is there way in spring data dynamically form clause? what want have method (which findby / method) runs , and using mentioned properties not null. for example, consider object person [firstname, lastname, age, gender] our method looks this findby_ifnotnullfirstname_andifnotnulllastname_andifnotnullage_andifnotnullgender(string firstname, string lastname, integer age, string gender) thanks. take @ jpa specification , predicate, , better querydsl, there both supported spring data repositories. article provide example: http://spring.io/blog/2011/04/26/advanced-spring-data-jpa-specifications-and-querydsl/

i preparing new version of 1 of apps, , made such huge changes in app, need data conversion after update of app absolutely first thing (before doing else). figured out, best place in class (which extends application) in oncreate() method. tested few times, , seems work ok, read documentation: base class need maintain global application state. can provide own implementation specifying name in androidmanifest.xml's tag, [b]which cause class instantiated when process application/package created[/b]. it looks right, not quite sure. can confirm/disprove it? the application constructor called first. application::oncreate() method called. exception know of if application contains contentprovider, can receive calls before application does. this here: http://developer.android.com/reference/android/app/application.html#oncreate() public void oncreate () added in api level 1 called when application starting, before activity, service, or rece...

i have got simple coredata entity "myentity" recursive relationship: (the relation one-to-one relation in case) imagine had created 5 objects of entity: objecta -> objectb -> objectc -> objectd -> objecte ( objectb child of objecta , on) i create nsfetchrequest nssortdescriptors return objects in correct order (from root last child): objecta objectb objectc objectd objecte is possible? (my specific problem more complex, think can done if got simple 1 solved) why bother, fetch parent object , it's child , child's child property (relationship) directly. if need them in array use while loop traverse hierarchy until child = nil.

in pandas dataframe, when writing csv can encode file adding argument encoding='utf-8' however there issue this. if getting data directly database , placing directly dataframe, when writing csv, encoding error: unicodeencodeerror: 'ascii' codec can't encode characters in position 24-25: ordinal not in range(128) so decoding/encoding needs happen prior placing data datframe. does have simple solution this? if creating dataframe database, can use read_sql : df = pd.read_sql('select * foo', con) here con connection object, e.g. created using sqlite3 or mysqldb.

as read in books , in web, in c++ can overload "plus" or "minus" operators these prototypes (as member functions of class money ): const money operator +(const money& m2) const; const money operator -(const money& m2) const; and assignment operator with: const money& operator =(const money& m2); why use reference money object return value in assignment operator overloading , not in plus , minus operators? returning reference assignment allows chaining: a = b = c; // shorter equivalent "b = c; = b;" (this work (in cases) if operator returned copy of new value, that's less efficient.) we can't return reference arithmetic operations, since produce new value. (sensible) way return new value return value. returning constant value, example does, prevents move semantics, don't that.
