 OSD_Path ()
 Creates a Path object initialized to an empty string. i.e. current directory.
 
 OSD_Path (const TCollection_AsciiString &aDependentName, const OSD_SysType aSysType=OSD_Default)
 Creates a Path object initialized by dependent path. ex: OSD_Path me ("/usr/bin/myprog.sh",OSD_UnixBSD);.
 
 OSD_Path (const TCollection_AsciiString &aNode, const TCollection_AsciiString &aUsername, const TCollection_AsciiString &aPassword, const TCollection_AsciiString &aDisk, const TCollection_AsciiString &aTrek, const TCollection_AsciiString &aName, const TCollection_AsciiString &anExtension)
 Initializes a system independent path. By default , the Path conversion will be assumed using currently used system. A special syntax is used to specify a "aTrek" in an independent manner : a "|" represents directory separator a "^" means directory above (father) examples: "|usr|bin" - On UNIX -> "/usr/bin".
 
void Values (TCollection_AsciiString &aNode, TCollection_AsciiString &aUsername, TCollection_AsciiString &aPassword, TCollection_AsciiString &aDisk, TCollection_AsciiString &aTrek, TCollection_AsciiString &aName, TCollection_AsciiString &anExtension) const
 Gets each component of a path.
 
void SetValues (const TCollection_AsciiString &aNode, const TCollection_AsciiString &aUsername, const TCollection_AsciiString &aPassword, const TCollection_AsciiString &aDisk, const TCollection_AsciiString &aTrek, const TCollection_AsciiString &aName, const TCollection_AsciiString &anExtension)
 Sets each component of a path.
 
void SystemName (TCollection_AsciiString &FullName, const OSD_SysType aType=OSD_Default) const
 Returns system dependent path <aType> is one among Unix,VMS ... This function is not private because you may need to display system dependent path on a front-end. It can be useful when communicating with another system. For instance when you want to communicate between VMS and Unix to transfer files, or to do a remote procedure call using files. example : OSD_Path myPath ("sparc4", "sga", "secret_passwd", "$5$dkb100","|users|examples"); Internal ( Dependent_name ); On UNIX sga"secret_passwd"@sparc4:/users/examples On VMS sparc4"sga secret_passwd"::$5$dkb100:[users.examples] Sets each component of a Path giving its system dependent name.
 
void ExpandedName (TCollection_AsciiString &aName)
 Returns system dependent path resolving logical symbols.
 
void UpTrek ()
 This removes the last directory name in <aTrek> and returns result. ex: me = "|usr|bin|todo.sh" me.UpTrek() gives me = "|usr|todo.sh" if <me> contains "|", me.UpTrek() will give again "|" without any error.
 
void DownTrek (const TCollection_AsciiString &aName)
 This appends a directory name into the Trek. ex: me = "|usr|todo.sh" me.DownTrek("bin") gives me = "|usr|bin|todo.sh".
 
Standard_Integer TrekLength () const
 Returns number of components in Trek of <me>. ex: me = "|usr|sys|etc|bin" me.TrekLength() returns 4.
 
void RemoveATrek (const Standard_Integer where)
 This removes a component of Trek in <me> at position <where>. The first component of Trek is numbered 1. ex: me = "|usr|bin|" me.RemoveATrek(1) gives me = "|bin|" To avoid a 'NumericError' because of a bad <where>, use TrekLength() to know number of components of Trek in <me>.
 
void RemoveATrek (const TCollection_AsciiString &aName)
 This removes <aName> from <me> in Trek. No error is raised if <aName> is not in <me>. ex: me = "|usr|sys|etc|doc" me.RemoveATrek("sys") gives me = "|usr|etc|doc".
 
TCollection_AsciiString TrekValue (const Standard_Integer where) const
 Returns component of Trek in <me> at position <where>. ex: me = "|usr|bin|sys|" me.TrekValue(2) returns "bin".
 
void InsertATrek (const TCollection_AsciiString &aName, const Standard_Integer where)
 This inserts <aName> at position <where> into Trek of <me>. ex: me = "|usr|etc|" me.InsertATrek("sys",2) gives me = "|usr|sys|etc".
 
TCollection_AsciiString Node () const
 Returns Node of <me>.
 
TCollection_AsciiString UserName () const
 Returns UserName of <me>.
 
TCollection_AsciiString Password () const

Constructor & Destructor Documentation

◆ OSD_Path() [1/3]

OSD_Path::OSD_Path ( )

Creates a Path object initialized to an empty string. i.e. current directory.

◆ OSD_Path() [2/3]

OSD_Path::OSD_Path ( const TCollection_AsciiString & aDependentName,
const OSD_SysType aSysType = OSD_Default )

Creates a Path object initialized by dependent path. ex: OSD_Path me ("/usr/bin/myprog.sh",OSD_UnixBSD);.

OSD_Path me ("sys$common:[syslib]cc.exe",OSD_OSF) will raise a ProgramError due to invalid name for this type of system. In order to avoid a 'ProgramError' , use IsValid(...) to ensure you the validity of <aDependentName>. Raises ConstructionError when the path is either null or contains characters not in range of ' '...'~'.

◆ OSD_Path() [3/3]

OSD_Path::OSD_Path ( const TCollection_AsciiString & aNode,
const TCollection_AsciiString & aUsername,
const TCollection_AsciiString & aPassword,
const TCollection_AsciiString & aDisk,
const TCollection_AsciiString & aTrek,
const TCollection_AsciiString & aName,
const TCollection_AsciiString & anExtension )

Initializes a system independent path. By default , the Path conversion will be assumed using currently used system. A special syntax is used to specify a "aTrek" in an independent manner : a "|" represents directory separator a "^" means directory above (father) examples: "|usr|bin" - On UNIX -> "/usr/bin".

  • On VMS -> "[usr.bin]"
  • On MSDOS-> "\usr\bin"
  • On MacOs-> ": usr : bin"

"^|rep" - On UNIX -> "../rep"

  • On VMS -> "[-.rep]"
  • On MSDOS -> "..\rep"
  • On MacOS-> ":: rep"

"subdir|" - On UNIX -> "subdir/"

  • On VMS -> "[.subdir.]"
