Module Stdlib.Oo
Contents
Instructions: Use this module in your project
In the IDE (CLion, Visual Studio Code, Xcode, etc.) you use for your DkSDK project:
Add the following to your project's
dependencies/CMakeLists.txt:DkSDKProject_DeclareAvailable(ocaml CONSTRAINT "= 4.14.0" FINDLIBS str unix runtime_events threads dynlink) DkSDKProject_MakeAvailable(ocaml)Add the
Findlib::ocamllibrary to any desired targets insrc/*/CMakeLists.txt:target_link_libraries(YourPackage_YourLibraryName # ... existing libraries, if any ... Findlib::ocaml)Click your IDE's
Buildbutton
Not using DkSDK?
FIRST, do one or all of the following:
Run:
opam install ocaml.4.14.0Edit your
dune-projectand add:(package (name YourExistingPackage) (depends ; ... existing dependenices ... (ocaml (>= 4.14.0))))Then run:
dune build *.opam # if this fails, run: dune buildEdit your
<package>.opamfile and add:depends: [ # ... existing dependencies ... "ocaml" {>= "4.14.0"} ]Then run:
opam install . --deps-only
FINALLY, add the library to any desired (library)and/or (executable) targets in your **/dune files:
(library
(name YourLibrary)
; ... existing library options ...
(libraries
; ... existing libraries ...
))
(executable
(name YourExecutable)
; ... existing executable options ...
(libraries
; ... existing libraries ...
))valcopy : ``< .. >``as'a->'a
Oo.copy o returns a copy of object o, that is a fresh object with
the same methods and instance variables as o.
valid : ``< .. >``->int
Return an integer identifying this object, unique for the current execution of the program. The generic comparison and hashing functions are based on this integer. When an object is obtained by unmarshaling, the id is refreshed, and thus different from the original object. As a consequence, the internal invariants of data structures such as hash table or sets containing objects are broken after unmarshaling the data structures.
