- allows reuse similar to refPtr for wrapping different content.
- additional control for when contents are copied back,
instead of waiting for the adaptor to go out of scope.
Eg,
if (adaptor.active())
{
adaptor.commit();
adaptor.clear();
}
- static ConstPrecisionAdaptor::get method renamed to 'select' as a
better description of its purpose and avoid confusion with
non-static 'get' method.
Was previously only used within GAMGPreconditioner, but even there
it is better just to use the ConstPrecisionAdaptor directly.
