RealmResults (Realm 5.1.0)

java.lang.Object
- java.util.AbstractCollection<E>
- - java.util.AbstractList<E>
  - - io.realm.RealmResults<E>

Type Parameters:

E - The class of objects in this list.

All Implemented Interfaces:

OrderedRealmCollection<E>, RealmCollection<E>, Iterable<E>, Collection<E>, List<E>
```
public class RealmResults<E>
extends AbstractList<E>
```
This class holds all the matches of a RealmQuery for a given Realm. The objects are not copied from the Realm to the RealmResults list, but are just referenced from the RealmResult instead. This saves memory and increases speed.
RealmResults are live views, which means that if it is on an Looper thread, it will automatically update its query results after a transaction has been committed. If on a non-looper thread, BaseRealm.waitForChange() must be called to update the results.
Updates to RealmObjects from a RealmResults list must be done from within a transaction and the modified objects are persisted to the Realm file during the commit of the transaction.
A RealmResults object cannot be passed between different threads.
Notice that a RealmResults is never null not even in the case where it contains no objects. You should always use the OrderedRealmCollectionImpl.size() method to check if a RealmResults is empty or not.
If a RealmResults is built on RealmList through RealmList.where(), it will become empty when the source RealmList gets deleted.
RealmResults can contain more elements than Integer.MAX_VALUE. In that case, you can access only first Integer.MAX_VALUE elements in it.

```
public RealmQuery<E> where()
```
    Returns a RealmQuery, which can be used to query for specific objects from this collection.
    
    Returns:
    
    a RealmQuery object.
    
    See Also:
    
    RealmQuery
  - sort
```
public RealmResults<E> sort(String fieldName1,
                            Sort sortOrder1,
                            String fieldName2,
                            Sort sortOrder2)
```
    Sorts a collection based on the provided fields and sort orders.
    
    Specified by:
    
    sort in interface OrderedRealmCollection<E>
    
    Parameters:
    
    fieldName1 - first field name. Only fields of type boolean, short, int, long, float, double, Date, and String are supported.
    
    sortOrder1 - sort order for first field.
    
    fieldName2 - second field name. Only fields of type boolean, short, int, long, float, double, Date, and String are supported.
    
    sortOrder2 - sort order for second field.
    
    Returns:
    
    a new sorted RealmResults will be created and returned. The original collection stays unchanged.
  - isLoaded
```
public boolean isLoaded()
```
    Returns false if the results are not yet loaded, true if they are loaded.
    
    Returns:
    
    true if the query has completed and the data is available, false if the query is still running in the background.
  - load
```
public boolean load()
```
    Makes an asynchronous query blocking. This will also trigger any registered RealmChangeListener when the query completes.
    
    Returns:
    
    true if it successfully completed the query, false otherwise.
  - addChangeListener
```
public void addChangeListener(RealmChangeListener<RealmResults<E>> listener)
```
    Adds a change listener to this RealmResults.
    Registering a change listener will not prevent the underlying RealmResults from being garbage collected. If the RealmResults is garbage collected, the change listener will stop being triggered. To avoid this, keep a strong reference for as long as appropriate e.g. in a class variable.
```
 
 public class MyActivity extends Activity {

     private RealmResults<Person> results; // Strong reference to keep listeners alive

     \@Override
     protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       results = realm.where(Person.class).findAllAsync();
       results.addChangeListener(new RealmChangeListener<RealmResults<Person>>() {
           \@Override
           public void onChange(RealmResults<Person> persons) {
               // React to change
           }
       });
     }
 }
 
 
```
    Parameters:
    
    listener - the change listener to be notified.
    
    Throws:
    
    IllegalArgumentException - if the change listener is null.
    
    IllegalStateException - if you try to add a listener from a non-Looper or IntentService thread.
  - addChangeListener
```
public void addChangeListener(OrderedRealmCollectionChangeListener<RealmResults<E>> listener)
```
    Adds a change listener to this RealmResults.
    Registering a change listener will not prevent the underlying RealmResults from being garbage collected. If the RealmResults is garbage collected, the change listener will stop being triggered. To avoid this, keep a strong reference for as long as appropriate e.g. in a class variable.
```
 
 public class MyActivity extends Activity {

     private RealmResults<Person> results; // Strong reference to keep listeners alive

     \@Override
     protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       results = realm.where(Person.class).findAllAsync();
       results.addChangeListener(new OrderedRealmCollectionChangeListener<RealmResults<Person>>() {
           \@Override
           public void onChange(RealmResults<Person> persons, OrderedCollectionChangeSet changeSet) {
               // React to change
           }
       });
     }
 }
 
 
```
    Parameters:
    
    listener - the change listener to be notified.
    
    Throws:

  - removeAllChangeListeners
```
public void removeAllChangeListeners()
```

public void removeChangeListener(RealmChangeListener<RealmResults<E>> listener)
```

    Parameters:
    
    listener - the change listener to be removed.
    
    Throws:
    
    IllegalArgumentException - if the change listener is null.

    See Also:
    
    RealmChangeListener

  - asFlowable
```
public <any> asFlowable()
```
    Returns an Rx Flowable that monitors changes to this RealmResults. It will emit the current RealmResults when subscribed to. RealmResults will continually be emitted as the RealmResults are updated - onComplete will never be called.
    If you would like the asFlowable() to stop emitting items you can instruct RxJava to only emit only the first item by using the first() operator:
```
 
 realm.where(Foo.class).findAllAsync().asFlowable()
      .filter(results -> results.isLoaded())
      .first()
      .subscribe( ... ) // You only get the results once
 
 
```
    Note that when the Realm is accessed from threads other than where it was created, IllegalStateException will be thrown. Care should be taken when using different schedulers with subscribeOn() and observeOn(). Consider using Realm.where().find*Async() instead.
    Returns:
    
    RxJava Observable that only calls onNext. It will never call onComplete or OnError.
    
    Throws:
    
    UnsupportedOperationException - if the required RxJava framework is not on the classpath or the corresponding Realm instance doesn't support RxJava.
    
    See Also:
    
    RxJava and Realm
  - asChangesetObservable
```
public <any> asChangesetObservable()
```
    Returns an Rx Observable that monitors changes to this RealmResults. It will emit the current RealmResults when subscribed. For each update to the RealmResult a pair consisting of the RealmResults and the OrderedCollectionChangeSet will be sent. The changeset will be null the first time an RealmResults is emitted.
    RealmResults will continually be emitted as the RealmResults are updated - onComplete will never be called.
    Note that when the Realm is accessed from threads other than where it was created, IllegalStateException will be thrown. Care should be taken when using different schedulers with subscribeOn() and observeOn(). Consider using Realm.where().find*Async() instead.
    
    Returns:
    
    RxJava Observable that only calls onNext. It will never call onComplete or OnError.
    
    Throws:
    
    UnsupportedOperationException - if the required RxJava framework is not on the classpath or the corresponding Realm instance doesn't support RxJava.
