public class MergingSettableBeanProperty extends SettableBeanProperty.Delegating
SettableBeanProperty implementation that will try to access value of
the property first, and if non-null value found, pass that for update
(using JsonDeserializer.deserialize(com.fasterxml.jackson.core.JsonParser, com.fasterxml.jackson.databind.DeserializationContext, Object))
instead of constructing a new value. This is necessary to support "merging" properties.
Note that there are many similarities to SetterlessProperty, which predates
this variant; and that one is even used in cases where there is no mutator
available.

Alternative to
SettableBeanProperty.deserializeAndSet(com.fasterxml.jackson.core.JsonParser, com.fasterxml.jackson.databind.DeserializationContext, java.lang.Object) that returns
either return value of setter method called (if one is),
or null to indicate that no return value is available. |

set(Object instance,

Method called to assign given value to this property, on
specified Object.

setAndReturn(Object instance,
Object value)
Method called to assign given value to this property, on
specified Object, and return whatever delegating accessor
returned (if anything)
|
protected SettableBeanProperty |
withDelegate(SettableBeanProperty d)
Method sub-classes must implement, to construct a new instance
with given delegate.
