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
Open ( FileAccess access, FileShare share ) : object	Opens the IVfsNode and returns an object capable of doing something smart with the IVfsNode. This method is central to the entire VFS. It allows for interaction with file system entries in a way not possible with classical operating systems. The result of this function is heavily dependent on the item represented by the node, e.g. for a classic file (stream of bytes) the result of this method call would be a System.IO.Stream. For a device the result would be the driver object, for a directory it would be a System.IO.DirectoryInfo object, for kernel objects the respective object such as System.Threading.EventWaitHandle, System.Threading.Mutex, System.Threading.Thread, System.Diagnostics.Process etc. Note: The object retrieved can be closed by the respective methods on the returned object. There's no close functionality on the IVfsNode itself.
VfsDirectory ( IFileSystem fs, uint directoryCluster ) : System.IO	Initializes a new instance of the VfsDirectory class.

Описание методов

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 system 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

public Lookup ( string name ) : IVfsNode
name	string
Результат	IVfsNode

Open() публичный Метод

Opens the IVfsNode and returns an object capable of doing something smart with the IVfsNode.

This method is central to the entire VFS. It allows for interaction with file system entries in a way not possible with classical operating systems. The result of this function is heavily dependent on the item represented by the node, e.g. for a classic file (stream of bytes) the result of this method call would be a System.IO.Stream. For a device the result would be the driver object, for a directory it would be a System.IO.DirectoryInfo object, for kernel objects the respective object such as System.Threading.EventWaitHandle, System.Threading.Mutex, System.Threading.Thread, System.Diagnostics.Process etc. Note: The object retrieved can be closed by the respective methods on the returned object. There's no close functionality on the IVfsNode itself.

public Open ( FileAccess access, FileShare share ) : object
access	FileAccess
share	FileShare
Результат	object

VfsDirectory() публичный Метод

Initializes a new instance of the VfsDirectory class.

public VfsDirectory ( IFileSystem fs, uint directoryCluster ) : System.IO
fs	IFileSystem	The fs.
directoryCluster	uint	The directory cluster.
Результат	System.IO
