// Sometimes we need to hold on to a C array and keep it alive, but typical
|
|
// SIP code will treat it as a temporary and delete it as soon as the ctor or
|
|
// method call is done. This class can hold a pointer to the array and will
|
|
// delete the array in its dtor, and by making this class be wrappable we can
|
|
// make a PyObject for it that is then owned by some other object, and
|
|
// Python's GC will take care of the delaying the cleanup until it's no longer
|
|
// needed.
