Member Function Documentation

◆ createDirectory()

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

inlineprotectedvirtual

createDirectory calls this after it has parsed the string path.

Implements Filesystem.

Definition at line 307 of file DevFs.h.

◆ createFile()

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

inlineprotectedvirtual

createFile calls this after it has parsed the string path.

Implements Filesystem.

Definition at line 304 of file DevFs.h.

◆ createSymlink()

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

inlineprotectedvirtual

createSymlink calls this after it has parsed the string path.

Implements Filesystem.

Definition at line 310 of file DevFs.h.

◆ getNextInode()

size_t DevFs::getNextInode ( )

virtual

Definition at line 1000 of file DevFs.cc.

◆ getRoot()

virtual File * DevFs::getRoot ( ) const

inlinevirtual

Returns the root filesystem node.

Implements Filesystem.

Definition at line 282 of file DevFs.h.

◆ getTerminalManager()

VirtualTerminalManager & DevFs::getTerminalManager ( )

inline

Definition at line 299 of file DevFs.h.

◆ getVolumeLabel()

virtual const String & DevFs::getVolumeLabel ( ) const

inlinevirtual

Returns a string identifying the volume label.

Implements Filesystem.

Definition at line 285 of file DevFs.h.

◆ handleInput()

void DevFs::handleInput ( InputManager::InputNotification & in )

Definition at line 1008 of file DevFs.cc.

◆ initialise()

bool DevFs::initialise ( Disk * pDisk )

virtual

Populates this filesystem with data from the given Disk device.

Returns: true on success, false on failure.

Implements Filesystem.

Definition at line 814 of file DevFs.cc.

◆ isControllingTerminalSelector()

bool DevFs::isControllingTerminalSelector ( const File * file ) const

inline

Definition at line 293 of file DevFs.h.

◆ removeNode()

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

inlineprotectedvirtual

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 313 of file DevFs.h.

void DevFs::revertInode ( )

virtual

Definition at line 1004 of file DevFs.cc.

◆ sync()

SyncStatus DevFs::sync ( )

inlineoverridevirtual

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

Reimplemented from Filesystem.
