Constructor Detail

libvect

public libvect(libgis lg)

Intializes this object by saving pointer to GRASS library object. Loads libvect.so. libvect.so must be somewhere on LD_LIBRARY_PATH.

Parameters:

lg - Previously initialized GRASS library

libgis

Method Detail

Vect_open_old

public Mapinfo Vect_open_old(java.lang.String name,
                             java.lang.String mapset)
                      throws GRASSException

Opens the vector map name in mapset for reading. Wraps GRASS library routine:

 Vect_open_old (Map, name, mapset)
    struct Map_info *Map;
    char *name, *mapset;
 

See the GRASS 4.2 Programmer's Manual, Section 13.3. Opening and closing vector maps

Parameters:

name - existing map name

mapset - mapset name where the map resides

Throws:

GRASSException - if an error was returned by the GRASS routine

Vect_open_new

public Mapinfo Vect_open_new(java.lang.String name)
                      throws GRASSException

Opens the vector map name in the current mapset for writing. Wraps GRASS library routine:

 Vect_open_new (Map, name)
    struct Map_info *Map;
    char *name;
 

See the GRASS 4.2 Programmer's Manual, Section 13.3. Opening and closing vector maps

Parameters:

name - new map name

Throws:

GRASSException - if an error was returned by the GRASS routine

Vect_set_open_level

public void Vect_set_open_level(int level)

Allows you to specify at which level the map is to be opened. It is recommended that it only be used to force opening at level one(1). Wraps GRASS library routine:

 Vect_set_open_level (level)
    int level;
 

See the GRASS 4.2 Programmer's Manual, Section 13.3. Opening and closing vector maps

Parameters:

level - level to set
