Method Detail

getSource

public Node getSource()

Description copied from interface: Relation

Retrieves the source of the relation

Specified by:

getSource in interface Relation

Following copied from interface: org.mmbase.bridge.Relation

Returns:

the source node

getDestination

public Node getDestination()

Description copied from interface: Relation

Retrieves the destination of the relation

Specified by:

getDestination in interface Relation

Following copied from interface: org.mmbase.bridge.Relation

Returns:

the destination node

setSource

public void setSource(Node node)

Description copied from interface: Relation

set the source of the relation

Specified by:

setSource in interface Relation

Following copied from interface: org.mmbase.bridge.Relation

Parameters:

the - source node

setDestination

public void setDestination(Node node)

Description copied from interface: Relation

set the destination of the relation

Specified by:

setDestination in interface Relation

Following copied from interface: org.mmbase.bridge.Relation

Parameters:

the - destination node

getRelationManager

public RelationManager getRelationManager()

Description copied from interface: Relation

Retrieves the RelationManager used

Specified by:

getRelationManager in interface Relation

Following copied from interface: org.mmbase.bridge.Relation

Returns:

the RelationManager

commit

public void commit()

Description copied from interface: Node

Commit the node to the database. Makes this node and/or the changes made to this node visible to the cloud. If this method is called for the first time on this node it will make this node visible to the cloud, otherwise the modifications made to this node using the set methods will be made visible to the cloud. This action fails if the current node is not in edit mode. If the node is in a transaction, nothing happens - actual committing occurs through the transaction.

Specified by:

commit in interface Node

Overrides:

commit in class BasicNode

equals

public boolean equals(java.lang.Object o)

Compares two relations, and returns true if they are equal. This effectively means that both objects are relations, and they both refer to the same objectnode

Overrides:

equals in class BasicNode

Parameters:

o - the object to compare it with

hashCode

public int hashCode()

Returns the object's hashCode. This effectively returns th objectnode's number

Overrides:

hashCode in class BasicNode
