Field Detail

_from

protected java.lang.Object _from

Object through which reference was resolved. Can be either actual instance (usually the case for serialization), or Class (usually the case for deserialization).

_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 a Collection 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".
