINTER or ALLOCATABLE attributes
• gFTL supports containers of fixed size arrays
• gFTL supports containers of deferred shape arrays
• gFTL supports containers of (allocatable or pointer) polymorphic elements ** pointers to elements in such containers are robust even on insertion and deletion of (other) elements
• Robust pointers with polymorphic elements
• Known compiler bugs
• map

Gotchas

• If you define a container in 2 locations, Fortran considers them separate types. Even if spelled the exactly the same. So, if you want to share a container across multiple software components, be sure to declare it in some shared module that can be accessed accordingly. (And see gFTL-shared below.)
• Known compiler bugs
• You need to #define _alt when using map containers. This may change someday.
