this confuses me lot. i had 2 fragments, , use fragmenttransaction.replace() swap 2 fragments. state of input controls radiogroup , checkbox preserved when switch other fragments , switch again. . i set break point on oncreateview() of fragment, , every swap seems trigger method , new views created each time. savedinstancebundle null well. since new views created, how state of old views? public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { view v = inflater.inflate(r.layout.fragment_fieldsetup_marking, container, false); // ... return v; } this effect fine app, want know how implemented. where states stored? where android sdk code restore (i can not find in class fragmenttransection).

in f#: [0] = [0] = true in c# or .net bcl in general: structuralcomparisons.equals(new int[] { 0 }, new int[] { 0 }) == false why? postscript: the reason thought had "right" equals because turned out true: var = new { x = 3, y = new { z = -1 } }; var b = new { x = 3, y = new { z = -1 } }; structuralcomparisons.equals(a, b) == true; that's because you're going down object.equals(obja, objb) won't able handle kind of comparison. instead this: structuralcomparisons.structuralequalitycomparer.equals(..., ...)

javascript - Why do we need a new object in bookshelf.js fetch() method? -

-
i'm new node , using bookshelf.js orm current project. documentation of bookshelf.js contains snippet under fetch() method: // select * `books` `isbn-13` = '9780440180296' new book({'isbn-13': '9780440180296'}) .fetch() .then(function(model) { // outputs 'slaughterhouse five' console.log(model.get('title')); }); http://bookshelfjs.org/#model-fetch what confuses me why need create new object here if querying existing record? way bookshelf.js works requires new object created every returned result? this confusing. @ moment there 1 type of object represents both "model" , "query builder". fetch prefills where clause set attributes on model. there plans underway change this. discussion here . instead of writing code above, i'd recommend doing this: // select * `books` `isbn-13` = '9780440180296' book.where({'isbn-13': '9780440180296'}) .fetch() .then(function
