SoInput — used to read Inventor data files

       This  class is used by the SoDB reading routines when reading Inventor data files. It supports both ASCII
       (default) and binary Inventor formats. Users can  also  register  additional  valid  file  headers.  When
       reading,  SoInput  skips over Inventor comments (from '#' to end of line) and can stack input files. When
       EOF is reached, the stack is popped. This class can also be used to read from a buffer in memory.

       SoInput

SoInput()~SoInput()
          Constructor and destructor. The default SoInput reads from stdin.  The  destructor  closes  any  files
          opened by the SoInput.

     staticvoidaddDirectoryFirst(constchar*dirName)staticvoidaddDirectoryLast(constchar*dirName)staticvoidaddEnvDirectoriesFirst(constchar*envVarName)staticvoidaddEnvDirectoriesLast(constchar*envVarName)
          The  SoInput  class maintains a global list of directories that is searched to find files when opening
          them. Directories are searched in order. Each of these routines adds directories to the  list,  either
          at  the  beginning  ("First")  or the end ("Last"). The last two routines add directories named in the
          value of the given environment variable. Directories may be separated by colons or whitespace  in  the
          variable's value.

     staticvoidremoveDirectory(constchar*dirName)
          Removes named directory from the list.

     staticvoidclearDirectories()
          Clears the list of directories (including the current directory).

     staticconstSbStringList&getDirectories()
          Returns the list of directories as an SbStringList.

     voidsetFilePointer(FILE*newFP)
          Sets file pointer to read from. Clears the stack of input files if necessary.

     SbBoolopenFile(constchar*fileName,SbBoolokIfNotFound=FALSE)
          Opens  named  file,  sets  file  pointer to result. Clears the stack of input files if necessary. This
          returns FALSE on error; if okIfNotFound is FALSE (the default), this prints an error  message  if  the
          file could not be found.

     SbBoolpushFile(constchar*fileName)
          Opens named file, pushing the resulting file pointer onto the stack. Returns FALSE on error.

                                  closeFile()
          Closes all files on stack opened with openFile() or pushFile().

     SbBoolisValidFile()
          Returns  TRUE  if  the  currently  open file is a valid Inventor file; that is, it begins with a valid
          Inventor header, or one that has been registered with SoDB::registerHeader.

     FILE*getCurFile()const
          Returns a pointer to the current file, or NULL if reading from a buffer.

     constchar*getCurFileName()const
          Returns full name (including directory path) of current file, or NULL if reading from a buffer.

     voidsetBuffer(void*bufPointer,size_tbufSize)
          Sets an in-memory buffer to read from, along with its size.

     SbStringgetHeader()
          Returns the header of the file being read.

     floatgetIVVersion()
          Returns the Inventor file version of the file being  read  (e.g.  2.1).  If  the  file  has  a  header
          registered  through  SoDB::registerHeader(),  the  returned version is the Inventor version registered
          with the header.
