registerTask

public ProgressObserver.ITask registerTask(java.lang.String task)

Description copied from class: ProgressObserver

Registers a task for notify about processing progress.

Specified by:

registerTask in class ProgressObserver

Parameters:

task - the name of the task

Returns:

the task identification

registerSubtask

public ProgressObserver.ISubtask registerSubtask(java.lang.String subtask)

Description copied from class: ProgressObserver

Registers a subtask to notify about processing progress.

Specified by:

registerSubtask in class ProgressObserver

Parameters:

subtask - the name of the sub task

Returns:

the task identification

notifyStart

public void notifyStart(ProgressObserver.ITask task,
                        ProgressObserver.ISubtask subtask,
                        int max)

Description copied from class: ProgressObserver

Notifies about starting a (sub)task. Subtask notifications shall occur after task notifications, i.e. nested.

Specified by:

notifyStart in class ProgressObserver

Parameters:

task - the identification of task to notify about (initially use ProgressObserver.registerTask(String) for registering a task)

subtask - the subtask (may be ProgressObserver.NO_SUBTASK) (initially use ProgressObserver.registerSubtask(String) for registering a sub task)

max - the intended maximum steps of the subtask

notifyProgress

public void notifyProgress(ProgressObserver.ITask task,
                           ProgressObserver.ISubtask subtask,
                           int step,
                           int max)

Description copied from class: ProgressObserver

Notifies about processing a task or a subtask.

Specified by:

notifyProgress in class ProgressObserver

Parameters:

task - the identification of the task to notify about (initially use ProgressObserver.registerTask(String) for registering a task)

subtask - the identification of the subtask (may be ProgressObserver.NO_SUBTASK, initially use ProgressObserver.registerSubtask(String) for registering a sub task)

step - the current step in 0<=step<=max

max - the maximum number of steps, ignored if negative and value from start notification is used instead

notifyEnd

public void notifyEnd(ProgressObserver.ITask task,
                      ProgressObserver.ISubtask subtask)

Description copied from class: ProgressObserver

Notifies about ending a (sub)task. Subtask notifications shall occur before task notifications, i.e. correctly nested. Use the identifications returned by ProgressObserver.registerTask(String) and ProgressObserver.registerSubtask(String). This method shall implicitly unregister the given task and/or subtask.

Specified by:

notifyEnd in class ProgressObserver

Parameters:

task - the identification of the task which ends (initially use ProgressObserver.registerTask(String) for registering a task)

subtask - the identification of the subtask with task (may be <ProgressObserver.NO_SUBTASK, if given, only the subtask is supposed to end, initially use ProgressObserver.registerSubtask(String) for registering a sub task)
