public class CreatorProperty extends SettableBeanProperty
This concrete sub-class implements property that is passed via Creator (constructor or static factory method). It is not a full-featured implementation in that its set method should usually not be called for primary mutation -- instead, value must separately passed -- but some aspects are still needed (specifically, injection).Note on injectable values: unlike with other mutators, where deserializer and injecting are separate, here we treat the two as related things. This is necessary to add proper priority, as well as to simplify coordination.

_annotated
protected final AnnotatedParameter _annotated
Placeholder that represents constructor parameter, when it is created from actual constructor. May be null when a synthetic instance is created.
-
_injectableValueId
protected final Object _injectableValueId
Id of value to inject, if value injection should be used for this parameter (in addition to, or instead of, regular deserialization).

_fallbackSetter
protected SettableBeanProperty _fallbackSetter
In special cases, when implementing "updateValue", we cannot use constructors or factory methods, but have to fall back on using a setter (or mutable field property). If so, this refers to that fallback accessor.Mutable only to allow setting after construction, but must be strictly set before any use.

_ignorable

Marker flag that may have to be set during construction, to indicate that although property may have been constructed and added as a placeholder, it represents something that should be ignored during deserialization. This mostly concerns Creator properties which may not be easily deleted during processing.- Since:
