Properties

CustomLogger

Gets or sets a custom log function that will be invoked by Sync instead of writing to the standard error. This must be set before using any of the sync API.

Declaration
public static Action<string, LogLevel> CustomLogger { get; set; }
Property Value
Type Description
Action<String, LogLevel>

The custom log function.
Remarks

This callback will not be invoked in a thread-safe manner, so it's up to the implementor to ensure that log messages arriving from multiple threads are processed without garbling the final output.

OnProgress

Gets or sets a callback that is invoked when download progress is made when using GetInstanceAsync(RealmConfigurationBase). This will only be invoked for the initial download of the Realm and will not be invoked as futher download progress is made during the lifetime of the Realm. It is ignored when using GetInstance(RealmConfigurationBase).

Declaration
public Action<SyncProgress> OnProgress { get; set; }
Property Value
Type Description
Action<SyncProgress>

TrustedCAPath

Gets or sets the path to the trusted root certificate(s) authority (CA) in PEM format, that should be used to validate the TLS connections to the Realm Object Server.

Declaration
public string TrustedCAPath { get; set; }
Property Value
Type Description
String

The path to the certificate.
Remarks

The file will be copied at runtime into the internal storage.
It is recommended to include only the root CA you trust, and not the entire list of root CA as this file will be loaded at runtime. It is your responsibility to download and verify the correct PEM for the root CA you trust.
This property is ignored on Apple platforms - you should use the KeyChain API to install your certificate instead.

Methods

Initialize(UserPersistenceMode, Byte[], Boolean, String)

Configures various parameters of the sync system, such as the way users are persisted or the base path relative to which files will be saved.

Declaration
public static void Initialize(UserPersistenceMode mode, byte[] encryptionKey = null, bool resetOnError = false, string basePath = null)
Parameters
Type Name Description
UserPersistenceMode mode

The user persistence mode.
Byte[] encryptionKey

The key to encrypt the persistent user store with.
Boolean resetOnError

If set to true reset the persistent user store on error.
String basePath

The base folder relative to which Realm files will be stored.
Remarks

Users are persisted in a realm file within the application's sandbox.

By default User objects are persisted and are additionally protected with an encryption key stored in the iOS Keychain when running on an iOS device (but not on a Simulator). On Android users are persisted in plaintext, because the AndroidKeyStore API is only supported on API level 18 and up. You might want to provide your own encryption key on Android or disable persistence for security reasons.
