 OSD_Path ()
 Creates a Path object initialized to an empty string. i.e. current directory. More...
 
 OSD_Path (const TCollection_AsciiString &aDependentName, const OSD_SysType aSysType=OSD_Default)
 Creates a Path object initialized by dependant path. ex: OSD_Path me ("/usr/bin/myprog.sh",OSD_UnixBSD);. More...

 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":/users/examples On VMS sparc4"sga secret_passwd"::$5$dkb100:[users.examples] Sets each component of a Path giving its system dependent name.

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 dependant 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.]"
