Detailed Description

System tools for file system introspection.

A class with only static methods for doing parallel file system introspection. It limits doing file stats on process 0 and broadcasting the results to other processes. It is built on VTK's SystemTools class and uses the global controller for communication. It uses blocking collective communication operations.

New()

static vtkPSystemTools * vtkPSystemTools::New ( )

static

IsTypeOf()

static vtkTypeBool vtkPSystemTools::IsTypeOf ( const char *  type )

static

IsA()

virtual vtkTypeBool vtkPSystemTools::IsA ( const char *  name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

SafeDownCast()

static vtkPSystemTools * vtkPSystemTools::SafeDownCast ( vtkObjectBase *  o )

NewInstanceInternal()

virtual vtkObjectBase * vtkPSystemTools::NewInstanceInternal ( ) const

protectedvirtual

NewInstance()

const

PrintSelf()

void vtkPSystemTools::PrintSelf ( ostream &  os, vtkIndent  indent  )

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

BroadcastString()

static void vtkPSystemTools::BroadcastString ( std::string &  , int  proc  )

static

Given a string on process proc, broadcast that string to all of the other processes.

This method does not have a correspondence to anything in SystemTools.

CollapseFullPath() [1/2]

static VTK_FILEPATH std::string vtkPSystemTools::CollapseFullPath ( VTK_FILEPATH const std::string &  in_relative )

static

Given a path to a file or directory, convert it to a full path.

This collapses away relative paths relative to the cwd argument (which defaults to the current working directory). The full path is returned.

CollapseFullPath() [2/2]

static VTK_FILEPATH std::string vtkPSystemTools::CollapseFullPath ( VTK_FILEPATH const std::string &  in_relative, VTK_FILEPATH const char *  in_base  )

static

FileExists() [1/4]

static bool vtkPSystemTools::FileExists ( VTK_FILEPATH const char *  filename, bool  isFile  )

static

Return true if a file exists in the current directory.

If isFile = true, then make sure the file is a file and not a directory. If isFile = false, then return true if it is a file or a directory. Note that the file will also be checked for read access. (Currently, this check for read access is only done on POSIX systems.)

FileExists() [2/4]

static bool vtkPSystemTools::FileExists ( VTK_FILEPATH const std::string &  filename, bool  isFile  )

static

Return true if a file exists in the current directory.

If isFile = true, then make sure the file is a file and not a directory. If isFile = false, then return true if it is a file or a directory. Note that the file will also be checked for read access. (Currently, this check for read access is only done on POSIX systems.)

FileExists() [3/4]

static bool vtkPSystemTools::FileExists ( VTK_FILEPATH const char *  filename )

static

Return true if a file exists in the current directory.

If isFile = true, then make sure the file is a file and not a directory. If isFile = false, then return true if it is a file or a directory. Note that the file will also be checked for read access. (Currently, this check for read access is only done on POSIX systems.)

FileExists() [4/4]

static bool vtkPSystemTools::FileExists ( VTK_FILEPATH const std::string &  filename )

static

Return true if a file exists in the current directory.

If isFile = true, then make sure the file is a file and not a directory. If isFile = false, then return true if it is a file or a directory. Note that the file will also be checked for read access. (Currently, this check for read access is only done on POSIX systems.)

FileIsDirectory()

static bool vtkPSystemTools::FileIsDirectory ( VTK_FILEPATH const std::string &  name )

static

Return true if the file is a directory.

FindProgramPath()

static bool vtkPSystemTools::FindProgramPath ( const char *  argv0, std::string &  pathOut, std::string &  errorMsg, const char *  exeName = nullptr, const char *  buildDir = nullptr, const char *  installPrefix = nullptr  )

static

Given argv[0] for a unix program find the full path to a running executable.

argv0 can be null for windows WinMain programs in this case GetModuleFileName will be used to find the path to the running executable. If argv0 is not a full path, then this will try to find the full path. If the path is not found false is returned, if found true is returned. An error message of the attempted paths is stored in errorMsg. exeName is the name of the executable. buildDir is a possibly null path to the build directory. installPrefix is a possibly null pointer to the install directory.

GetCurrentWorkingDirectory()

static VTK_FILEPATH std::string vtkPSystemTools::GetCurrentWorkingDirectory ( bool  collapse = true )

static

Get current working directory CWD.

GetProgramPath()

static VTK_FILEPATH std::string vtkPSystemTools::GetProgramPath ( VTK_FILEPATH const std::string &  )

static

Given the path to a program executable, get the directory part of the path with the file stripped off.

If there is no directory part, the empty string is returned.
