RE: [Swig-user] swig java finalize

[<jf....@de...>]

Yes, I'm adding objects created with SWIG in containers. These =
containers
are cleaned in the C++ code.

I modified the javafilanize so that the objects are not cleaned
automatically. All the objects in my code are deleted with the .delete()
method in a try catch finally bloc or by the c++ code that manages the
containers.

Thank you

Objet=A0: Re: [Swig-user] swig java finalize

I'm interested in why you'd like to do this, if you don't mind me=20
asking.  SWIG should only delete memory it created and therefore not=20
interfere with the memory created in your own C++ code. Are you doing=20
something like creating an object then adding it into a container which=20
your C++ code then manages the memory?

The javafinalize typemap will affect all objects returned to the Java=20
layer and is likely to create leaks unless your C++ code manages all the =

memory created by SWIG. You can target the typemap more appropriately by =

replacing SWIGTYPE with the name of the C++ class.
