Member Function Documentation

virtual bool DtFilename::absolute ( ) const

virtual

Returns true if the filename is an absolute filename, or a relative filename, respectively.

static DtString DtFilename::absolutePath	(	const DtString &	path,
		DtString &	newAbsolutePath
	)

static

Given a file path to an existing file, make it an absolute path in the provided result.

Result is an empty string if file does not exist. Return a reference to the absolute path

virtual void DtFilename::append ( DtFilename const & filename )

virtual

This filename is considered a path and the supplied filename is appended.

The filename may be an absolute or relative path. If the filename is absolute, then it replaces this one. A separator is inserted between this path and the filename if necessary.

static DtFilename DtFilename::combine	(	const DtFilename &	path,
		const DtFilename &	filename
	)

static

Constructs a new filename by combining the path with filename, which is an absolute or relative path.

If the filename is an absolute filename, then filename is returned. If the filename is a relative filename, then path is prepended to it. If path is empty, then the filename is returned.

virtual bool DtFilename::exists ( ) const

virtual

Returns true if the filename exists.

virtual DtString DtFilename::extension ( ) const

virtual

Returns the file extension, which are all the characters following the last '.

' period. If there is no extension in the filename, an empty string is returned.

virtual unsigned long DtFilename::fileLength ( ) const

virtual

Returns the size of the file in bytes.

If file does not exist results are undefined.

virtual bool DtFilename::isReadable ( ) const

virtual

Return true if the filename is readable.

virtual bool DtFilename::isWritable ( ) const

virtual

Returns true if the filename is writable.

static const DtFilename& DtFilename::nullFilename ( )

static

Return empty filename.

DtFilename& DtFilename::operator= ( const DtFilename & orig )

assignment operator

DtFilename& DtFilename::operator= ( const DtString & orig )

virtual

Reimplemented from DtString.

DtFilename& DtFilename::operator= ( const char * orig )

virtual

Reimplemented from DtString.

virtual void DtFilename::prepend ( DtFilename const & pathName )

virtual

This filename is considered a relative path (or filename) and the supplied path is prepended.

The path name may be an absolute or relative path. If this filename is absolute it is left unchanged. A separator is inserted between the path and this filename if necessary.

virtual bool DtFilename::relative ( ) const

virtual

void DtFilename::replaceSlashes ( )

protected

Replaces slashes.

On unix, this replaces backslashes with forward slashes. Vice versa on win32. Hail Mr Gates. This is not virtual, because we call this from the constructors and destructor.

virtual bool DtFilename::searchAlternatePath ( const char * theAlternatePath )

virtual

Search for this file, first using this filename.

If not found, and the alternate filename isn't NULL, prepend the alternate path and try a second time (note that prepend will not update an absolute path). Returns true if the filename exists and updates this filename to match the found file. Returns false if not found and filename is not changed.

static char DtFilename::separator ( )

static

Returns the separator used in representing directories.

virtual void DtFilename::setExtension ( const DtString & extension )

virtual

Sets the extension for the filename, if the existing file has an extension it is removed, else this extension is appended.

The extension string does NOT need a leading period.

virtual void DtFilename::stripExtension ( )

virtual

Strip the extension from the filename.

This will remove all characters after the last '.' in the filename including the '.'. The implementation: DtFilename path = DtFilename::stripFilename(*this); this->stripPath(); this->snipBack('.'); this->prepend(path);

static DtFilename DtFilename::stripExtension ( const DtFilename & orig )

static

Strip the extension from a filename.

virtual void DtFilename::stripFilename ( )

virtual

Strip the filename from this path.

static DtFilename DtFilename::stripFilename ( const DtFilename & orig )

static

Strip the filename from a path.

virtual void DtFilename::stripPath ( )

virtual

Strip the path from this filename.

static DtFilename DtFilename::stripPath ( const DtFilename & orig )

static

Strip the path from a filename.
