Class that manages path names in a portable way.
Library: ilog
Usually, a path name is used to locate a file or a directory in a file system. However, the file or path corresponding to a given IlPathName
does not necessarily exist.
A complete path name is made of:
C:
.IlPathName
to store the server and share names: \\server\share
. This is not used when running on Unix systems. IlPathName
objects can be absolute or relative paths.
The different types of path names.
This type indicates the syntax of a path name when it is translated into a string. In particular, it decides whether the directory separator character should be a slash, as on Unix, or a backslash, as on DOS.
enum IlPathName::SortMode |
Path names sorting options.
Higher-level objets can sort IlPathName
objects. This enumeration allows for customizing how this sort is performed.
IlPathName::IlPathName | ( | ) |
Initializes an empty IlPathname
object.
All the fields are empty.
IlPathName::IlPathName | ( | const IlString & | path | ) |
Initializes an IlPathname
object from an IlString
.
The string is parsed to initialize a new IlPathname
the way you would expect: relative path names are resolved, empty segments are removed, and so on.
Example, on a Windows machine:
path | The path that initializes this object. |
IlPathName::IlPathName | ( | const char * | path | ) |
Initializes an IlPathname
object from a C-style string.
The string is copied.
path | The path that initializes this object. |
IlPathName::IlPathName | ( | const IlPathName & | path | ) |
Copy constructor.
path | The source path name that is copied. |
void IlPathName::addDirectory | ( | const IlString & | directory, |
int | end = -1 , |
||
IlPathType | type = SystemPathType , |
||
int | start = 0 |
||
) |
Appends a directory to this IlPathName
.
directory must be a relative path (not beginning with a directory separator), or the result is undefined.
Example, on a Windows machine:
directory | The directory to append to the current path name. |
end | The index of the last character to use from directory. The default value of -1 indicates down to the end of the string. |
type | The syntax (system, Unix or DOS) that the provided string is using. The default is SystemPathType . |
start | The index of the first character to take from directory. The default value of 0 indicates the first character of the string. |
getDirectory()
. void IlPathName::addDosDirectory | ( | const IlString & | directory, |
int | end = -1 , |
||
int | start = 0 |
||
) |
Appends a directory to this IlPathName
.
directory must be a relative path (not beginning with a backslash character), and in the DOS syntax or the result is undefined.
directory | The directory to append to the current path name. |
end | The index of the last character to use from directory. The default value of -1 indicates down to the end of the string. |
start | The index of the first character to take from directory. The default value of 0 indicates the first character of the string. |
addDirectory()
, addUnixDirectory()
. getDosDirectory()
. void IlPathName::addUnixDirectory | ( | const IlString & | directory, |
int | end = -1 , |
||
int | start = 0 |
||
) |
Appends a directory to this IlPathName
.
directory must be a relative path (not beginning with a slash character), and in the Unix syntax or the result is undefined.
directory | The directory to append to the current path name. |
end | The index of the last character to use from directory. The default value of -1 indicates down to the end of the string. |
start | The index of the first character to take from directory. The default value of 0 indicates the first character of the string. |
addDirectory()
, addDosDirectory()
. getUnixDirectory()
. IlBoolean IlPathName::changeCurrentDirectory | ( | ) | const |
Changes the current directory to this path name.
IlFalse
if an error occurs and IlTrue
if the operation is successful. IlBoolean IlPathName::changeMode | ( | short | newMode | ) | const |
Changes permissions of the object referenced by this IlPathName
.
The value depends on the system. If an error occurs, then the functions returns IlFalse
, IlTrue
otherwise.
newMode | The new mode that is set to the object referenced by this path name object, as defined in the "C" function chmod . |
IlTrue
if the method succeeds and IlFalse
if an error occurs. queryMode()
. IlBoolean IlPathName::closeDir | ( | ) | const |
Closes this IlPathName
.
The current path name must have been opened using openDir()
before this method is invoked. When this method returns, you must not invoke readDir()
or rewindDir
any more.
IlTrue
if the method succeeds and IlFalse
if an error occurs. openDir()
, readDir()
, rewindDir()
. IlPathName& IlPathName::computeAllButLastSubDirectory | ( | ) |
Replaces this IlPathName
by its directory part, except the last level.
The file name part is dropped from this object.
If the directory part has no sub-directory (it refers to a device root directory) then it is not modified.
Example, on a Windows machine:
IlPathName& IlPathName::computeDifferLeading | ( | const IlPathName & | path | ) |
Computes the part that is different from the beginning of two path names.
This method stores the part of the two path names that in common, the the end of them.
Example, on a Windows machine:
path | The path name to compare with. |
computeDifferTrailing()
. computeSameLeading()
. IlPathName& IlPathName::computeDifferTrailing | ( | const IlPathName & | path | ) |
Computes the part that is different from the beginning of two path names.
This method stores the part of the two path names that in common, at the end of them.
Example, on a Windows machine:
path | The path name to compare with. |
computeDifferLeading()
. computeSameTrailing()
. IlPathName& IlPathName::computeFirstSubDirectory | ( | ) |
Query the top-most directory of this IlPathName
.
Example, on a Windows machine:
computeLastSubDirectory
(). IlPathName& IlPathName::computeLastSubDirectory | ( | ) |
Query the bottom-most directory of this IlPathName
.
Example, on a Windows machine:
computeFirstSubDirectory
(). int IlPathName::computeLevelNumber | ( | ) | const |
Computes the number of levels of the current path.
This value is the number of sub-directories this IlPathName
is made of.
getTruncatedValue()
. IlPathName& IlPathName::computeRelativePath | ( | const IlPathName & | path | ) |
Computes the relative path of the current path name, relative to another IlPathName
.
The current object is assigned a relative path that is such that if it were appended to path, the resulting value would be the initial value of the current path name object.
Example, on a Windows machine:
path | The path name to compute the relative path from. Note that this must be a directory (its value should end with a directory separator). |
IlPathName& IlPathName::computeSameLeading | ( | const IlPathName & | path | ) |
Computes the part that is common at the beginning of two path names.
Example, on a Windows machine:
path | The path name to compare with. |
computeSameTrailing()
. computeDifferLeading()
. IlPathName& IlPathName::computeSameTrailing | ( | const IlPathName & | path | ) |
Computes the part that is common at the end of two path names.
Example, on a Windows machine:
path | The path name to compare with. |
computeSameLeading()
. computeDifferLeading()
. char* IlPathName::copy83DosValue | ( | ) | const |
Returns a copy of the content of this IlPathname
, truncated to 8.3 names, in the DOS syntax.
This method is equivalent to get83DosValue().copyValue();
.
This method builds a SFN version of the current path name, in the DOS syntax. If the path name is empty, it returns .\
.
Note: The truncation is actually the result of removing the trailing characters of each part of the path name, if necessary. It leaves a maximum of eight characters for each part, and three characters for the extension part. This does not follow the SFN specification (see the 8.3 filename article on Wikipedia.

Note: The truncation is actually the result of removing the trailing characters of each part of the path name, if necessary. It leaves a maximum of eight characters for each part, and three characters for the extension part. This does not follow the SFN specification (see the 8.3 filename article on Wikipedia), but has similar consequences.
