| console | property |
console:ISpecialFileSet the console for the filesystem. This associates the file "/dev/tty" with the console object. When the applications writes to stdout and stderr, the console object will be called back.
public function get console():ISpecialFile public function set console(value:ISpecialFile):void| DefaultVFS | () | Constructor |
public function DefaultVFS()The default implementation of the IVFS interface
| addBackingStore | () | method |
public function addBackingStore(bs:IBackingStore, prefix:String):voidMounts a backing store as part of the VFS. Once this method returns, files contained within the backing store will be available to the application.
Parameters
bs:IBackingStore — The backing store containing the files to add.
| |
prefix:String — The path to the mount point for this backing store.
This must be an empty directory.
|
| addDirectory | () | method |
public function addDirectory(path:String):voidAdds an empty directory to the filesystem. The directory must not already exist.
Parameters
path:String — The absolute path to the directory to be added.
|
| addFile | () | method |
public function addFile(path:String, data:ByteArray):voidAdds a file to the filesystem. The file must not already exist.
Parameters
path:String — The absolute path to the file to be added.
| |
data:ByteArray — The contents of the file.
|
| addSpecialFile | () | method |
public function addSpecialFile(path:String, specialFile:ISpecialFile):voidAdd a special file to the filesystem. Special files are different from regular files in that they don't have any stored contents. Instead calls to read and write for a special file are routed to a callback object. Special files are never persisted across different runs of the application.
Parameters
path:String — The absolute path to the special file.
| |
specialFile:ISpecialFile — The callback object for the file.
|
| checkPath | () | method |
public function checkPath(path:String):StringChecks a proposed path for a new file.
Parameters
path:String — The absolute path to the file.
|
String — A CheckPathResult describing any problems with the
proposed file name, if any.
|
| closeFile | () | method |
public function closeFile(fileDescriptor:int):voidCloses a file. Once this method returns, the file descriptor is no longer valid.
Parameters
fileDescriptor:int — A file descriptor returned from openFile.
|
| deleteFile | () | method |
public function deleteFile(path:String):voidDeletes a file (or directory) from the filesystem. The file must exist, and if it is a directory, it must be empty.
Parameters
path:String — The absolute path to the file to be deleted.
|
| getDirectoryEntries | () | method |
public function getDirectoryEntries(dirpath:String):Vector.<FileHandle>Retrieves the contents of a directory.
Parameters
dirpath:String — The absolute path to the directory.
|
Vector.<FileHandle> — A Vector of FileHandles, one per file in
the directory, or null if the directory does not
exist.
|
| getFileHandleFromFileDescriptor | () | method |
public function getFileHandleFromFileDescriptor(fileDescriptor:int):FileHandleLooks up the FileHandle instance for a file descriptor.
Parameters
fileDescriptor:int — A file descriptor.
|
FileHandle — The FileHandle corresponding to the file descriptor,
or null if the file descriptor is not valid.
|
| getFileHandleFromPath | () | method |
public function getFileHandleFromPath(path:String):FileHandleResolves a path to a file.
Parameters
path:String — The absolute path to the file.
|
FileHandle — An FileHandle instance for the file, or null if
the file does not exist.
|
| isValidFileDescriptor | () | method |
public function isValidFileDescriptor(fileDescriptor:int):BooleanDetermines whether the argument is a valid file descriptor.
Parameters
fileDescriptor:int — A integer that may or may not be a file descriptor.
|
Boolean — true if the file descriptor is a valid file descriptor
corresponding to an open file, false otherwise.
|
| openFile | () | method |
public function openFile(fileHandle:FileHandle, fileDescriptor:int = -1):intOpens a file and assigns it a file descriptor. A file descriptor is a non-negative integer, which remains valid until closeFile is called.
Parameters
fileHandle:FileHandle — A FileHandle instance for the file to be opened.
| |
fileDescriptor:int (default = -1) |
int — The file descriptor assigned to this file.
