I am new to the android data binding and I was looking at the code which says, as bellow

 @get:Bindable
    var userIds: MutableList<Long> = mutableListOf()
        private set(value) {
            field = value
            notifyPropertyChanged(BR.userIds)
so, what is the @get:Bindable does here. Is the @Bindable and @get:Bindable same?
Below two are identical to each other. Or you can say two ways to put annotation on getter.
@get:Bindable
    var userIds: MutableList<Long> = mutableListOf()
        private set(value) {
            field = value
            notifyPropertyChanged(BR.userIds)
var userIds: MutableList<Long> = mutableListOf()
    @Bindable get() = _title
    set(value) {
        field = value
        notifyPropertyChanged(BR.userIds)
For understanding more clearly in Java, it is identical to below.
private ArrayList<Long> userIds = new ArrayList<>();
@Bindable
public ArrayList<Long> getUserIds() {
    return userIds;
public void setUserIds(ArrayList<Long> userIds) {
    this.userIds = userIds;
    notifyPropertyChanged(BR.selected);
You can understand more about Annotations on official doc.
