public Class JSONPojoConvertor

Class Inheritance

extends Object
implements Convertor

java.lang.Object
org.mortbay.util.ajax.JSONPojoConvertor

All Implemented Interfaces

org.mortbay.util.ajax.JSON.Convertor

Imports

java.lang.reflect.Array, .InvocationTargetException, .Method, .Modifier, java.util.Arrays, .HashMap, .HashSet, .Iterator, .Map, .Set, org.mortbay.log.Log, org.mortbay.util.ajax.JSON.Output

Converts POJOs to JSON and vice versa. The key difference: - returns the actual object from Convertor.fromJSON (JSONObjectConverter returns a Map) - the getters/setters are resolved at initialization (JSONObjectConverter resolves it at runtime) - correctly sets the number fields
