Description copied from interface: FileSystemChangeFinder

Gets the changes in the repository against which the given session is bound for the given synchronization root paths, since the given last successful synchronization date and without exceeding the given limit. The change summaries are mapped back to the file system view: the file system items might not always have the same tree layout as the backing documents in the repositories but this is a back-end detail that the client does not have to deal with.

Specified by:

getFileSystemChanges in interface FileSystemChangeFinder

Parameters:

session - the session bound to a specific repository

lastActiveRootRefs - docrefs of the roots as reported by the last successful synchronization (can be empty or null)

activeRoots - the currently active synchronization roots

lastSuccessfulSyncDate - the last successful synchronization date as measured on the server for this user device.

syncDate - the current synchronization date (upper bound on the date of the changes to return). This date is typically obtained by calling getMostRecentChangeDate

limit - the maximum number of changes to fetch

Returns:

the list of document changes

Throws:

TooManyChangesException - if the number of changes found has exceeded the limit

ClientException - if the access to the repository fails for another reason.

getCurrentDate

public long getCurrentDate()

Return the current time to query the logDate field of the audit log. This time intentionally truncated to 0 milliseconds to have a consistent behavior across databases.
