Re: [Help-glpk] Gplk and exception handling

[Sylvain Fournier]

Hello Heinrich,

Rabih talked about garbage collection. I'd like to know if GLPK for Java handles garbage collection and automatically deletes the problem object in C (either in case of exception or in a normal run) or if it must be done by hand.

If GLPK for Java handles garbage collection, could you tell me since which version?

Thanks!

Hello Rabih,

please have a look at GLPK for Java to see how a decent wrapping can be done.
http://glpk-Java.sf.net

The error handling is in swig/glpk.i

It makes use of the error hook function.
