ost::DirTree - A generic class to walk a hierarchical directory structure.
#include <file.h>
DirTree (const char *prefix, unsigned maxdepth)
Construct a directory tree walk starting at the specified prefix.
DirTree (unsigned maxdepth)
Construct an un-opened directory tree of a known maximum depth. virtual
~DirTree ()
void open (const char *prefix)
Open a directory tree path. void close (void)
Close the directory path. char * getPath (void)
Extract the next full pathname from the directory walk. unsigned
perform (const char *prefix)
This is used to step through the filter virtual for an entire subtree, and is
used for cases where a derived DirTree class performs it's primary
operations through filter rather than externally by calling
getPath().
virtual bool filter (const char *file, struct stat *ino)
Virtual method to filter results.
A generic class to walk a hierarchical directory structure.
Author
Directory tree walking.
Construct a directory tree walk starting at the specified prefix. A maximum subdirectory depth is also specified.
Parameters
Construct an un-opened directory tree of a known maximum depth.
Parameters
Close the directory path.
Virtual method to filter results. Virtual override methods should call baseclass method to assure . and .. names are stripped out.
Returns
Parameters
Extract the next full pathname from the directory walk. When returning directories, a '/' is appended. The returned string is a buffer of MAX_PATH size.
Returns
Open a directory tree path.
Parameters
This is used to step through the filter virtual for an entire subtree, and is used for cases where a derived DirTree class performs it's primary operations through filter rather than externally by calling getPath().
