java - Adding list item to JList from another JList -

-

i have following code working

made_list.setlistdata(original_list.getselectedvalues());

here made_list 1 jlist , original_list jlist. if run code selected value original_list replacing previous value in made_list. dont want that. want append instead.. how do ??

1) model made_list 2) selected items orig_list 3) make new object[] size of 1) + 2) 4) populate 3) items 1) + 2) 5) set make_list model object[] 4)

implementation:

listmodel made_model = made_list.getmodel(); // 1  object[] orig_sel = orig_list.getselecteditems(); // 2  object[] new_made_model = new object[made_model.size() + orig_sel.length]; // 3  // block 4 int = 0; for(;i < made_model.size(); i++)      new_made_model[i] = made_model.getelementat(i); for(; < new_made_model.length; i++)      new_made_model[i] = orig_sel[i - made_model.size());  made_model.setlistdata(new_made_model); // 5

magically formatted comments change reported line number of javascript errors in browsers; this: //@line n "f" n line number , f file name. unfortunately, //@line appears ungoogleable. know there documentation on feature, , browsers support it?

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
