Method Detail

g_list

public java.util.Enumeration g_list(int type)
                             throws GRASSException

Attempts to emulate behaviour of g.list command in a way that its output can be useful in Java applications. Mostly intended for providing list of file names for user interface elements. This method directly checks content of directories under GRASS database locations with respect to mapset search path. There is no certainty that algorithm used provides correct results.

Parameters:

type - types of GRASS files to list (rasters, vectors, sites)

Returns:

Enumeration of unique names of GRASS files

Throws:

GRASSException - Exception with an appropriate error message is thrown in case (1) of unpredictable situation and (2) I/O problem
