Method Details

writeObject

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

Specified by:

writeObject in interface MappingGenerator

writeObject

public MappingGenerator writeObject(Object object,
 jakarta.json.stream.JsonGenerator generator)

Description copied from interface: MappingGenerator

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"}
 

Specified by:

writeObject in interface MappingGenerator

Parameters:

object - the object to write

generator - the jsonp generator to use

Returns:

itself, for easier chaining of commands

isDedup

IllegalAccessException

Throws:

IllegalAccessException

writePrimitives

private boolean writePrimitives(Object value,
 jakarta.json.stream.JsonGenerator generator)

Returns:
