On first start, calling this method with an argument map and a string key, the user is asked to input the correct key setting on the command line. If the command line query is non-null, this line is printed, otherwise only the key is echoed.

jask

public static void jask(Map<String,String> prop,
                        String key,
                        String query)

Displays a dialog for input of string answers. A workaround for os, where there is only limited access to standard in.

loadNormalOrder

public static Map<String,String> loadNormalOrder(String res)

Tries to read properties from the default locations ion the following order: First config, then home, last current. If retrieval is not possible from any of these sources, we return null. If retrieval is successful, the appropriate boolean is set in the properties returned.

saveNormalOrder

public static boolean saveNormalOrder(PropertyBearing prop,
                                      String res,
                                      String remark)

Save the properties in normal order: First config, then home, last current. If saving is possible, the appropriate flag is set.

propertiesFromConfig

public static Map<String,String> propertiesFromConfig(String res)

Tries to read from home directory the stated property bearing definitions. If the resource cannot be found, null is returned.

propertiesFromHome

public static Map<String,String> propertiesFromHome(String res)

Tries to read from home directory the stated property bearing definitions. If the resource cannot be found, null is returned.

propertiesFromCurrent

public static Map<String,String> propertiesFromCurrent(String res)

Tries to read from current directory the stated property bearing definitions. If the resource cannot be found, null is returned.
