Class DriveOperationsSequence

java.lang.Object

net.lecousin.framework.concurrent.Task<Void,IOException>

net.lecousin.framework.concurrent.tasks.drives.DriveOperationsSequence

public class DriveOperationsSequence
extends Task<Void,IOException>

Task to execute a sequence of operation on a file, and avoid separate them into different tasks. The task may be started before all operations are specified if autoStart is set to true. If autoStart is true, the method endOfOperations must be called to indicate that no more operation will be added. If the method endOfOperations is not yet called and there is no more operation to execute, the task will block until a new operation is added or the method endOfOperations is called.
