Field Detail

_from
protected transient java.lang.Object _from
-
_fieldName
protected java.lang.String _fieldName
Name of field (for beans) or key (for Maps) that is part of the reference. May be null for Collection types (which generally have_index
defined), or when resolving Map classes without (yet) having an instance to operate on.
-
_index
protected int _index
Index within aCollection
instance that contained the reference; used if index is relevant and available. If either not applicable, or not available, -1 is used to denote "not known" (or not relevant).
-
_desc
protected java.lang.String _desc
Lazily-constructed description of this instance; needed mostly to allow JDK serialization to work in case where_from
is non-serializable (and has to be dropped) but we still want to pass actual description along.- Since:

Method Detail

getFrom
public java.lang.Object getFrom()
Object through which reference was resolved. Can be either actual instance (usually the case for serialization), or Class (usually the case for deserialization).Note that this value must be `transient` to allow serializability (as often such Object is NOT serializable; or, in case of `Class`, may not available at the point of deserialization). As such will return `null` if instance has been passed using JDK serialization.
