removeMetadata

public void removeMetadata(UserIdentity userId,
                           java.util.Collection<java.lang.String> guids)

Description copied from class: ContentStorage

Remove the synchronized content

Specified by:

removeMetadata in class ContentStorage

Parameters:

userId - this user's metadata will be removed from the front-end

guids - optional list of GUIDs, if null, everything is removed

synchronizeAccount

public boolean synchronizeAccount(UserIdentity userId)

Note: the synchronization is only one-way, from Twitter to front-end, no information will be transmitted to the other direction. Also, tags removed from Twitter will NOT be removed from front-end.

Specified by:

synchronizeAccount in class ContentStorage

Parameters:

userId -

Returns:

true on success

synchronizeAccount

public boolean synchronizeAccount(UserIdentity userId,
                                  java.util.Collection<java.lang.String> screenNames)

Note: the synchronization is only one-way, from Twitter to front-end, no information will be transmitted to the other direction. Also, tags removed from Twitter will NOT be removed from front-end. Note that if screenNames are given, the synchronization is targeted ONLY to the given screen names. If screenNames are NOT given, the synchronization is targeted to ALL content. An example use case:

• User synchronized his/her account with screenName name1, which in this case is also the name of the user's own Twitter account
• Then, the user re-syncs with different name, name2. The previously used content is left as it is, because the name name1 is not given.
• Now, re-syncing with the name name1 will ignore all content previously synced with name2, and only synchronize name1. Likewise, using name2 would only sync name2, and ignore all content for name1.
• Re-syncing with both name1 and name2 would retrieve content for both accounts.
• Re-syncing without screenNames will default the retrieval to user's own account name (name1), but synchronize ALL content. In practice this means, that the content for name1 will be synchronized, and all content for name2 will be removed.

Parameters:

userId -

screenNames - use the given collection of screen names instead of the authenticated user's account for synchronization

Returns:

true on success

getServiceType

public CAContentCore.ServiceType getServiceType()

Specified by:

getServiceType in class ContentStorage

Returns:

service type of the storage
