Detailed Description

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 exit.

A complete path name is made of:

A device name: some system manage path names that refer to objects located on different physical devices. Typically, the Windows operating system stores it system files on a device called C:.
A directory part: this contains the path, from the device root, to the object itself.
A file name: if the path name refers to a file, this holds the name of this file.
An extension: operating systems use file name extensions to identify different types of files, trigger actions or sort the files.

IlPathName objects can be absolute or relative paths.

Member Enumeration Documentation

enum IlPathName::IlPathType

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.

Enumerator

SystemPathType

The syntax of the actual system.

The directory separator character that is used is the one of the system you are running on.

UnixPathType

The syntax of the Unix-like systems.

The directory separator character is a slash ('/').

DosPathType

The syntax of the DOS-like systems.

The directory separator character is a backslash ('\').

enum IlPathName::SortMode

Path names sorting options.

Higher-level objets can sort IlPathName objects. This enumeration allows for customizing how this sort is performed.

Enumerator
SortNone	No sort on the path name is done.
SortAlphabetically	Path names are sorted alphabetically.
SortCaseInsensitive	Path names are sorted alphabetically, but in a case-insentitive manner.
SortReverse	Path names are sorted in a reverse order.
GroupDirectories	Paths identifying directories are grouped together.
GroupExtensions	Paths identifying files with the same extension are grouped together.

Constructor & Destructor Documentation

IlPathName::IlPathName ( )

Initializes an empty IlPathname object.

All the fields are empty.

See Also: IlPathName(const IlString&).; IlPathName(const char*).; IlPathName(const IlPathName&).

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:

    IlPathName pathname1("/Dev/Rogue Wave/Views/file.ilv");
    IlString path1(pathname1);
    // On a Windows system, path1 is "\Dev\Rogue Wave\Views\file.ilv"
    IlPathName pathname2("/Dev//Rogue Wave/Views/file.ilv");
    IlString path2(pathname2);
    // On a Windows system, path2 is "\Dev\Rogue Wave\Views\file.ilv":
    // the double slash character was replaced by a single one.
    IlPathName pathname3("/Dev//Rogue Wave/DB Link/../Views/file.ilv");
    IlString path3(pathname3);
    // On a Windows system, path3 is "\Dev\Rogue Wave\Views\file.ilv":
    // Note how the fragment 'DB Link/../' was properly removed.
    IlPathName pathname4("/Dev//Rogue Wave/./Views/file.ilv");
    IlString path4(pathname4);
    // On a Windows system, path4 is "\Dev\Rogue Wave\Views\file.ilv":
    // The useless fragment './' was removed.

Parameters

path	The path that initializes this object.

See Also: IlPathName().; IlPathName(const char*).; IlPathName(const IlPathName&).

IlPathName::IlPathName ( const char * path )

Initializes an IlPathname object from a C-style string.

The string is copied.

Parameters

path	The path that initializes this object.

See Also: IlPathName().; IlPathName(const IlString&).; IlPathName(const IlPathName&).

IlPathName::IlPathName ( const IlPathName & path )

Copy constructor.

Parameters

path	The source path name that is copied.

See Also: IlPathName().; IlPathName(const IlString&).; IlPathName(const char*).

Member Function Documentation

		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:

    IlPathName pathname("D:\\Dev\\Rogue Wave\\");
    pathname.addDirectory("a\\b\\");
    // pathname is now "D:\Dev\Rogue Wave\a\b\"

Parameters

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.

See Also: 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.

Parameters

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.

IlBoolean IlPathName::changeCurrentDirectory ( ) const

Changes the current directory to this path name.

Returns: IlFalse if an error occurs and IlTrue if the operation is successful.

See Also: QueryCurrentDirectory() queryCurrentDirectory().

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.

Parameters

newMode The new mode that is set to the object referenced by this path name object, as defined in the "C" function chmod.

Returns: IlTrue if the method succeeds and IlFalse if an error occurs.

See Also: 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.

Returns: IlTrue if the method succeeds and IlFalse if an error occurs.

See Also: 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 pathname1("D:\\Dev\\Rogue Wave\\Views\\file.ilv");
    pathname1.computeAllButLastSubDirectory();
    // pathname1 is 'D:\Dev\Rogue Wave\'
    IlPathName pathname2("C:\\");
    pathname2.computeAllButLastSubDirectory();
    // pathname2 is 'C:\'

Returns: The resulting IlPathName object.

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:

    IlPathName path1("D:\\Dev\\Rogue Wave\\Views\\somefile.txt");
    IlPathName other1("D:\\Dev\\Rogue Wave\\DB Link\\somefile.txt");
    path1.computeDifferLeading(other1);
    // path1 is "Views\somefile.txt" (same leading directories)
           
    IlPathName path2("D:\\Dev\\Rogue Wave\\Views\\file.ilv");
    IlPathName other2("C:\\windows\\system32\\xcopy.exe");
    path2.computeDifferLeading(other2);

    // path2 is ".\" (no directory)

Returns: The current, modified object.

See Also: 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.

Returns: The number of sub-directories stored in this object.

See Also: 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:

    IlPathName pathname1("D:\\Dev\\Rogue Wave\\");
    IlPathName relative1("D:\\Dev\\");
    pathname1.computeRelativePath(relative1);
    // pathname1 is 'Rogue Wave\'
    IlPathName pathname2("D:\\Dev\\Rogue Wave\\");
    IlPathName relative2("D:\\Dev\\Rogue Wave\\Views\\data\\");
    pathname2.computeRelativePath(relative2);
    // pathname2 is '..\..\'    

Parameters

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).

Returns: The resulting IlPathName object, that holds the computed relative path.

IlPathName& IlPathName::computeSameLeading ( const IlPathName & path )

Computes the part that is common at the beginning of two path names.

Example, on a Windows machine:

    IlPathName path2("D:\\Dev\\Rogue Wave\\Views\\file.ilv");
    IlPathName other2("C:\\windows\\system32\\xcopy.exe");
    path2.computeSameLeading(other2);
    // path2 is ".\" (nothing in common)

Example, on a Windows machine:

    IlPathName path1("D:\\Dev\\Rogue Wave\\Views\\somefile.txt");
    IlPathName other1("D:\\Dev\\Rogue Wave\\DB Link\\somefile.txt");
    path1.computeSameTrailing(other1);

    // path2 is ".\" (nothing in common)

Parameters

path	The path name to compare with.

Returns: The current, modified object.

See Also: 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.

Warning: The returned string must be deleted with the delete[] operator when it is not used any more.

Returns: A new C-style string, allocated with new[], that contains an SFN-like version of this path name.

See Also: get83DosValue(), getDosValue().

char* IlPathName::copyBaseName ( ) const

Returns a copy of the file name and the extension parts of this IlPathname.

Warning: The returned string must be deleted with the delete[] operator when it is not used any more.

Returns: A new C-style string, allocated with new[], that contains the file name and the extension parts of this path name.

See Also: getBaseName().

char* IlPathName::copyDevice ( ) const

Returns a copy of the device part of this IlPathname.

Warning: The returned string must be deleted with the delete[] operator when it is not used any more.

Returns: A new C-style string, allocated with new[], that contains the device part of this path name.

See Also: getDevice().

char* IlPathName::copyDirectory	(	IlBoolean	finalSep = `IlTrue`,
		IlPathType	type = `SystemPathType`
	)		const

Returns a copy of the directory part of this IlPathname.
