  • Constructor Details

    • MapToStringTransformer

      public MapToStringTransformer()
      Creates MapToStringTransformer with defaults: 
       mappingSequence = "=";
 separatorSequence = "&";
 nullValue = "null";

    • MapToStringTransformer

      public MapToStringTransformer(String mappingSequence, String separatorSequence, String nullValue)
      Creates MapToStringTransformer with given values
      Parameters:
      mappingSequence - sequence inserted between key and value
      separatorSequence - sequence inserted between every pair of Map entries
      nullValue - sequence inserted for every null key or value

  • Method Details

    • transform

      public String transform(Map<?,?> map)
      Transforms Map to String, representing every entry as key mappingSequence value , joined by separatorSequence

      Calls toString() for keys and values, replacing null with the value of nullValue property

      For example, if we have a map with two entries: ("key1", "1") and ("key2", "2") this method would return "key1=1&key2=2" if mappingSequence is "=" and separator sequence is "&";

      Parameters:
      map - map of arguments
      Returns:
      String resulting string
