◆ attribute()

void SysFs::attribute	(	SysFsDirectory *	parent,

◆ createDirectory()

bool SysFs::createDirectory	(	File *	parent,
		const String &	filename,
		uint32_t	mask
	)

inlineoverrideprotectedvirtual

createDirectory calls this after it has parsed the string path.

Implements Filesystem.

Definition at line 44 of file SysFs.h.

◆ createFile()

bool SysFs::createFile	(	File *	parent,
		const String &	filename,
		uint32_t	mask
	)

inlineoverrideprotectedvirtual

createFile calls this after it has parsed the string path.

Implements Filesystem.

Definition at line 41 of file SysFs.h.

◆ createSymlink()

bool SysFs::createSymlink	(	File *	parent,
		const String &	filename,
		const String &	value
	)

inlineoverrideprotectedvirtual

createSymlink calls this after it has parsed the string path.

Implements Filesystem.

Definition at line 47 of file SysFs.h.

◆ directory()

SysFsDirectory * SysFs::directory	(	SysFsDirectory *	parent,
		const char *	name
	)

private

Definition at line 98 of file SysFs.cc.

◆ getRoot()

File * SysFs::getRoot ( ) const

inlineoverridevirtual

Returns the root filesystem node.

Implements Filesystem.

Definition at line 28 of file SysFs.h.

◆ getVolumeLabel()

const String & SysFs::getVolumeLabel ( ) const

overridevirtual

Returns a string identifying the volume label.

Implements Filesystem.

Definition at line 93 of file SysFs.cc.

◆ initialise()

bool SysFs::initialise ( Disk * pDisk )

overridevirtual

Populates this filesystem with data from the given Disk device.

Returns: true on success, false on failure.

Implements Filesystem.

Definition at line 212 of file SysFs.cc.

References VFS::instance(), and VFS::trackFile().

◆ removeNode()

bool SysFs::removeNode	(	File *	parent,
		const String &	filename,
		File *	file
	)

inlineoverrideprotectedvirtual

Remove a backing node while the VFS holds the parent's namespace lock. A successful implementation must retire the parent's cached entry before returning and must recheck directory emptiness while holding the child's namespace lock.

Implements Filesystem.

Definition at line 50 of file SysFs.h.

◆ symlink()

void SysFs::symlink	(	SysFsDirectory *	parent,
		const char *	name,
		const String &	target
	)

private

Definition at line 112 of file SysFs.cc.

◆ sync()

SyncStatus SysFs::sync ( )

inlineoverridevirtual

Completes data, metadata and device writeback for changes made before entry.

Reimplemented from Filesystem.

Definition at line 32 of file SysFs.h.
