I study the mybatis3.3 sources code and now I have a question：in the XMLMapperBuilder.databaseIdMatchesCurrent()
private boolean databaseIdMatchesCurrent(String id, String databaseId, String requiredDatabaseId) {
if (requiredDatabaseId != null) {
if (!requiredDatabaseId.equals(databaseId)) {
return false;
}
} else {
if (databaseId != null) {
return false;
}
// skip this fragment if there is a previous one with a not null databaseId
if (this.sqlFragments.containsKey(id)) {
XNode context = this.sqlFragments.get(id);
if (context.getStringAttribute("databaseId") != null) {
return false;
}
}
}
return true;
}
if the (requiredDatabaseId == null && databaseId != null) ,then the function will return false.
So the code
if (this.sqlFragments.containsKey(id)) {
XNode context = this.sqlFragments.get(id);
if (context.getStringAttribute("databaseId") != null) {
return false;
}
}
certainly no way to return false and this code is useless.
I just want to questioning: I understand this, right?

This is the onsearch function that searches for all custnum addresses.
onSearch(String text) async {
print(text);
List<Item> itemII = items;
if (text.isNotEmpty) {
List<Item> itemList = [];
for (var item in itemII) {
if (item.custnum == text.toLowerCase().toUpperCase()) {
itemList.add(item);
}
}
setState(() {
searchText = text;
searchitems.clear();
searchitems.addAll(itemList);
MainPage.searchItemMainPage.addAll(itemList);
if (searchitems.isNotEmpty) {
print({MainPage.searchItemMainPage[0].address});
searchitems[0].address!.sort((a, b) {
if (a.for_bill == 'Y' && b.for_bill == 'N') {
return -1;
} else if (a.for_bill == 'N' && b.for_bill == 'Y') {
return 1;
} else if (a.for_ship == 'Y' && b.for_ship == 'N') {
return -1;
} else if (a.for_ship == 'N' && b.for_ship == 'Y') {
return 1;
} else if (a.for_contact == 'Y' && b.for_contact == 'N') {
return -1;
} else if (a.for_contact == 'N' && b.for_contact == 'Y') {
return 1;
} else {
return 0;
}
});
}
});
} else {
setState(() {
searchCus.clear();
searchitems.clear();
MainPage.searchItemMainPage.clear();
// searchitems.addAll(items);
print('searchitems : $searchitems');
});
}
}
This is the onsearchaddr function, it finds the address in searchitems after the search. By typing the name of the field addr, then the address will be displayed.
onSearchAddr(String text) {
List<Item> result = searchitems;
if (text.isNotEmpty) {
List<Item> itemList = [];
for (var item in result) {
item.address = item.address!
.where((element) =>
element.addr1!.toUpperCase().toLowerCase().contains(text))
.toList();
itemList.add(item);
}
setState(() {
searchitems.clear();
searchitems.addAll(itemList);
print('itemList : ${itemList}');
});
} else {
setState(() {
searchitems.clear();
searchitems.addAll(MainPage.searchItemMainPage);
print(
'SearchitemsMainPage : ${MainPage.searchItemMainPage[0].address}');
});
}
}
Could you please write some code to modify onsearchaddr, it can search as typed but when it clears text it doesn't show information of searchitems as before but it shows information of last typed message.
It's like the previous backup wasn't provided.
how can I make the logic so when I press vegan and lactose it will show me a meal that contains at least one of them or both?
in the current state it shows only meals that contains both.
Map<String, bool> _filters = {
'gluten': false,
'lactose': false,
'vegan': false,
'vegetarian': false,
};
//above is a switchTile so the values change
_availableMeals = DUMMY_MEALS.where((meal) {
if (_filters['gluten']! && !meal.isGlutenFree) {
return false;
}
if (_filters['lactose']! && !meal.isLactoseFree) {
return false;
}
if (_filters['vegan']! && !meal.isVegan) {
return false;
}
if (_filters['vegetarian']! && !meal.isVegetarian) {
return false;
}
return true;
}).toList();
Here you go. Part of the problem was that you were using ! to mean == false
_availableMeals = DUMMY_MEALS.where((meal) {
// actually i'm not sure about this part, try removing it if it doesn't make sense in your UI
if (_filters['gluten'] == false &&
_filters['lactose'] == false &&
_filters['vegan'] == false &&
_filters['vegatarian'] == false) {
return true;
}
if (_filters['gluten'] == true && meal.isGlutenFree) {
return true;
}
if (_filters['lactose'] == true && meal.isLactoseFree) {
return true;
}
if (_filters['vegan'] == true && meal.isVegan) {
return true;
}
if (_filters['vegetarian'] == true && meal.isVegetarian) {
return true;
}
return false;
}).toList();
This Is my coding for mapping data and filter it by subs class:
Hi i have a problem where is my list is null after it mapping the data so can you help me for this solution
void onUserJobListData(Event e) {
Map data = Map.from(e.snapshot.value);
data?.forEach((a, b) {
print("key " + a);
// int i = _jobs.indexWhere((j) => j.jobId == a);
int i = _jobs == null ? 0 : _jobs.indexWhere((j) => j.jobId == a);
if (i >= 0) {
if (b['notification_date'] != null) {
_jobs[i].matchDetail.notificationDate = b['notification_date'];
}
if (b['status_date'] != null) {
_jobs[i].matchDetail.statusDate = b['status_date'];
}
if (b['event_status'] != null) {
_jobs[i].matchDetail.eventStatus = b['event_status'];
}
if (b['notification_status'] != null) {
_jobs[i].matchDetail.notificationStatus = b['notification_status'];
}
if (b['status'] != null) {
_jobs[i].matchDetail.status = b['status'];
}
}
});
print("Apa apa jerr");
jobState.setJobList(_jobs, JobState.USER_JOB);
}`
I'd like to have a function that checks to see if any of the text edit controller fields are null.
I wrote this method below, but I wanted to see if there was a more elegant solution.
bool _nullfieldExists(){
//return a true if any of the textEditController fields are null
if (_textEditControllerNumberPlayers.text == null ){
return true;
}
else if (_textEditControllerSmallBlind.text == null ){
return true;
}
else if (_textEditControllerBigBlind.text == null ){
return true;
}
else if (_textEditControllerAnte.text == null ){
return true;
}
else if (_textEditControllerMyStack.text == null ){
return true;
}
else {
return false;
}
}

Please advise, how to achieve video rotation without any video Frame loss
Thanks In Advance
Lakshmi Priya . K
Worked for couple of days and finally tried to write the rotated video in different target file then i got the video output without any loss and video is also rotated....
Thanks
Lakshmi Priya. K
