Class DiskUsage

java.lang.Object
org.applecommander.usage.DiskUsage
All Implemented Interfaces:
EventListener, ChangeListener<FileStore.FileStoreChangeEvent>, InformationProvider
Direct Known Subclasses:
BlockUsage, SectorUsage
public abstract class DiskUsage extends Object implements InformationProvider, ChangeListener<FileStore.FileStoreChangeEvent>
Provides a generic DiskUsage interface. Note that the assumption of free and used applies only to disks. Each disk image will supply a more specific usage subclass. Additionally, the assumption is that supplying a used and free count is sufficient. That is, total is the addition of the two and the byte related numbers are just multiplied by the unit size. Finally, used and free are supplied as functions to allow the disk usage to be a long-term construct.
