A publisher that emits Void each time the object changes.
Despite the name, this actually emits after the object has changed.
Creates an unmanaged instance of a Realm object.
The value argument is used to populate the object. It can be a key-value coding compliant object, an array or dictionary returned from the methods in NSJSONSerialization, or an Array containing one element for each managed property. An exception will be thrown if any required properties are not present and those properties were not defined with default values.
When passing in an Array as the value argument, all properties must be present, valid and in the same order as the properties defined in the model.
Call add(_:) on a Realm instance to add an unmanaged object into that Realm.
Swift
public convenience init(value: Any) value
The value used to populate the object.
The Realm which manages the object, or nil if the object is unmanaged.
Swift
public var realm: Realm? { get }The object schema which lists the managed properties for the object.
Indicates if the object can no longer be accessed because it is now invalid.
An object can no longer be accessed if the object has been deleted from the Realm that manages it, or if invalidate() is called on that Realm. This property is key-value observable.
Swift
@objc
dynamic open override var isInvalidated: Bool { get }A human-readable description of the object.
DeclarationSwift
open override var description: String { get }Override this method to specify the name of a property to be used as the primary key.
Only properties of types String and Int can be designated as the primary key. Primary key properties enforce uniqueness for each value whenever the property is set, which incurs minor overhead. Indexes are created automatically for primary key properties.
Swift
@objc
open class func primaryKey() -> String?The name of the property designated as the primary key, or nil if the model has no primary key.
Override this method to specify the names of properties to ignore. These properties will not be managed by the Realm that manages the object.
DeclarationSwift
@objc
open class func ignoredProperties() -> [String]An array of property names to ignore.
Returns an array of property names for properties which should be indexed.
Only string, integer, boolean, Date, and NSDate properties are supported.
Swift
@objc
open class func indexedProperties() -> [String]An array of property names.
Key-Value Coding & Subscripting
Returns or sets the value of the property with the given name.
DeclarationSwift
@objc
open subscript(key: String) -> Any? { get set }Registers a block to be called each time the object changes.
The block will be asynchronously called after each write transaction which deletes the object or modifies any of the managed properties of the object, including self-assignments that set a property to its existing value.
For write transactions performed on different threads or in different processes, the block will be called when the managing Realm is (auto)refreshed to a version including the changes, while for local write transactions it will be called at some point in the future after the write transaction is committed.
If no queue is given, notifications are delivered via the standard run loop, and so can’t be delivered while the run loop is blocked by other activity. If a queue is given, notifications are delivered to that queue instead. When notifications can’t be delivered instantly, multiple notifications may be coalesced into a single notification.
Unlike with List and Results, there is no “initial” callback made after you add a new notification block.
Only objects which are managed by a Realm can be observed in this way. You must retain the returned token for as long as you want updates to be sent to the block. To stop receiving updates, call invalidate() on the token.
It is safe to capture a strong reference to the observed object within the callback block. There is no retain cycle due to that the callback is retained by the returned token and not by the object itself.
Warning
Parameters queue
The serial dispatch queue to receive notification on. If nil, notifications are delivered to the current thread.
block
The block to call with information about changes to the object.
Return ValueA token which must be held for as long as you want updates to be delivered.
Returns whether two Realm objects are the same.
Objects are considered the same if and only if they are both managed by the same Realm and point to the same underlying object in the database.
Note
Equality comparison is implemented by isEqual(_:). If the object type is defined with a primary key, isEqual(_:) behaves identically to this method. If the object type is not defined with a primary key, isEqual(_:) uses the NSObject behavior of comparing object identity. This method can be used to compare two objects for database equality whether or not their object type defines a primary key.
Swift
public func isSameObject(as object: Object?) -> Bool object
The object to compare the receiver to.
Indicates if this object is frozen.
DeclarationSwift
public var isFrozen: Bool { get }Returns a frozen (immutable) snapshot of this object.
The frozen copy is an immutable object which contains the same data as this object currently contains, but will not update when writes are made to the containing Realm. Unlike live objects, frozen objects can be accessed from any thread.
Warning
DeclarationSwift
public func freeze() -> SelfReturns a live (mutable) reference of this object.
This method creates a managed accessor to a live copy of the same frozen object. Will return self if called on an already live object.
DeclarationSwift
