Class DynamicRealmObject

java.lang.Object

io.realm.RealmObject

io.realm.DynamicRealmObject

All Implemented Interfaces:

RealmModel

public final class DynamicRealmObject
extends RealmObject

Class that wraps a normal RealmObject in order to allow dynamic access instead of a typed interface. Using a DynamicRealmObject is slower than using the regular RealmObject class.

hashCode

public int hashCode()

Returns a hash code value for the DynamicRealmObject object.

By the general contract of Object.hashCode(), any two objects for which equals(java.lang.Object) returns true must return the same hash code value.

Note that a RealmObject is a live object, and it might be updated by changes from other threads. This means that a hash code value of the object is not stable, and the value should be neither used as a key in HashMap nor saved in HashSet.

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code value for the object.
