Method Detail

newAssosiativeArrayMap

public static java.util.Map<java.lang.Integer,java.util.Map<java.lang.String,java.lang.String>> newAssosiativeArrayMap()

Factory method for Map that acts like a javascript associative array. This Map is the counterpart for the associative array in js. For instance: in js you can create and fetch associative arrays like this:

 $arrayObj[0]['firstName'] = 'Albert';
 $arrayObj[0]['lastName'] = 'Einstein';
 $arrayObj[1]['firstName'] = 'Neil';
 $arrayObj[0]['lastName'] = 'Armstrong';
 

With this method you can do the same like this:

 final Map<Integer, Map<String, String>> arrayMap = MapExtensions.newAssosiativeArrayMap();

 arrayMap.get(0).put("firstName", "Albert");
 arrayMap.get(0).put("lastName", "Einstein");
 arrayMap.get(1).put("firstName", "Neil");
 arrayMap.get(1).put("lastName", "Armstrong");
 

Returns:

The Map that acts like a javascript associative array
