ReadOnlyFileSystemProvider Class

Namespace: Rebex.IO.FileSystem

Assembly: Rebex.FileSystem.dll (version 7.0.9147)

Serves as the base class for read-only file system providers.

When the virtual file system is used in the FileServer component, the server session, which contains information about the user and the active connection, can be accessed using Current property.

Constructors

Name	Description
ReadOnlyFileSystemProvider()	Initializes a new instance of ReadOnlyFileSystemProvider with the Default settings.
ReadOnlyFileSystemProvider(FileSystemProviderSettings)	Initializes a new instance of ReadOnlyFileSystemProvider with the `fileSystemSettings`.

Fields

Name	Description
DefaultDirectoryContentLength	Constant represents default length of the content of a DirectoryNode. The value of the constant is 0.

Properties

Name	Description
OriginalSettings	Gets the original file system settings.
Root	Gets the root directory of this instance.
Settings	Gets the file system settings which were used to create this instance.

Methods

Name	Description
Content(Stream)	Creates a new instance of NodeContent with the underlying `contentStream`. Instances of ReadOnlyFileSystemProvider create new NodeContent using the CreateReadOnlyContent(Stream) method. Instances of ReadWriteFileSystemProvider create new NodeContent using the CreateDelayedWriteContent(Stream) method. When the virtual file system is used in the FileServer component, the server session, which contains information about the user and the active connection, can be accessed using Current property.
CreateChildFileSystem(NodePath)	Creates a child file system with the root path of `directoryPath`.
Dispose()	Performs application-defined tasks associated with freeing, releasing, or resetting resources. Inherited from FileSystemProvider.
Dispose(Boolean)	Releases the resources used by the FileSystemProvider.
Exists(NodePath, NodeType)	Override this method to implement verification of existence of a FileNode or DirectoryNode. When the virtual file system is used in the FileServer component, the server session, which contains information about the user and the active connection, can be accessed using Current property.
GetAttributes(NodeBase)	Returns attributes (NodeAttributes) for the `node`. When the virtual file system is used in the FileServer component, the server session, which contains information about the user and the active connection, can be accessed using Current property.
GetChild(String, DirectoryNode)	Override this method to implement retrieval of DirectoryNode or FileNode with the specified `name` located in the specified `parent` directory. When the virtual file system is used in the FileServer component, the server session, which contains information about the user and the active connection, can be accessed using Current property.
GetChildren(DirectoryNode, NodeType)	Override this method to implement getting a collection of DirectoryNode and/or FileNode objects that are located in the `parent` and value of their property NodeType is contained in the `nodeType`. When the virtual file system is used in the FileServer component, the server session, which contains information about the user and the active connection, can be accessed using Current property.
GetContent(NodeBase, NodeContentParameters)	Override this method to implement retrieval of the content for the `node`. By default, this method is only called for files (instances of the class FileNode). To enable this method for directories (instances of DirectoryNode), add a new instance of FileSystemProviderSettings (with the property EnableGetContentMethodForDirectories set to true) to the ReadOnlyFileSystemProvider(FileSystemProviderSettings) constructor. When the virtual file system is used in the FileServer component, the server session, which contains information about the user and the active connection, can be accessed using Current property.
GetLength(NodeBase)	Override this method to implement retrieval of the length of the content for the `node`. By default, this method is only called for files (instances of the class FileNode). To enable this method for directories (instances of DirectoryNode), add a new instance of FileSystemProviderSettings (with the property EnableGetLengthMethodForDirectories set to true) to the ReadOnlyFileSystemProvider(FileSystemProviderSettings) constructor. When the virtual file system is used in the FileServer component, the server session, which contains information about the user and the active connection, can be accessed using Current property.
GetTimeInfo(NodeBase)	Override this method to implement retrieval of NodeTimeInfo for the `node`. Fill the following NodeTimeInfo properties: CreationTime. AccessTime. LastWriteTime. When the virtual file system is used in the FileServer component, the server session, which contains information about the user and the active connection, can be accessed using Current property.
MakeNewDirectoryNode(String, DirectoryNode)	Factory method that creates a new instance of DirectoryNode with Name initialized to `name` and Parent initialized to `parentNode`. Classes derived from the ReadOnlyFileSystemProvider class or from the class ReadWriteFileSystemProvider can override this method and returns instance of the more specific class derived from DirectoryNode. When the virtual file system is used in the FileServer component, the server session, which contains information about the user and the active connection, can be accessed using Current property.
MakeNewFileNode(String, DirectoryNode)	Factory method that creates a new instance of FileNode that will have Name initialized to `name` and Parent initialized to `parentNode`. Classes derived from the class ReadOnlyFileSystemProvider or from the class ReadWriteFileSystemProvider can override this method and returns instance of the more specific class derived from FileNode. When the virtual file system is used in the FileServer component, the server session, which contains information about the user and the active connection, can be accessed using Current property.
