Detailed Description

The QAbstractFileEngine class provides an abstraction for accessing the filesystem.

The QDir, QFile, and QFileInfo classes all make use of a QAbstractFileEngine internally. If you create your own QAbstractFileEngine subclass (and register it with Qt by creating a QAbstractFileEngineHandler subclass), your file engine will be used when the path is one that your file engine handles.

A QAbstractFileEngine refers to one file or one directory. If the referent is a file, the setFileName(), rename(), and remove() functions are applicable. If the referent is a directory the mkdir(), rmdir(), and entryList() functions are applicable. In all cases the caseSensitive(), isRelativePath(), fileFlags(), ownerId(), owner(), and fileTime() functions are applicable.

A QAbstractFileEngine subclass can be created to do synchronous network I/O based file system operations, local file system operations, or to operate as a resource system to access file based resources.

See also QAbstractFileEngineHandler.

Member Enumeration Documentation

This enum describes the types of extensions that the file engine can support. Before using these extensions, you must verify that the extension is supported (i.e., call supportsExtension()).

This enum was introduced or modified in Qt 4.3.

Enumerator:
AtEndExtension 

Whether the current file position is at the end of the file or not. This extension allows file engines that implement local buffering to report end-of-file status without having to check the size of the file. It is also useful for sequential files, where the size of the file cannot be used to determine whether or not you have reached the end. This extension returns true if the file is at the end; otherwise it returns false. The input and output arguments to extension() are ignored.

FastReadLineExtension 

Whether the file engine provides a fast implementation for readLine() or not. If readLine() remains unimplemented in the file engine, QAbstractFileEngine will provide an implementation based on calling read() repeatedly. If supportsExtension() returns false for this extension, however, QIODevice can provide a faster implementation by making use of its internal buffer. For engines that already provide a fast readLine() implementation, returning false for this extension can avoid unnnecessary double-buffering in QIODevice.

MapExtension 

Whether the file engine provides the ability to map a file to memory.

UnMapExtension 

Whether the file engine provides the ability to unmap memory that was previously mapped.

The permissions and types of a file, suitable for OR'ing together.

See also fileFlags() and setFileName().

Enumerator:
BundleType 

The file is a Mac OS X bundle implies DirectoryType

DirectoryType 

The file is a directory in the file system (i.e. not a link or file).

ExeGroupPerm 

Members of the current user's group have permission to execute the file.

ExeOtherPerm 

All users have permission to execute the file.

ExeOwnerPerm 

The owner of the file has permission to execute it.

ExeUserPerm 

The current user has permission to execute the file.

ExistsFlag 

The file actually exists in the file system.

FileInfoAll 
FileType 

The file is a regular file to the file system (i.e. not a link or directory)

FlagsMask 
HiddenFlag 

The file is hidden.

LinkType 

The file is a link to another file (or link) in the file system (i.e. not a file or directory).

LocalDiskFlag 

The file resides on the local disk and can be passed to standard file functions.

PermsMask 
ReadGroupPerm 

Members of the current user's group have permission to read the file.

ReadOtherPerm 

All users have permission to read the file.

ReadOwnerPerm 

The owner of the file has permission to read it.

ReadUserPerm 

The current user has permission to read the file.

Refresh 

Passing this flag will force the file engine to refresh all flags.

RootFlag 

The file or the file pointed to is the root of the filesystem.

TypesMask 
WriteGroupPerm 

Members of the current user's group have permission to write to the file.

WriteOtherPerm 

All users have permission to write to the file.

WriteOwnerPerm 

The owner of the file has permission to write to it.

WriteUserPerm 

The current user has permission to write to the file.

These values are used to request a file name in a particular format.

See also fileName() and setFileName().

Enumerator:
AbsoluteName 

The absolute path to the file (including the base name).

AbsolutePathName 

The absolute path to the file (excluding the base name).

BaseName 

The name of the file excluding the path.

BundleName 

Returns the name of the bundle implies BundleType is set.

CanonicalName 

Often very similar to LinkName. Will return the true path to the file.

CanonicalPathName 

Same as CanonicalName, excluding the base name.

DefaultName 

The same filename that was passed to the QAbstractFileEngine.

LinkName 

The full file name of the file that this file is a link to. (This will be empty if this file is not a link.)

NFileNames 
PathName 

The path to the file excluding the base name.

See also owner(), ownerId(), and setFileName().

Enumerator:
OwnerGroup 

The group who owns the file.

OwnerUser 

The user who owns the file.

These are used by the fileTime() function.

See also setFileName().

Enumerator:
AccessTime 

When the file was most recently accessed (e.g. read or written to).

CreationTime 

When the file was created.

ModificationTime 

When the file was most recently modified.

Constructor & Destructor Documentation

QtCore.QAbstractFileEngine.QAbstractFileEngine ( System.Type  dummy)
protected
QtCore.QAbstractFileEngine.QAbstractFileEngine ( )
protected

Constructs a new QAbstractFileEngine that does not refer to any file or directory.

See also setFileName().

Member Function Documentation

new bool QtCore.QAbstractFileEngine.AtEnd ( )

Returns true if the current position is at the end of the file; otherwise, returns false.

This function bases its behavior on calling extension() with AtEndExtension. If the engine does not support this extension, false is returned.

This function was introduced in Qt 4.3.

See also extension(), supportsExtension(), and QFile::atEnd().

virtual QAbstractFileEngineIterator QtCore.QAbstractFileEngine.BeginEntryList ( QDir.Filter  filters,
System.Collections.Generic.List< string >  filterNames 
)
virtual

Returns an instance of a QAbstractFileEngineIterator using filters for entry filtering and filterNames for name filtering. This function is called by QDirIterator to initiate directory iteration.

QDirIterator takes ownership of the returned instance, and deletes it when it's done.

See also QDirIterator.

Reimplemented in QtCore.QFSFileEngine.

virtual bool QtCore.QAbstractFileEngine.CaseSensitive ( )
virtual

Should return true if the underlying file system is case-sensitive; otherwise return false.

This virtual function must be reimplemented by all subclasses.

Reimplemented in QtCore.QFSFileEngine.

virtual bool QtCore.QAbstractFileEngine.Close ( )
virtual

Closes the file, returning true if successful; otherwise returns false.

The default implementation always returns false.

Reimplemented in QtCore.QFSFileEngine.

virtual bool QtCore.QAbstractFileEngine.Copy ( string  newName)
virtual

Copies the contents of this file to a file with the name newName. Returns true on success; otherwise, false is returned.

Reimplemented in QtCore.QFSFileEngine.

static QAbstractFileEngine QtCore.QAbstractFileEngine.Create ( string  fileName)
static

Creates and returns a QAbstractFileEngine suitable for processing fileName.

You should not need to call this function; use QFile, QFileInfo or QDir directly instead.

If you reimplemnt this function, it should only return file engines that knows how to handle fileName; otherwise, it should return 0.

See also QAbstractFileEngineHandler.

virtual void QtCore.QAbstractFileEngine.CreateProxy ( )
virtual

Reimplemented in QtCore.QFSFileEngine.

new void QtCore.QAbstractFileEngine.Dispose ( )
virtual QAbstractFileEngineIterator QtCore.QAbstractFileEngine.EndEntryList ( )
virtual

Reimplemented in QtCore.QFSFileEngine.

virtual System.Collections.Generic.List<string> QtCore.QAbstractFileEngine.EntryList ( QDir.Filter  filters,
System.Collections.Generic.List< string >  filterNames 
)
virtual

Requests that a list of all the files matching the filters list based on the filterNames in the file engine's directory are returned.

Should return an empty list if the file engine refers to a file rather than a directory, or if the directory is unreadable or does not exist or if nothing matches the specifications.

This virtual function must be reimplemented by all subclasses.

See also setFileName().

Reimplemented in QtCore.QFSFileEngine.

new QFile.FileError QtCore.QAbstractFileEngine.Error ( )

Returns the QFile::FileError that resulted from the last failed operation. If QFile::UnspecifiedError is returned, QFile will use its own idea of the error status.

See also setError(), QFile::FileError, and errorString().

new string QtCore.QAbstractFileEngine.ErrorString ( )

Returns the human-readable message appropriate to the current error reported by error(). If no suitable string is available, an empty string is returned.

See also error().

new bool QtCore.QAbstractFileEngine.extension ( QAbstractFileEngine.Extension  extension)

This virtual function can be reimplemented in a QAbstractFileEngine subclass to provide support for extensions. The option argument is provided as input to the extension, and this function can store output results in output.

The behavior of this function is determined by extension; see the Extension documentation for details.

You can call supportsExtension() to check if an extension is supported by the file engine.

By default, no extensions are supported, and this function returns false.

This function was introduced in Qt 4.3.

See also supportsExtension() and Extension.

new bool QtCore.QAbstractFileEngine.extension ( QAbstractFileEngine.Extension  extension,
QAbstractFileEngine.ExtensionOption  option = null 
)

This virtual function can be reimplemented in a QAbstractFileEngine subclass to provide support for extensions. The option argument is provided as input to the extension, and this function can store output results in output.

The behavior of this function is determined by extension; see the Extension documentation for details.

You can call supportsExtension() to check if an extension is supported by the file engine.

By default, no extensions are supported, and this function returns false.

This function was introduced in Qt 4.3.

See also supportsExtension() and Extension.

virtual bool QtCore.QAbstractFileEngine.extension ( QAbstractFileEngine.Extension  extension,
QAbstractFileEngine.ExtensionOption  option = null,
QAbstractFileEngine.ExtensionReturn  output = null 
)
virtual

This virtual function can be reimplemented in a QAbstractFileEngine subclass to provide support for extensions. The option argument is provided as input to the extension, and this function can store output results in output.

The behavior of this function is determined by extension; see the Extension documentation for details.

You can call supportsExtension() to check if an extension is supported by the file engine.

By default, no extensions are supported, and this function returns false.

This function was introduced in Qt 4.3.

See also supportsExtension() and Extension.

Reimplemented in QtCore.QFSFileEngine.

virtual QAbstractFileEngine.FileFlag QtCore.QAbstractFileEngine.FileFlags ( QAbstractFileEngine.FileFlag  type = QAbstractFileEngine.FileFlag.FileInfoAll)
virtual

This function should return the set of OR'd flags that are true for the file engine's file, and that are in the type's OR'd members.

In your reimplementation you can use the type argument as an optimization hint and only return the OR'd set of members that are true and that match those in type; in other words you can ignore any members not mentioned in type, thus avoiding some potentially expensive lookups or system calls.

This virtual function must be reimplemented by all subclasses.

See also setFileName().

Reimplemented in QtCore.QFSFileEngine.

new string QtCore.QAbstractFileEngine.fileName ( )

Return the file engine's current file name in the format specified by file.

If you don't handle some FileName possibilities, return the file name set in setFileName() when an unhandled format is requested.

This virtual function must be reimplemented by all subclasses.

See also setFileName() and FileName.

virtual string QtCore.QAbstractFileEngine.fileName ( QAbstractFileEngine.FileName  file = QAbstractFileEngine.FileName.DefaultName)
virtual

Return the file engine's current file name in the format specified by file.

If you don't handle some FileName possibilities, return the file name set in setFileName() when an unhandled format is requested.

This virtual function must be reimplemented by all subclasses.

See also setFileName() and FileName.

Reimplemented in QtCore.QFSFileEngine.

virtual QDateTime QtCore.QAbstractFileEngine.fileTime ( QAbstractFileEngine.FileTime  time)
virtual

If time is CreationTime, return when the file was created. If time is ModificationTime, return when the file was most recently modified. If time is AccessTime, return when the file was most recently accessed (e.g. read or written). If the time cannot be determined return QDateTime() (an invalid date time).

The default implementation always returns false.

Reimplemented in QtCore.QFSFileEngine.

virtual int QtCore.QAbstractFileEngine.Handle ( )
virtual

Returns the native file handle for this file engine. This handle must be used with care; its value and type are platform specific, and using it will most likely lead to non-portable code.

Reimplemented in QtCore.QFSFileEngine.

virtual bool QtCore.QAbstractFileEngine.IsRelativePath ( )
virtual

Return true if the file referred to by this file engine has a relative path; otherwise return false.

This virtual function must be reimplemented by all subclasses.

See also setFileName().

Reimplemented in QtCore.QFSFileEngine.

virtual bool QtCore.QAbstractFileEngine.Link ( string  newName)
virtual

Creates a link from the file currently specified by fileName() to newName. What a link is depends on the underlying filesystem (be it a shortcut on Windows or a symbolic link on Unix). Returns true if successful; otherwise returns false.

Reimplemented in QtCore.QFSFileEngine.

new Pointer<byte> QtCore.QAbstractFileEngine.Map ( long  offset,
long  size,
QFile.MemoryMapFlags  flags 
)

Maps size bytes of the file into memory starting at offset. Returns a pointer to the memory if successful; otherwise returns false if, for example, an error occurs.

This function bases its behavior on calling extension() with MapExtensionOption. If the engine does not support this extension, 0 is returned.

flags is currently not used, but could be used in the future.

This function was introduced in Qt 4.4.

See also unmap() and supportsExtension().

virtual bool QtCore.QAbstractFileEngine.Mkdir ( string  dirName,
bool  createParentDirectories 
)
virtual

Requests that the directory dirName be created. If createParentDirectories is true, then any sub-directories in dirName that don't exist must be created. If createParentDirectories is false then any sub-directories in dirName must already exist for the function to succeed. If the operation succeeds return true; otherwise return false.

This virtual function must be reimplemented by all subclasses.

Reimplemented in QtCore.QFSFileEngine.

virtual bool QtCore.QAbstractFileEngine.Rmdir ( string  dirName,
bool  recurseParentDirectories 
)
virtual

If recurseParentDirectories is false, only the dirName leaf-node should be deleted. In most file systems a directory cannot be deleted using this function if it is non-empty. If the operation succeeds return true; otherwise return false.

This virtual function must be reimplemented by all subclasses.

See also setFileName(), remove(), mkdir(), and isRelativePath().

Reimplemented in QtCore.QFSFileEngine.
