Detailed Description

class chemin definition

Note

"chemin" means path in French, this class implements path objects. There is no relative/absolute caracteristics in these objects, Only at display() time one can decide to given a string representing the path as either absolute or relative.

Examples

/home/denis/Telechargements/WEBDAR/webdar-1.0.2/src/html_form_input_file.hpp.

Member Function Documentation

back()

std::string chemin::back ( ) const

inline

get the last member of the path

Note

if the path is empty() an exception_range is thrown

clear()

void chemin::clear ( )

inline

default copy constructor is OK

default assignement operator is OK too default destructor is also fine here set the path as an empty path

front()

std::string chemin::front ( ) const

inline

get the first member of the path

Note

if the path is empty() an exception_range is thrown

get_index()

unsigned int chemin::get_index ( ) const

inline

return the index of the path

Note

the index is a pointer to a member of the path. Zero is the first member the index can be modified at will even on const objects, but always points to a valid member of the path. If the path is empty, playing with index raises an exception

namify()

string chemin::namify

(

)

const

return a compact string to be used as identifier.

Note

Two different path give two different strings, two equal path give the same identifier

operator[]()

const string & chemin::operator[]

(

unsigned int

x

)

const

access to a given member of the path

Parameters

[in]

x

index of the path to retrieve. This argument value must range from zero to size-1

Returns

the requested member of the path

Note

if called on an empty path, an exception is thrown.

pop_front()

void chemin::pop_front

(

)

removes the first member of the path from this object (root side)

Note

throws an exception if the path is empty
