findInjectableValue

public abstract Object findInjectableValue(DeserializationContext ctxt,
 Object valueId,
 BeanProperty forProperty,
 Object beanInstance,
 Boolean optional)

Parameters:

ctxt - Deserialization context

valueId - Object that identifies value to inject; may be a simple name or more complex identifier object, whatever provider needs

beanInstance - Bean instance that contains property to inject, if available; null if bean has not yet been constructed.

optional - Flag used for configuring the behavior when the value to inject is not found
