Enum SyncSession.State

java.lang.Object

java.lang.Enum<SyncSession.State>

io.realm.mongodb.sync.SyncSession.State

All Implemented Interfaces:

Serializable, Comparable<SyncSession.State>

Enclosing class:

SyncSession

public static enum SyncSession.State
extends Enum<SyncSession.State>

Enum describing the states a SyncSession can be in. The initial state is INACTIVE.

A Realm will automatically synchronize data with the server if the session is either ACTIVE or DYING and SyncSession.isConnected() returns true.

Enum Constant Summary

Enum Constants

Enum Constant and Description
ACTIVE The Realm is open and data will be synchronized between the device and the server if the underlying connection is ConnectionState.CONNECTED.
DYING The Realm was closed, but still contains data that needs to be synchronized to the server.
INACTIVE This is the initial state.
WAITING_FOR_ACCESS_TOKEN The user is attempting to synchronize data but needs a valid access token to do so.

Method Summary

Modifier and Type	Method and Description
static SyncSession.State	valueOf(String name) Returns the enum constant of this type with the specified name.
static SyncSession.State[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

INACTIVE

public static final SyncSession.State INACTIVE

This is the initial state. The session is closed. No data is being synchronized. The session will automatically transition to ACTIVE when a Realm is opened.

ACTIVE

public static final SyncSession.State ACTIVE

The Realm is open and data will be synchronized between the device and the server if the underlying connection is ConnectionState.CONNECTED.

The session will remain in this state until the Realm is closed. In which case it will become DYING.

DYING

public static final SyncSession.State DYING

The Realm was closed, but still contains data that needs to be synchronized to the server. The session will attempt to upload all local data before going INACTIVE.

WAITING_FOR_ACCESS_TOKEN

public static final SyncSession.State WAITING_FOR_ACCESS_TOKEN

The user is attempting to synchronize data but needs a valid access token to do so. Realm will either use a cached token or automatically try to acquire one based on the current users login. This requires a network connection.

Data cannot be synchronized in this state.

Once a valid token is acquired, the session will transition to ACTIVE.

Method Detail

values

public static SyncSession.State[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (SyncSession.State c : SyncSession.State.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static SyncSession.State valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
