Class JsonNumberObjectFactory

java.lang.Object
  flexjson.factories.JsonNumberObjectFactory

All Implemented Interfaces:

ObjectFactory

public class JsonNumberObjectFactory
extends Object
implements ObjectFactory

This class exists because it possible we don't have any type information to guide us to what object we should instantiate when dealing with type-less collections. When this happens its possible a JsonNumber can come through, and since we will default to the underlying type found in the JSON stream in these situations we need to convert the JsonNumber to something valid: Double or Long.

Description copied from interface: ObjectFactory

This method is called by the deserializer to construct and bind an object. At the end of this method the object should be fully constructed. ObjectBinder can be used to bind values into the object according to default rules. For simple implementations you won't need to use this, but for more complex or generic objects reusing methods like ObjectBinder.bind(Object, java.lang.reflect.Type) and ObjectBinder.bindIntoCollection(java.util.Collection, java.util.Collection, java.lang.reflect.Type).

Specified by:

instantiate in interface ObjectFactory

Parameters:

context - the object binding context to keep track of where we are in the object graph and used for binding into objects.

value - This is the value from the json object at the current path.

targetType - This is the type pulled from the object introspector. Used for Collections and generic types.

targetClass - concrete class pulled from the configuration of the deserializer.

Returns:

the fully bound object. At the end of this method the object should be fully constructed.
