isActive

public boolean isActive()

Description copied from interface: StorageActivePart

Queries whether the part is actually active right now. This might return true even despite some "running" flag being set to false because there might be one last loop cycle execution before checking the "running" flag again.

Specified by:

Returns:

if the part is actually active right now.
