$ent->refs()

Syntax

$ent->refs( [$refkindstring [,$entkindstring 
            [, $unique]]] ) 

Description

Returns a list of references. In a scalar context, only the first reference is returned. Each returned reference is an object in the Understand::Ref class.

If the optional argument $refkindstring is not passed, then all references for the entity are returned. Otherwise, $refkindstring should be a language-specific reference filter string. If the optional argument $entkindstring is not passed, then all references to any kind of entity are returned.

Otherwise, $entkindstring should be a language-specific entity filter string that specifies references to what kind of referenced entity are to be returned. See Entity and Reference Kinds for lists of kinds.

If the optional argument $unique is passed with value 1, only the first matching reference to each unique entity is returned.
