I find some java code to call the grass commond,i am confusing with some parmeters:

/**

  • Define all environment variables needed by Grass
  • @param gisBase
  • Directory where GRASS lives.
  • @param gisRcreate
  • Define if an existing GISRC file as to be used.
  • @param gisRc
  • Name of .grassrc6 file. GISRCRC defines the system wide value
  • while in a GRASS session.
  • @param mapset
  • Initial mapset directory which is a subdirectory of
  • LOCATION_NAME
  • @param location
  • Initial location directory which is a subdirectory of GISDBASE
  • @param gisDBase
  • Initial database directory which should be a fully qualified
  • path (eg /usr/local/share/grassdata).
  • @param proj
  • Projection code.
    */
    public void setEnv(String gisBase, String gisRcreate, String gisRc,
    String mapset, String location, String gisDBase, String proj)

what is the difference between gisRcreate and the gisRc
