Can this EntityIdentifierDescription be treated as a FetchSource and if so does it have any
bidirectional entity references?
|
boolean |

Can this EntityIdentifierDescription be treated as a FetchSource and if so does it have any
fetches?
|
boolean |
isNullable()
Is this fetch nullable?

public EntityReference resolveEntityReference()
FetchSource
EntityReference
, or null if none.
If this object is an EntityReference
, then this object is returned;
otherwise, if this object is a Fetch
, then the nearest
EntityReference
will be resolved from its source, if possible.
If no EntityReference can be resolved, null is return.resolveEntityReference
in interface FetchSource
Fetch.getSource().
