I box my numeric primitives using a macro:
#define DB_BOX_INT64( x ) ( mono_value_box(mono_domain_get(),
mono_get_int64_class(), &x) )
And use it like so:
1.
- (void)box
{
MonoObject *monoObject = DB_BOX_INT64(value);
}
I save the MonoObject * into a local variable. The collector will see the
object on the stack and collect it only when the enclosing function completes.
2.
- (void)box:(long long)value
{
self.monoObject = DB_BOX_INT64(value);
self.gcHandle = mono_gchandle_new(self.monoObject, FALSE);
}
- (void)dealloc
{
mono_gchandle_free(self.gcHandle);
}
I save the MonoObject * into an instance variable. The collector will free the
MonoObject after the call to mono_gchandle_free().
Is the above correct?
Regards
Jonathan
