RealmList (Realm 3.1.1)

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

Type Parameters:

E - the class of objects in list.

All Implemented Interfaces:

OrderedRealmCollection<E>, RealmCollection<E>, Iterable<E>, Collection<E>, List<E>
```
public class RealmList<E extends RealmModel>
extends AbstractList<E>
implements OrderedRealmCollection<E>
```
RealmList is used to model one-to-many relationships in a RealmObject. RealmList has two modes: A managed and unmanaged mode. In managed mode all objects are persisted inside a Realm, in unmanaged mode it works as a normal ArrayList.
Only Realm can create managed RealmLists. Managed RealmLists will automatically update the content whenever the underlying Realm is updated, and can only be accessed using the getter of a RealmObject.
Unmanaged RealmLists can be created by the user and can contain both managed and unmanaged RealmObjects. This is useful when dealing with JSON deserializers like GSON or other frameworks that inject values into a class. Unmanaged elements in this list can be added to a Realm using the Realm.copyToRealm(Iterable) method.
RealmList can contain more elements than Integer.MAX_VALUE. In that case, you can access only first Integer.MAX_VALUE elements in it.

public RealmList()
```
    Creates a RealmList in unmanaged mode, where the elements are not controlled by a Realm. This effectively makes the RealmList function as a ArrayList and it is not possible to query the objects in this state.
    Use Realm.copyToRealm(Iterable) to properly persist its elements in Realm.
  - RealmList
```
public RealmList(E... objects)
```
    Creates a RealmList in unmanaged mode with an initial list of elements. A RealmList in unmanaged mode function as a ArrayList and it is not possible to query the objects in this state.
    Use Realm.copyToRealm(Iterable) to properly persist all unmanaged elements in Realm.
    
    Parameters:
    
    objects - initial objects in the list.
- Method Detail
  - isValid
```
public boolean isValid()
```
    Checks if the collection is still valid to use, i.e., the Realm instance hasn't been closed. It will always return true for an unmanaged collection.
    
    Specified by:
    
    isValid in interface RealmCollection<E extends RealmModel>
    
    Returns:
    
    true if it is still valid to use or an unmanaged collection, false otherwise.
  - isManaged
```
public boolean isManaged()
```
    Checks if the collection is managed by Realm. A managed collection is just a wrapper around the data in the underlying Realm file. On Looper threads, a managed collection will be live-updated so it always points to the latest data. Managed collections are thread confined so that they cannot be accessed from other threads than the one that created them.
    
    If this method returns false, the collection is unmanaged. An unmanaged collection is just a normal java collection, so it will not be live updated.
    
    Specified by:
    
    isManaged in interface RealmCollection<E extends RealmModel>
    
    Returns:
    
    true if this is a managed RealmCollection, false otherwise.
  - add
```
public void add(int location,
                E object)
```
    Inserts the specified object into this List at the specified location. The object is inserted before any previous element at the specified location. If the location is equal to the size of this List, the object is added at the end.
    1. Unmanaged RealmLists: It is possible to add both managed and unmanaged objects. If adding managed objects to an unmanaged RealmList they will not be copied to the Realm again if using Realm.copyToRealm(RealmModel) afterwards.
    2. Managed RealmLists: It is possible to add unmanaged objects to a RealmList that is already managed. In that case the object will transparently be copied to Realm using Realm.copyToRealm(RealmModel) or Realm.copyToRealmOrUpdate(RealmModel) if it has a primary key.
    Specified by:
    
    add in interface List<E extends RealmModel>
    
    Overrides:
    
    add in class AbstractList<E extends RealmModel>
    
    Parameters:
    
    location - the index at which to insert.
    
    object - the object to add.
    
    Throws:
    
    IllegalStateException - if Realm instance has been closed or container object has been removed.
    
    IndexOutOfBoundsException - if location < 0 || location > size().
  - add
```
public boolean add(E object)
```
    Adds the specified object at the end of this List.
    1. Unmanaged RealmLists: It is possible to add both managed and unmanaged objects. If adding managed objects to an unmanaged RealmList they will not be copied to the Realm again if using Realm.copyToRealm(RealmModel) afterwards.
    2. Managed RealmLists: It is possible to add unmanaged objects to a RealmList that is already managed. In that case the object will transparently be copied to Realm using Realm.copyToRealm(RealmModel) or Realm.copyToRealmOrUpdate(RealmModel) if it has a primary key.

             E object)
```
    Replaces the element at the specified location in this list with the specified object.
    1. Unmanaged RealmLists: It is possible to add both managed and unmanaged objects. If adding managed objects to an unmanaged RealmList they will not be copied to the Realm again if using Realm.copyToRealm(RealmModel) afterwards.
    2. Managed RealmLists: It is possible to add unmanaged objects to a RealmList that is already managed. In that case the object will transparently be copied to Realm using Realm.copyToRealm(RealmModel) or Realm.copyToRealmOrUpdate(RealmModel) if it has a primary key.

  - move
```
public void move(int oldPos,
                 int newPos)

    Parameters:
    
    oldPos - index of RealmObject to move.
    
    newPos - target position. If newPos < oldPos the object at the location will be shifted to the right. If oldPos < newPos, indexes > oldPos will be shifted once to the left.
    
    Throws:
    
    IllegalStateException - if Realm instance has been closed or parent object has been removed.
    
    IndexOutOfBoundsException - if any position is outside [0, size()].

    Returns:
    
    the removed object.
    
    Throws:
    
    IllegalStateException - if Realm instance has been closed or parent object has been removed.
    
    IndexOutOfBoundsException - if location < 0 || location >= size().
  - remove
```
public boolean remove(Object object)
```
    Removes one instance of the specified object from this Collection if one is contained. This implementation iterates over this Collection and tests each element e returned by the iterator, whether e is equal to the given object. If object != null then this test is performed using object.equals(e), otherwise using object == null. If an element equal to the given object is found, then the remove method is called on the iterator and true is returned, false otherwise. If the iterator does not support removing elements, an UnsupportedOperationException is thrown.
    
    Specified by:
    
    remove in interface Collection<E extends RealmModel>
    
    Specified by:
    
    remove in interface List<E extends RealmModel>

    Parameters:
    
    object - the object to remove.
    
    Returns:
    
    true if this Collection is modified, false otherwise.
    
    Throws:
    
    ClassCastException - if the object passed is not of the correct type.
    
    NullPointerException - if object is null.
  - removeAll
```
public boolean removeAll(Collection<?> collection)
```
    Removes all occurrences in this Collection of each object in the specified Collection. After this method returns none of the elements in the passed Collection can be found in this Collection anymore.
    This implementation iterates over the Collection and tests each element e returned by the iterator, whether it is contained in the specified Collection. If this test is positive, then the remove method is called on the iterator.

    if no objects exist or they all have null as the value for the given date field, null will be returned. Otherwise the minimum date is returned. When determining the minimum date, objects with null values are ignored.
  - deleteAllFromRealm
```
public boolean deleteAllFromRealm()
```
    This deletes all objects in the collection from the underlying Realm as well as from the collection.
    
    Specified by:
    
    deleteAllFromRealm in interface RealmCollection<E extends RealmModel>
    
    Returns:
    
    true if objects was deleted, false otherwise.
  - isLoaded
```
public boolean isLoaded()
```
    Checks if a collection has finished loading its data yet.
    
    Specified by:
    
    isLoaded in interface RealmCollection<E extends RealmModel>
    
    Returns:
    
    true if data has been loaded and is available, false if data is still being loaded.
  - load
```
public boolean load()
```
    Blocks the collection until all data are available.
    
    Specified by:
    
    load in interface RealmCollection<E extends RealmModel>
    
    Returns:
    
    true if the data could be successfully loaded, false otherwise.
  - contains
```
public boolean contains(Object object)
```
    Returns true if the list contains the specified element when attached to a Realm. This method will query the native Realm underlying storage engine to quickly find the specified element.
    If the list is not attached to a Realm, the default List.contains(Object) implementation will occur.
    
    Specified by:
    
    contains in interface RealmCollection<E extends RealmModel>
    
    Specified by:
    
    contains in interface Collection<E extends RealmModel>
    
    Specified by:
    
    contains in interface List<E extends RealmModel>
    
    Overrides:
    
    contains in class AbstractCollection<E extends RealmModel>
    
    Parameters:
    
    object - the element whose presence in this list is to be tested.
    
    Returns:
    
    true if this list contains the specified element otherwise false.
  - iterator
```
public Iterator<E> iterator()
```
    Specified by:
    
    iterator in interface Iterable<E extends RealmModel>
    
    Specified by:
    
    iterator in interface Collection<E extends RealmModel>
    
    Specified by:
    
    iterator in interface List<E extends RealmModel>
    
    Overrides:
    
    iterator in class AbstractList<E extends RealmModel>
  - listIterator
```
public ListIterator<E> listIterator()
```
    Specified by:
    
    listIterator in interface List<E extends RealmModel>
    
    Overrides:
    
    listIterator in class AbstractList<E extends RealmModel>
  - listIterator
```
public ListIterator<E> listIterator(int location)
```
    Specified by:
    
    listIterator in interface List<E extends RealmModel>
    
    Overrides:
    
    listIterator in class AbstractList<E extends RealmModel>
  - createSnapshot
```
public OrderedRealmCollectionSnapshot<E> createSnapshot()
```
    Creates a snapshot from this OrderedRealmCollection.
    
    Specified by:
    
    createSnapshot in interface OrderedRealmCollection<E extends RealmModel>
    
    Returns:
    
    the snapshot of this collection.

    OrderedRealmCollectionSnapshot
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class AbstractCollection<E extends RealmModel>
  - asObservable
```
public <any> asObservable()
```
    Returns an Rx Observable that monitors changes to this RealmList. It will emit the current RealmList when subscribed to. RealmList will continually be emitted as the RealmList is updated - onComplete will never be called.
    If you would like the asObservable() to stop emitting items you can instruct RxJava to only emit only the first item by using the first() operator:
```
 
 list.asObservable()
      .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().
    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.

    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.
  - removeChangeListener
```
public void removeChangeListener(OrderedRealmCollectionChangeListener<RealmList<E>> listener)
```
    Removes the specified change listener.
    
    Parameters:
