How to use onSavedInstanceState example please
I'm confused when it comes down to saving a state. So I know that onSaveInstanceState(Bundle) is called when the activity is about to be destroyed.

Equals(=) vs. LIKE
...cifiers of P.
(Emphasis added.)
This is pretty wordy, so let's break it down. Items ii and iii refer to the wildcards _ and %, respectively. If P does not contain any wildcards, then only item iv applies. This is the case of interest posed by the OP.

.pipe(c)
.on('error', function(e){handleError(e)});
