Interface MappingGenerator

All Known Implementing Classes:

MappingGeneratorImpl

public interface MappingGenerator

Handles writing Json for Objects. Internally it uses a JsonGenerator to write JSON To write JSON-P structure elements you can use the JsonGenerator.

Method Summary

Modifier and Type	Method and Description
MappingGenerator	writeObject(java.lang.Object o, javax.json.stream.JsonGenerator generator) Write the given Object o into the current JSON layer.
default MappingGenerator	writeObject(java.lang.String key, java.lang.Object o, javax.json.stream.JsonGenerator generator)

Method Detail

writeObject

MappingGenerator writeObject(java.lang.Object o,
                             javax.json.stream.JsonGenerator generator)

Write the given Object o into the current JSON layer. This will not open a new json layer ('{', '}') but really just write the attributes of o to the currently opened layer. Consider you have a class

     public class Customer {
         private String firstName;
         private String lastName;
         private Address address;
         ...
     }
 

then the resulting JSON String will e.g. look like

     "firstName":"Karl", "lastName":"SomeName", "address":{"street":"mystreet"}
 

Parameters:

o - the object to write

generator - the jsonp generator to use

Returns:

itself, for easier chaining of commands

writeObject

default MappingGenerator writeObject(java.lang.String key,
                                     java.lang.Object o,
                                     javax.json.stream.JsonGenerator generator)
