java - Performance cost of refactoring similar methods into Strategy pattern? -

i find myself facing lot of similar methods repeating code in projects. general pattern seems (apologies vague code, licensing won't let me provide concrete example): public void modifytype1person() { map<string, ?> parameters = new hashmap<>(); parameters.put("type", "type1"); parameters.put("stringargument", "some name"); editpersonbasedontype(parameters); } public void modifytype2person() { map<string, ?> parameters = new hashmap<>(); parameters.put("type", "type2"); editpersonbasedontype(parameters); } public void modifydefaulttypeperson() { map<string, ?> parameters = new hashmap<>(); parameters.put("type", "othertype"); parameters.put("booleanargument", true); editpersonbasedontype(parameters); } public void editpersonbasedontype(ma...

c# - Returning Data to Previous a ViewModel using Prism Navigation -

-
imagine have 2 views, viewmodel infoviewmodel displays information person , viewmodel searchviewmodel handles searching person , selecting result. i want infoviewmodel able initiate search process result in searchviewmodel telling view infoviewmodel has been selected. potential requirement infoviewmodel can communicate searchviewmodel result unacceptable , user should pick else (this should happen without search result screen disappearing , reappearing) normally easy solve infoviewmodel giving searchviewmodel callback called whenever result selected. callback having return parameter specifying whether result or not searchviewmodel can clean or not. seems prism discourages since, @ least in prism 4.0, there no way navigate object parameter (you pass strings parameters). 1 of workarounds i'm using use service store object parameters can uniquely identified in next view way of string guid. has it's own problems, worse feels prism intentionally designed against doing this. ...

reactjs - In Flux what's the appropriate way for an action in one React component to affect another component? -

-
i'm trying wrap head around facebook's flux... say have app side menu can hidden , shown via button in header. my header 1 component, side menu component. currently header component sets class on html div side menu element gets animated hidden css. what's general idea here? reactjs doesn't care how gets data (how it's data getting passed in or how data should handled across web application). that's flux comes in, creates functional approach on how data handled. data-flow essentially: action -> data store -> component mutation of data happen through calling actions. data stores have listen on actions , mutate data within store. keeps data structure , logic flat. in case, dataflow this: header --> user click --> fires action --> updates store --> side menu listening , responding store change. your case simple example don't need flux. think it's easier if have parent component maintains view state logic, , u...

python - re.sub not working for a particular regex pattern -

-
i using following code : re.sub(inputpattern,outputpattern, currentline) in above code , reading value of outputpattern csv , value : \\1-\\2-\\3-\\4 i reading below : outputpattern = row['prefix_1_wrt_fmt'] i have tried : outputpattern = "'"+ row['prefix_1_wrt_fmt'] +"'" the problem is not treating proper format , if hard code below works fine : re.sub(inputpattern,'\\1-\\2-\\3-\\4', currentline) you need escape backslashes if have literal string. "\\1-\\2-\\3-\\4" if read input don't have that. need change pattern inside csv \1-\2-\3-\4 you use raw string if dislike escaping every char when using literal string, prefixing string letter r. r"\1-\2-\3-\4"

from understanding crypt(string, salt), takes salt, tacks onto front of encrypted version of string parameter. $pw = "secret"; $format_and_salt = $2y$10$mwrmztkwmtc5zgjjzdi1nt; $hash = crypt($pw, $format_and_salt); $hash gets stored database column hashed_password $2y$10$mwrmztkwmtc5zgjjzdi1nofgsqugiu7ezetpe.uhjgqbmdrw2.vqm or broken down: first part $format_and_salt: $2y$10$mwrmztkwmtc5zgjjzdi1n (sans 't') + second part encrypted $pw: ofgsqugiu7ezetpe.uhjgqbmdrw2.vqm if use crypt again validate password user submits $_post against stored hashed_password in database, output both cases doesn't seem reflect logic described above. i'm missing something. so then: $existing_hash = $admin['hashed_password'] ($admin being array derived query). and crypt($pw, $existing_hash) returns $2y$10$mwrmztkwmtc5zgjjzdi1nofgsqugiu7ezetpe.uhjgqbmdrw2.vqm which identical $hash above. works validate or invalidate users submission $_post, me...
