Re: [Help-glpk] Gplk and exception handling

[Heinrich Schuchardt]

Hello Sylvain,

if an internal error occurs in GLPK for Java it calls glp_free_env() 
before throwing GlpkException. This frees (and invalidates) all memory 
allocated by the GLPK library.

The exception will not free memory allocated by
- new_doubleArray
- new_intArray

For these you have to call the delete methods
- delete_doubleArray
- delete_intArray.

Garbage collection will neither free said arrays nor any memory assigned 
by the GLPK library.

Best regards

Heinrich Schuchardt
