Detailed Description

The StorageInfo class describes the disks mounted on the file system.

This class provides access to the mount information for the Linux filesystem. Each mount point is represented by the FileSystem class. To ensure this class has the most up to date size information, call the update() method. Note that this will automatically be signaled by the operating system when a disk has been mounted or unmounted.
