Method Details

newInstance

public Object newInstance(Class<?> c,
 JsonObject jObj,
 ReaderContext context)

Description copied from interface: JsonReader.ClassFactory

Implement this method to return a new instance of the passed in Class. Use the passed in JsonObject to supply values to the construction of the object.

Specified by:

newInstance in interface JsonReader.ClassFactory

Parameters:

c - Class of the object that needs to be created

jObj - JsonObject (if primitive type do jObj.getPrimitiveValue();

context - ReaderContext for creating objects an getting read options

Returns:

a new instance of C. If you completely fill the new instance using the value(s) from object, and no further work is needed for construction, then override the isObjectFinal() method below and return true.

isObjectFinal

public boolean isObjectFinal()

Specified by:

isObjectFinal in interface JsonReader.ClassFactory

Returns:

true if this object is instantiated and completely filled using the contents from the Object [a JsonObject or value]. In this case, no further processing will be performed on the instance. If the object has sub-objects (complex fields), then return false so that the JsonReader will continue on filling out the remaining portion of the object.
