Method Details

getCurrentStatusValue

public int getCurrentStatusValue()

Description copied from interface: BackgroundTaskStatusProvider

Returns the completion status. WARNING: This method must be Thread-Safe!

Specified by:

getCurrentStatusValue in interface BackgroundTaskStatusProvider

Returns:

A number from 0..100 which represents the completion status. If -1 is returned, the progress bar is set to "indeterminate", which means, that the progress bar will float from left to right and reverse. (Useful if status can not be determined) Other values let the progressbar disappear.

getCurrentStatusValueFine

public double getCurrentStatusValueFine()

Description copied from interface: BackgroundTaskStatusProvider

Same as getCurrentStatusValue(), but this method should return a finer granted progress value. If this is not needed, the code for getCurrentStatusValue() could be reused by the client.

Specified by:

getCurrentStatusValueFine in interface BackgroundTaskStatusProvider

Returns:

The current progress value (fine).

getCurrentStatusMessage1

public String getCurrentStatusMessage1()

Description copied from interface: BackgroundTaskStatusProvider

Returns a status message on what is going on. WARNING: This method must be Thread-Safe!

Specified by:

getCurrentStatusMessage1 in interface BackgroundTaskStatusProvider

Returns:

A status message, or null if not needed.

getCurrentStatusMessage2

public String getCurrentStatusMessage2()

Description copied from interface: BackgroundTaskStatusProvider

Returns a status message on what is going on. Is used the same like getCurrentStatusMessage1. This second message adds flexibility. If not needed, the first message should be used and this should return null if not needed. WARNING: This method must be Thread-Safe!

Specified by:

getCurrentStatusMessage2 in interface BackgroundTaskStatusProvider

Returns:

A status message, or null if not needed.

pleaseStop

public void pleaseStop()

public void run()

Specified by:

run in interface Runnable

getNewThreadSafeOptionsWithDefaultSettings

public static ThreadSafeOptions getNewThreadSafeOptionsWithDefaultSettings()

pluginWaitsForUser

public boolean pluginWaitsForUser()

Specified by:

pluginWaitsForUser in interface BackgroundTaskStatusProvider

Returns:

Let this method return true in order to show a "Continue" button in the GUI. When this buttons is clicked, the method pleaseContinueRun is called. Use these two methods to let the user interact with the GUI while the algorithm is waiting for the user to be ready for the continued work of the algorithm.

pleaseContinueRun

public void pleaseContinueRun()

Description copied from interface: BackgroundTaskStatusProvider

This method is called as soon as the user indicates that he is comfortable to let the algorithm continue its work.

Specified by:

setCurrentStatusValue

public void setCurrentStatusValue(int value)

Description copied from interface: BackgroundTaskStatusProvider

Override this method and pass a implementor of this interface to any other service method. This method can use this call to update the status value.
