Constructor Detail

AssociationRef

public AssociationRef(NodeRef sourceRef,
                      QName assocTypeQName,
                      NodeRef targetRef)

Construct a representation of a source --- name ----> target relationship.

Parameters:

sourceRef - the source reference - never null

assocTypeQName - the qualified name of the association type - never null

targetRef - the target node reference - never null.

AssociationRef

public AssociationRef(Long id,

                      QName assocTypeQName,
                      NodeRef targetRef)

Construct a representation of a source --- name ----> target relationship.

Parameters:

id - unique identifier - may be null

sourceRef - the source reference - never null

assocTypeQName - the qualified name of the association type - never null
