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
