Class ActionFileHandler

java.lang.Object

org.syncany.operations.ActionFileHandler

public class ActionFileHandler
extends java.lang.Object

The action handler manages the ActionRemoteFiles written during an Operation.

In particular, it uploads an initial action file when the operation is started, deletes it when it is finished/terminated, and renews the operation's action file in a given interval.

The renewal is necessary to show other clients that the operation is still running. To ensure action file renewal, the start() method starts a timer that uploads a new ActionRemoteFile every ACTION_RENEWAL_INTERVAL milliseconds. The finish() method stops this timer.
