FilenameC

Methods:

DirectoryC(): Default constructor.
Default value is current directory.
DirectoryC(const StringC & name): Construct from a string.
DirectoryC(const DirectoryC & name): Copy constructor.
BooleanT Create(const FilePermissionC & Acc = FilePermissionC()) const: Create a directory by this name.
BooleanT IsValid() const: Is this really a directory ?
DListC<FilenameC> List() const: List contents of directory.
Will return an empty list if anything goes wrong. Gives names of contents relative to this directory , without any leading or trailing "/"
DListC<FilenameC> List(const StringC & pre,const StringC & post) const: List contents of directory, returning only files with the given prefix and postfix.
Either (or both) pre and post maybe empty strings.. Will return an empty list if anything goes wrong.
DListC<FilenameC> FiltList(const StringC & filter) const: List contents of directory, returning only files matching the given filter.
BooleanT Copy(const FilenameC & othDir,BooleanT rec = TRUE,BooleanT lazy = FALSE,BooleanT sync = FALSE,BooleanT verb = FALSE): Copy all files in this directory into 'othDir'.
This will make 'othDir' if necessary. When 'rec' is true it will do so recursively, if false subdirectories will be ignored. If othDir is an empty string the currect directory is used.
if lazy is true, files are only updated if they have a later date than the target.
if sync is true, all files that are not in the source directory are removed.

BooleanT MakeDir(const FilePermissionC & Acc = FilePermissionC()) const: Make a directory with this name.
Return: TRUE = Directory created ok.
BooleanT Exists() const: Test if the file/directory given in this path exists.
Return: TRUE = File does exist.
BooleanT Rename(const StringC & newname) const: Rename file.
This does NOT change the value of this filename. Ret TRUE=Succeeded.
BooleanT IsReadable() const: Test if the file/directory is readable by this process.
Return: TRUE = It can be read.

If removeAMD is TRUE, any automount prefix will also be remove from the path.
void SetAMDPrefix(StringC prefix): Set the AMD prefix.
BooleanT HasExtension(StringC ext,BooleanT caseSens = FALSE) const: Test if filename has the given extention.
caseSens = FALSE means case is ignored.

That is the text after the last '.' in the name component. Returns empty string if none found.

Returns this filename if is not found on path.
FilenameC Search(const DListC<StringC> & pathList) const: Search through a list of paths for this file.
Returns this filename if is not found on path. Usefull for searching through the 'PATH' enviroment variable.
