javascript - How can I return only filtered model in Emberjs? -

-

i have ember.select filters model based on roles. @ moment, when app initiates full contents of model shown want show model when filters applied. clueless on how gonna that.

here's controller in question,

app.twodcontroller = ember.arraycontroller.extend({     //filteredcontent : null,     sortproperties: ['firstname'],     sortascending: true,     selectedexperience : null,     experience : [{         exp : "1"     }, {         exp : "2"     }, {         exp : "3"     }, {         exp : "4"     }, {         exp : "5"     }],     selecteddesignation : null,     filterdesignation : function() {         var designation = this.get('selecteddesignation.designation');         var filtered = this.get('content').filterproperty('designation', designation);         this.set("filteredcontent", filtered);     }.observes('selecteddesignation'),     designations : [{         designation : "design",         id : 1     }, {         designation : "writer",         id : 2     }, {         designation : "script",         id : 3     }, {         designation : "storyboard",         id : 4     }, {         designation : "workbook",         id : 5     }],     actions : {         filterexperience : function() {             var experience = this.get('selectedexperience.exp');             var filtered = this.get('content').filterproperty('experience', experience);             this.set("filteredcontent", filtered);         },         refresh : function() {             var refresh = this.get('content');             this.set("filteredcontent", refresh);         }     },     filteredcontent : function() {         var searchtext = this.get('searchtext'), regex = new regexp(searchtext, 'i');          return this.get('model').filter(function(item) {             var fullname = item.firstname + item.lastname;             return regex.test(fullname);         });     }.property('searchtext', 'model')  });

moreover, 1 more issue having not able sort ascending order. changes need in code achieve desired result?

here's full jsbin if anyone's interested.

in app.twodcontroller include:

init: function() {   this.set('filteredcontent', []); },

and in filterdesignation change this.get('content') this.get('arrangedcontent') per the ember.sortablemixin documentation.

filterdesignation : function() {     var designation = this.get('selecteddesignation.designation');     var filtered = this.get('arrangedcontent').filterproperty('designation', designation);     this.set("filteredcontent", filtered); }.observes('selecteddesignation'),

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
