All Implemented Interfaces:

B2JsonTypeHandler<T>

public class B2JsonUnionBaseHandler<T>
extends B2JsonTypeHandlerWithDefaults<T>

Handler for the class that is the base class for a union type.

This handler is used only for deserialization, where it finds the type name in the JSON object, and this dispatches to the subclass for that type.

Method Summary

Modifier and Type	Method	Description
protected void	checkDefaultValues()	Check the validity of the default value, if there is one.
T	defaultValueForOptional()	Returns the default value to use when an optional field is not present.
T	deserialize(B2JsonReader in, B2JsonOptions options)	Deserialize one object from a JSON input stream.
T	deserializeUrlParam(java.lang.String urlValue)	When an API is called with GET, this is used to deserialize one of the values.
java.lang.reflect.Type	getHandledType()	What class does this handle?
protected void	initializeImplementation(B2JsonHandlerMap b2JsonHandlerMap)	Does any initialization specific to the concrete class.
boolean	isStringInJson()	Does this type look like a string in JSON?
void	serialize(T obj, B2JsonOptions options, B2JsonWriter out)	Serialize one object of the class to a JSON output stream.

protected void initializeImplementation(B2JsonHandlerMap b2JsonHandlerMap)
                                 throws B2JsonException

Description copied from class: B2JsonInitializedTypeHandler

Does any initialization specific to the concrete class. Override in classes that need to gather information from other handlers.

Throws:

B2JsonException

checkDefaultValues

protected void checkDefaultValues()
                           throws B2JsonException

Check the validity of the default value, if there is one.

Specified by:

checkDefaultValues in class B2JsonTypeHandlerWithDefaults<T>

Throws:

B2JsonException - if there is a problem

getHandledType

public java.lang.reflect.Type getHandledType()

Description copied from interface: B2JsonTypeHandler

What class does this handle?

Returns:

serialize

public void serialize(T obj,

                      B2JsonWriter out)
               throws java.io.IOException,
                      B2JsonException
