TokenCachingStrategy

A base class for implementations of a Session token cache.

The Session constructor optionally takes a TokenCachingStrategy, from which it will attempt to load a cached token during construction. Also, whenever the Session updates its token, it will also save the token and associated state to the TokenCachingStrategy.

This is the only mechanism supported for an Android service to use Session. The service can create a custom TokenCachingStrategy that returns the Session provided by an Activity through which the user logged in to Facebook.

インスタンスメソッド
load()

Called during Session construction to get the token state. Typically this is loaded from a persistent store that was previously initialized via save. The caller may choose to keep a reference to the returned Bundle indefinitely. Therefore the TokenCachingStrategy should not store the returned Bundle and should return a new Bundle on every call to this method.

public abstract Bundle load()
Returns
A Bundle that represents the token state that was loaded.
save(Bundle)

Called when a Session updates its token. This is passed a Bundle of values that should be stored durably for the purpose of being returned from a later call to load. Some implementations may choose to store bundle beyond the scope of this call, so the caller should keep no references to the bundle to ensure that it is not modified later.

public abstract void save(Bundle bundle)
パラメーター説明
bundleA Bundle that represents the token state to be saved.
clear()

Called when a Session learns its token is no longer valid or during a call to closeAndClearTokenInformation.closeAndClearTokenInformation to clear the durable state associated with the token.

public abstract void clear()
