getFullName

public java.lang.String getFullName()

Description copied from interface: DataStoreProvider

Returns a more descriptive name for the provider that getName. This name is provided for informational purposes only. Explamples: In a file based store may return the full name of the filename, path and filename. In a data base based store may return "server:dbname:tablename" In a WFS layer based store may return "server:layername"

Returns:

String Containing the full name of the store
