Since this method should typically not be called on this sub-type, default implementation simply throws an IllegalStateException.

Specified by:

withConfig in class VirtualBeanPropertyWriter

Parameters:

config - Currenct configuration; guaranteed to be SerializationConfig (just not typed since caller does not have dependency to serialization-specific types)

declaringClass - Class that contains this property writer

propDef - Nominal property definition to use

type - Declared type for the property

value

protected Object value(Object bean,

 SerializerProvider prov)
                throws Exception

Description copied from class: VirtualBeanPropertyWriter

Method called to figure out the value to serialize. For simple sub-types (such as AttributePropertyWriter) this may be one of few methods to define, although more advanced implementations may choose to not even use this method (by overriding VirtualBeanPropertyWriter.serializeAsField(Object, JsonGenerator, SerializerProvider)) and define a bogus implementation.

Specified by:

value in class VirtualBeanPropertyWriter

Throws:

Exception
