algorithm - Data range filters in C++ -

-

i want allow user able define ranges filter data. ranges defined contiguous, on lapping, or separated (e.g. user enters following ranges: 1-10, 5-10, 10-12, 7-13, , 15-20).

i want filter data user displayed within ranges.

i create code on different layer combine ranges appropriate (so above example become 1-13 , 15-20, don't want data service concerned that, must able handle example above)

i have lot of data , speed priority, don't want have iterate through list of ranges each data item check if should displayed user or not.

is there data structure (or algorithm) used achieve this?

you can use boost's filter_iterator achieve this.

unit testing - How to mock PreferenceManager in Android? -

-
i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
