Constructor Detail

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 Detail

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
