java - Where to add code which filters results returned from Spring service -



java - Where to add code which filters results returned from Spring service -

in spring controller receiving list of items service , using custom code within controller create new filtered list subset of list retured service.

i don't think filtering code should take place in controller ?

here controller :

@controller public class mycontroller { @autowired private myservice myservice; @rendermapping public string getvalues(modelmap modelmap){ list<string> = myservice.getnewvalues(); list<string> filteredlist = ...... /** code here process list , convert specific list */ modelmap.addattribute("values", filteredlist); } }

should filtering take place @ service implementation layer ?

so instead of myservice.getnewvalues(); should utilize new method filters results : myservice.getnewfilteredvalues(); ?

note : method myservice.getnewfilteredvalues() new method , contain same code filtering code specified in mycontroller

personally expose myservice.getvalues(); , allow service hide filtering , other logic caller.

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
