Detailed Description

Simple path class. Allows simple conversion to/from path strings with arbitrary directory separators, providing a common representation.

Internally, this is just a simple wrapper around a String, using "/" as a directory separator. It escapes it using "|" if / is used inside a path component.

Constructor & Destructor Documentation

Path() [1/4]

Common::Path::Path ( )

inline

Construct a new empty path.

Path() [2/4]

Common::Path::Path ( const Path &  path )

inline

Construct a copy of the given path.

Path() [3/4]

Common::Path::Path ( const char *  str, char  separator = '/'  )

inline

Construct a new path from the given NULL-terminated C string.

Parameters

str	A NULL-terminated C string representing a path, e.g. "foo/bar/baz"
separator	The directory separator used in the path string. Use kNoSeparator if there is no separator. Defaults to '/'.

Path() [4/4]

Common::Path::Path ( const String &  str, char  separator = '/'  )

inlineexplicit

Construct a new path from the given String. This is explicit to limit mixing strings and paths in the codebase.

Parameters

str	A String representing a path, e.g. "foo/bar/baz"
separator	The directory separator used in the path string. Use kNoSeparator if there is no separator. Defaults to '/'.

Member Function Documentation

toString()

String Common::Path::toString

(

char

separator = '/'

)

const

Converts a path to a string using the given directory separator. Collisions in resulting path are checked and warned once.

Parameters

separator

The character used to separate directory names. kNoSeparator must not be used here. Defaults to '/'.

clear()

void Common::Path::clear ( )

inline

Clears the path object

getParent()

Path Common::Path::getParent

(

)

const

Returns the Path for the parent directory of this path.

Appending the getLastComponent() of a path to getParent() returns a path identical to the original path.

getLastComponent()

Path Common::Path::getLastComponent

(

)

const

Returns the last component of this path.

Appending the getLastComponent() of a path to getParent() returns a path identical to the original path.

baseName()

String Common::Path::baseName

const

Returns the last non-empty component of this path. Compared to getLastComponent(), baseName() doesn't return the trailing / if any.

Member Data Documentation

kNoSeparator

const char Common::Path::kNoSeparator = '\x00'
