init

protected E init(E rawInput,
                 Map<String,Object> intermediateObjects)

Description copied from class: AbstractEntityTransformer

Create the core Entity and also initialize intermediateObjects (nested objects) with core entities

Specified by:

init in class AbstractEntityTransformer<E,String,E>

intermediateObjects - the Map into which we can pre-initialize stuff

Returns:

entity object
