zipios::FilePath - FilePath represents a path to a file or directory name. SYNOPSIS
#include <filepath.h> Public Member Functions FilePath (const string &path='', bool check_exists=false) Constructor. FilePath & operator= (const string &rhs) operator string () const FilePath operator+ (const FilePath &name) const Concatenates FilePath objects. FilePath filename () const Returns filename of the FilePath object by pruning the path off. bool exists () const bool isRegular () const bool isDirectory () const bool isCharSpecial () const bool isBlockSpecial () const bool isSocket () const bool isFifo () const Protected Member Functions void pruneTrailingSeparator () Prunes the trailing separator of a specified path. void check () const This function sets _checked to true, stats the path, to see if it exists and to determine what type of file it is. Protected Attributes bool _checked bool _exists bool _is_reg bool _is_dir bool _is_char bool _is_block bool _is_socket bool _is_fifo string _path Static Protected Attributes static const char _separator = '/' Detailed Description FilePath represents a path to a file or directory name. FilePath has member functions to check if the file path is a valid file system entity, and to check what kind of file system entity it is, e.g. is it a file, a directory, a pipe etc. Definition at line 18 of file filepath.h. Constructor &; Destructor Documentation zipios::FilePath::FilePath (const string &path = '', boolcheck_exists = false) Constructor. Parameters: path A string representation of the path. check_exists If true is specified the constructor will check the existence and type of the path immidiately, instead of deferring that task until it is needed. Definition at line 18 of file filepath.cpp. Member Function Documentation void zipios::FilePath::check () const [protected] This function sets _checked to true, stats the path, to see if it exists and to determine what type of file it is. All the query functions check if _checked is true, and if it isn't they call check(). This means stat'ing is deferred until it becomes necessary. Definition at line 27 of file filepath.cpp. bool zipios::FilePath::exists () const [inline] Returns: true If the path is a valid file system entity. Definition at line 129 of file filepath.h. FilePath zipios::FilePath::filename () const [inline] Returns filename of the FilePath object by pruning the path off. Definition at line 119 of file filepath.h. bool zipios::FilePath::isBlockSpecial () const [inline] Returns: true if the path is block special (a block device file). Definition at line 157 of file filepath.h. bool zipios::FilePath::isCharSpecial () const [inline] Returns: true if the path is character special (a character device file). Definition at line 150 of file filepath.h. bool zipios::FilePath::isDirectory () const [inline] Returns: true if the path is a directory. Definition at line 143 of file filepath.h. bool zipios::FilePath::isFifo () const [inline] Returns: true if the path is a Fifo (a pipe). Definition at line 171 of file filepath.h. bool zipios::FilePath::isRegular () const [inline] Returns: true if the path is a regular file. Definition at line 136 of file filepath.h. bool zipios::FilePath::isSocket () const [inline] Returns: true if the path is a socket. Definition at line 164 of file filepath.h. FilePath zipios::FilePath::operator+ (const FilePath &name) const [inline] Concatenates FilePath objects. A file separator is inserted if appropriate. Definition at line 111 of file filepath.h. void zipios::FilePath::pruneTrailingSeparator () [inline, protected] Prunes the trailing separator of a specified path.
