Метод	Описание
Create ( string name, VfsNodeType type, object settings ) : IVfsNode	Creates a new file system entry of the given name and type. In theory every file system should support any VfsNodeType. Standard objects, such as directories and files are obvious. For other objects however, the file system is encouraged to store the passed settings in a specially marked file and treat these files as the appropriate node type. Instances of these objects can be retrieved using VfsObjectFactory.Create(settings). Access rights do not need to be checked by the node implementation. They have been already been checked by the VirtualFileSystem itself.
Delete ( IVfsNode child, DirectoryEntry dentry ) : void	Called to delete a child from a directory. This function deletes a child IVfsNode from a directory. If child is a directory, it will be empty before this call is executed. It is recommended to include a debug sanity check though. If the file system needs to know the name of the child to delete, it can retrieve it from DirectoryEntry.Name.
Lookup ( string name ) : IVfsNode	Requests the IVfsNode to perform a lookup on its children.
Open ( FileAccess access, FileShare sharing ) : object	Opens the specified access.
VfsFile ( IFileSystem fs, uint fileCluster, uint directorySector, uint directoryIndex ) : System.IO	Initializes a new instance of the VfsFile class.

Create() публичный Метод

Creates a new file system entry of the given name and type.

In theory every file system should support any VfsNodeType. Standard objects, such as directories and files are obvious. For other objects however, the file system is encouraged to store the passed settings in a specially marked file and treat these files as the appropriate node type. Instances of these objects can be retrieved using VfsObjectFactory.Create(settings). Access rights do not need to be checked by the node implementation. They have been already been checked by the VirtualFileSystem itself.

The specified node type is not supported in the file system owning the node. See remarks about this.

public Create ( string name, VfsNodeType type, object settings ) : IVfsNode
name	string	The name of the file system entry to create.
type	VfsNodeType	The type of the file system entry. See remarks.
settings	object	Potential settings for the file systeme entry.
Результат	IVfsNode

Delete() публичный Метод

Called to delete a child from a directory.

This function deletes a child IVfsNode from a directory. If child is a directory, it will be empty before this call is executed. It is recommended to include a debug sanity check though. If the file system needs to know the name of the child to delete, it can retrieve it from DirectoryEntry.Name.

The object does not support removal this way. There's most likely an object specific API to remove this IVfsNode.

public Delete ( IVfsNode child, DirectoryEntry dentry ) : void
child	IVfsNode	The IVfsNode interface of the child.
dentry	Mosa.FileSystem.VFS.DirectoryEntry	The DirectoryEntry of the child.
Результат	void

Lookup() публичный Метод

Requests the IVfsNode to perform a lookup on its children.

public Lookup ( string name ) : IVfsNode
name	string	The name of the item to find.
Результат	IVfsNode

Open() публичный Метод

Opens the specified access.

public Open ( FileAccess access, FileShare sharing ) : object
access	FileAccess	The access.
sharing	FileShare	The sharing.
Результат	object

VfsFile() публичный Метод

Initializes a new instance of the VfsFile class.

public VfsFile ( IFileSystem fs, uint fileCluster, uint directorySector, uint directoryIndex ) : System.IO
fs	IFileSystem	The fs.
fileCluster	uint	The file cluster.
directorySector	uint	The directory sector.
directoryIndex	uint	Index of the directory.
Результат	System.IO
