Detailed Description

Information about the composition of the filesystem.

This object contains global information about our filesystem, including its total size and amount of free space, as well as space usage totals separated out by category.

The default constructor leaves FilesystemInfo uninitialized. Fill it in with up-to-date information by calling gather().

Member Function Documentation

uint32_t Sifteo::FilesystemInfo::allocationUnitSize ( )

inline

Return the size of one allocation unit.

The filesystem allocates space to Volumes in relatively large units. This returns the size of that unit, in bytes.

void Sifteo::FilesystemInfo::gather ( )

inline

Inspects the current state of the filesystem, and fills in the FilesystemInfo accordingly.

This is a relatively heavyweight operation, similar to Volume::list()

uint32_t Sifteo::FilesystemInfo::systemUnits ( )

inline

Space used by system data, in allocation units

System data includes cube pairing information, asset caching data, and other internal storage used to implement basic system functionality. This is the same data which appears as 'system' space in swiss manifest.
