public final classSessionState extends Enum

Overview

Identifies the state of a Session.

Session objects implement a state machine that controls their lifecycle. This enum represents the states of the state machine.

Summary

Constants

SessionState	CREATED Indicates that the Session has not yet been opened and has no cached token.
SessionState	CREATED_TOKEN_LOADED Indicates that the Session has not yet been opened and has a cached token.
SessionState	OPENING Indicates that the Session is in the process of opening.
SessionState	OPENED Indicates that the Session is opened.
SessionState	OPENED_TOKEN_UPDATED Indicates that the Session is opened and that the token has changed.
SessionState	CLOSED_LOGIN_FAILED Indicates that the Session is closed, and that it was not closed normally.
SessionState	CLOSED Indicates that the Session was closed normally.

Methods

static SessionState	values()
static SessionState	valueOf(String name)
boolean	isOpened() Returns a boolean indicating whether the state represents a successfully opened state in which the Session can be used with a Request.
boolean	isClosed() Returns a boolean indicating whether the state represents a closed Session that can no longer be used with a Request.

Constants

public static final SessionState CREATED

Indicates that the Session has not yet been opened and has no cached token. Opening a Session in this state will involve user interaction.

public static final SessionState CREATED_TOKEN_LOADED

Indicates that the Session has not yet been opened and has a cached token. Opening a Session in this state will not involve user interaction.

If you are using Session from an Android Service, you must provide a TokenCachingStrategy implementation that contains a valid token to the Session constructor. The resulting Session will be created in this state, and you can then safely call open, passing null for the Activity.

public static final SessionState OPENING

Indicates that the Session is in the process of opening.

public static final SessionState OPENED

Indicates that the Session is opened. In this state, the Session may be used with a Request.

public static final SessionState OPENED_TOKEN_UPDATED

Indicates that the Session is opened and that the token has changed. In this state, the Session may be used with Request.

Every time the token is updated, StatusCallback is called with this value.

public static final SessionState CLOSED_LOGIN_FAILED

Indicates that the Session is closed, and that it was not closed normally. Typically this means that the open call failed, and the Exception parameter to StatusCallback will be non-null.

public static final SessionState CLOSED

Indicates that the Session was closed normally.

Methods

public static SessionState values()

public static SessionState valueOf(String name)

public boolean isOpened()
