Class SimpleMapParser

java.lang.Object

com.yahoo.text.SimpleMapParser

Direct Known Subclasses:

MapParser

public abstract class SimpleMapParser
extends Object

Superclasses of parsers of a map represented textually as {key1:value1,"anystringkey":value2,'anystringkey2':value3 ...}. This parser must be extended to specify how to handle the key/value pairs.

Example: To create a Double map parser:

 public static final class DoubleMapParser extends MapParser<Double> {
     private Map<String, Double> map;

     ...

     @Override
     protected Double handleKeyValue(String key, String value) {
         map.put(key, Double.parseDouble(value));
     }

 }
 

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