factory.js 

        angular.module("app").factory('geotreefactory', function() {             return {   gettreecheck: function (geolocation) {       if (geolocation.id === 5657){         $.each(geolocation.parent(),function(index,location) {           if (location.id !== geolocation.id) {             $.each(location._childrenoptions.data.items,function(index,child){               var disablechildid = 'disabled' + child.id;               var model = $parse(disablechildid);                 model.assign($scope, true);             })             var disableitemid = 'disabled' + location.id;             var model = $parse(disableitemid);             model.assign($scope, true);           }         });       }       // if child checked disable parents       try {           var parent = geolocation.parent().parent();           var disableparentid = 'disabled' + parent.id;           var parentmodel = $parse(disableparentid);           parentmodel.assign($scope, true);       } catch (err) {      // ignore since happens when node selected has no children          }      //expand , collapse tree on parent check childrens can disabled.       $scope.riskinprcsgeolocationtree.expand($scope.riskinprcsgeolocationtree.findbytext(geolocation.text));       $scope.riskinprcsgeolocationtree.collapse($scope.riskinprcsgeolocationtree.findbytext(geolocation.text));       //if parent item checked, disable children       if(geolocation.items) {           $.each(geolocation.items,function(index,location) {             var disableitemid = 'disabled' + location.id;             var model = $parse(disableitemid);             model.assign($scope, true);           });       }        },        //else block function if ocnditions false       gettreeuncheck: function(geolocation) {         if (geolocation.id === 5657){           var getparent = geolocation.parent();           $.each(geolocation.parent(),function(index,location) {             if (location.id !== geolocation.id) {               $.each(location._childrenoptions.data.items,function(index,child){                 var disablechildid = 'disabled' + child.id;                 var model = $parse(disablechildid);                   model.assign($scope, false);               })               var disableitemid = 'disabled' + location.id;               var model = $parse(disableitemid);               model.assign($scope, false);             }           });         }         // if child unchecked enable parent         try {           var parent = geolocation.parent().parent();           var checkedchildrens = [];           (var i=0; i<selectedriskgeolocations.length; i++){             var checknodes = selectedriskgeolocations[i];             checkedchildrens.push(checknodes);           }           if (checkedchildrens.length === 0){             var disableparentid = 'disabled' + parent.id;             var parentmodel = $parse(disableparentid);             parentmodel.assign($scope, false);           };       }         catch (err) {           // ignore since happens when node selected has no children          }         //if parent item unchecked,  enable childrens         if(geolocation.items){             $.each(geolocation.items,function(index,location){               var disableitemid = 'disabled' + location.id;               var model = $parse(disableitemid);               model.assign($scope, false);             });         }       } };

controller.js

var selectedctlgeolocations = [];                     var selectedctlgeolocationids = [];                     $scope.populatecontrolinprcsgeoloction = function(geolocation) {                         var pos = $.inarray(geolocation.text,selectedctlgeolocations);                         if (pos < 0) {                             selectedctlgeolocations.push(geolocation.text);                             selectedctlgeolocationids.push(geolocation.id);                              // if parent item checked, disable                             // children                          geotreefactory.gettreeifblock();                          } else {                             selectedctlgeolocations.splice(pos, 1);                             selectedctlgeolocationids.splice($.inarray(                                     geolocation.id, selectedctlgeolocationids),                                     1);                              // if parent item unchecked, enable                             // children                             geotreefactory.gettreeelseblock();                         }                      };

alright, way off here, you're trying do?

app.factory('myservice', function(){   return {     ifblock: function(){       // code run if condition true     },     elseblock: function(){       // code run if condition false     }   } });  app.controller('main', function(myservice){   $scope.myevent = function(geolocation){     if(condition){       myservice.ifblock(geolocation);     } else {       myservice.elseblock(geolocation);     }   } });

you solve problem (and if understand problem correctly, preferred method):

app.service('myservice', function(){   return {     go: function(geolocation){       if(condition){         // code run if condition true       } else {         // code run if condition false       }     }   } });  app.controller('main', function(myservice){   $scope.myevent = function(geolocation){     myservice.go(goelocation);   } });

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
