Class JSONPojoConvertor

java.lang.Object
  org.eclipse.jetty.util.ajax.JSONPojoConvertor

All Implemented Interfaces:

JSON.Convertor

public class JSONPojoConvertor
extends Object
implements JSON.Convertor

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
