MapParser (vespajlib 7.179.11 API)

java.lang.Object
- com.yahoo.text.SimpleMapParser
- - com.yahoo.text.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.

parseToMap

public java.util.Map<java.lang.String,VALUETYPE> parseToMap(java.lang.String s)

Convenience method doing return parse(s,new HashMap<String,VALUETYPE>())

parse
```
public java.util.Map<java.lang.String,VALUETYPE> parse(java.lang.String string,
                                                             java.util.Map<java.lang.String,VALUETYPE> map)
```

Parameters:

string - the textual representation of the map

map - the map to which the values will be added

Returns:

the input map instance for convenience
