Interface MappingGenerator

All Known Implementing Classes:

DynamicMappingGenerator, DynamicMappingGenerator.SkipEnclosingWriteEnd, 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 getJsonGenerator() method.

Method Summary

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

Method Detail

getJsonGenerator

jakarta.json.stream.JsonGenerator getJsonGenerator()

Returns:

the JsonGenerator used internally to write the JSON output.

writeObject

MappingGenerator writeObject(Object o,
                             jakarta.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(String key,
                                     Object o,
                                     jakarta.json.stream.JsonGenerator generator)
