Method Detail

defineEntries

public static Map defineEntries(Map map,
                List<String> declarations)

Define new entries in map from all declaration strings in declarations. For every string in the collection, defineEntries(Map, String) is called.

Parameters:

map - The map to receive the new declarations

declarations - A collection of declaration strings.

Returns:

The parameter map

defineEntries

public static Map defineEntries(Map map,
                String definition)

Define new entries in map from declarations. For the "declarations" syntax see ReaderTools.readEntry(java.io.Reader, char).

Parameters:

map - The map to receive the new declarations

declarations - A collection of declaration strings.

Returns:

The parameter map

get

public static Object get(Map map,
         Object key,
         Object defaultValue)

get

public static String get(Map map,
         Object key,
         String defaultValue)

toStringDeep

public static String toStringDeep(Map<String,?> map)

toStringDeep

public static void toStringDeep(Map<String,?> map,
                String prefix,
                StringBuilder sb)

Serialize the Map to a String. This is done recursively, i.e. all Map substructures are converted, too. The result is a String where the keys are path names. Example, .

 {
   a = "b"
   x = {
     i = 12
     j = {
       last = "nn"
     }
   }
 }
 

will result in

 a="b";x.i="12";x.j.last="nn"
 

Parameters:

map -
