Class ParseQuery<T extends ParseObject>


  • public class ParseQuery<T extends ParseObject>
    extends java.lang.Object
    The ParseQuery class defines a query that is used to fetch ParseObjects. The most common use case is finding all objects that match a query through the findInBackground() method, using a FindCallback. For example, this sample code fetches all objects of class "MyClass". It calls a different function depending on whether the fetch succeeded or not.

     ParseQuery<ParseObject> query = ParseQuery.getQuery("MyClass");
     query.findInBackground(new FindCallback<ParseObject>() {
         public void done(List<ParseObject> objects, ParseException e) {
             if (e == null) {
                 objectsWereRetrievedSuccessfully(objects);
             } else {
                 objectRetrievalFailed();
             }
         }
     }
     

    A ParseQuery can also be used to retrieve a single object whose id is known, through the getInBackground(String) method, using a GetCallback. For example, this sample code fetches an object of class "MyClass" and id myId. It calls a different function depending on whether the fetch succeeded or not.

     ParseQuery<ParseObject> query = ParseQuery.getQuery("MyClass");
     query.getInBackground(myId, new GetCallback<ParseObject>() {
         public void done(ParseObject object, ParseException e) {
             if (e == null) {
                 objectWasRetrievedSuccessfully(object);
             } else {
                 objectRetrievalFailed();
             }
         }
     }
     

    A ParseQuery can also be used to count the number of objects that match the query without retrieving all of those objects. For example, this sample code counts the number of objects of the class "MyClass".

     ParseQuery<ParseObject> query = ParseQuery.getQuery("MyClass");
     query.countInBackground(new CountCallback() {
         public void done(int count, ParseException e) {
             if (e == null) {
                 objectsWereCounted(count);
             } else {
                 objectCountFailed();
             }
         }
     }
     

    Using the callback methods is usually preferred because the network operation will not block the calling thread. However, in some cases it may be easier to use the find(), get(String) or count() calls, which do block the calling thread. For example, if your application has already spawned a background task to perform work, that background task could use the blocking calls and avoid the code complexity of callbacks.
