Class MapParser<VALUETYPE>

  • public abstract class MapParser<VALUETYPE>
extends SimpleMapParser

    Superclasses of parsers of a map represented textually as {key1:value1,"anystringkey":value2,'anystringkey2':value3 ...}. This parser must be extended to override the way values are parsed and constructed.

    Example: To create a Double map parser:

     public static final class DoubleMapParser extends MapParser<Double> {

     @Override
     protected Double parseValue(String value) {
         return Double.parseDouble(value);
     }

 }

    Map parsers are NOT multithread safe, but are cheap to construct.
