javascript - Strict parameter matching in backbone.js router -

-

i've got router defined such:

var myrouter = backbone.router.extend({   routes: {     // catch-all undefined routes     "*notfound" : "notfound",   },    initialize: function(options) {     this.route("my_resource/clear_filters", 'clearfilters');     this.route("my_resource/:id", 'show');   },    show: function(id){     console.log('show', id);   },    clearfilters: function() {     console.log('clearfilters');   },    notfound: function() {     console.log('notfound');   }, });  var app = {}; app.myrouter = new myrouter(); backbone.history.start({silent: true});

thus following urls map as:

var opts = {trigger: true}; app.myrouter.navigate('/foo', opts);                       // logged -> 'notfound' app.myrouter.navigate('/my_resource/123', opts);           // logged -> 'show', '123' app.myrouter.navigate('/my_resource/clear_filters', opts); // logged -> 'clearfilters' app.myrouter.navigate('/my_resource/some_thing', opts);    // logged -> 'show', 'some_thing'

how can restrict my_resource/:id route match on numeric parameters app.myrouter.navigate('/my_resource/some_thing') handled notfound?

from fine manual:

route router.route(route, name, [callback])

manually create route router, route argument may routing string or regular expression. each matching capture route or regular expression passed argument callback.

so can things like:

this.route(/my_resource\/(\d+)/, 'show')

in router's initialize if need finer grained control on routes backbone's string patterns give you.

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.
