Constructor Detail

BasicRelationManager

BasicRelationManager(MMObjectNode node,
                     BasicCloud cloud,
                     int nodeId)

Creates a new Relation manager (for insert). The type of manager (a strictly constrained manager or a role manager) is dependend on the type of the passed node (from either the reldef of typerel builder).

Parameters:

node - the node on which to base the relation manager

cloud - the cloud for which to create the manager

id - the id of the node in the temporary cloud

BasicRelationManager

BasicRelationManager(MMObjectNode node,
                     BasicCloud cloud)

Creates a new instance of Relation manager. The type of manager (a strictly constrained manager or a role manager) is dependend on the type of the passed node (from either the reldef of typerel builder).

Parameters:

node - the node on which to base the relation manager

cloud - the cloud for which to create the manager

Method Detail

isRelationManager

public final boolean isRelationManager()

Specified by:

isRelationManager in interface Node

Overrides:

isRelationManager in class AbstractNode

toRelationManager

public final RelationManager toRelationManager()

Specified by:

toRelationManager in interface Node

Overrides:

toRelationManager in class AbstractNode

initManager

protected void initManager()

Initializes the NodeManager: determines the MMObjectBuilder from the passed node (reldef or typerel), and fills temporary variables to maintain status.

Overrides:

initManager in class BasicNodeManager

setNodeManager

protected void setNodeManager(MMObjectNode node)

Description copied from class: BasicNode

Set nodemanager for node

Overrides:

setNodeManager in class BasicNodeManager

Parameters:

node - node to derive nodemanager from.

getForwardRole

public String getForwardRole()

Specified by:

getForwardRole in interface RelationManager

getReciprocalRole

public String getReciprocalRole()

Specified by:

getReciprocalRole in interface RelationManager

getForwardGUIName

public String getForwardGUIName()

Specified by:

getForwardGUIName in interface RelationManager

getReciprocalGUIName

public String getReciprocalGUIName()

Specified by:

getReciprocalGUIName in interface RelationManager

getDirectionality

public int getDirectionality()

Specified by:

getDirectionality in interface RelationManager

getBuilder

int getBuilder()

getSourceManager

public NodeManager getSourceManager()

Specified by:

getSourceManager in interface RelationManager

getDestinationManager

public NodeManager getDestinationManager()

Specified by:

getDestinationManager in interface RelationManager

createBasicNode

protected final BasicNode createBasicNode()

Description copied from class: BasicNodeManager

BasicNodeManager is garantueed to return BasicNode's. So extendsion must override this, and not BasicNodeManager.createNode()

Overrides:

createBasicNode in class BasicNodeManager

createBasicRelation

protected BasicRelation createBasicRelation()

BasicRelationManager is garantueed to create BasicRelations. Extension therefore most override this and not createBasicNode().

Since:

MMBase-1.8

createRelation

public Relation createRelation(Node sourceNode,
                               Node destinationNode)

Specified by:

createRelation in interface RelationManager

getRelations

public RelationList getRelations(Node node)

Specified by:

getRelations in interface RelationManager

mayCreateRelation

public boolean mayCreateRelation(Node sourceNode,
                                 Node destinationNode)

Specified by:

mayCreateRelation in interface RelationManager

toString

public String toString()

Specified by:

toString in interface Node

Overrides:

toString in class BasicNode
