Method Detail

cloneNodeWithRelations

public static Node cloneNodeWithRelations(Node localNode)

Clone a node with all relations

Parameters:

localNode - the node to be cloned

Returns:

the cloned copy of localNode

cloneNode

public static Node cloneNode(Node localNode)

Clone a node to a cloud, including any fields without keeping administrative information

Parameters:

localNode - the node to clone

Returns:

the newly created node in the other cloud

cloneNodeField

public static void cloneNodeField(Node sourceNode,
                                  Node destinationNode,
                                  Field field)

cloneNodeField copies node fields from one node to the other

Parameters:

sourceNode - the source node

destinationNode - destination node

field - the field to clone

cloneRelation

public static Relation cloneRelation(Node sourceRelation)

Clone relation of the source node to the destination node.

Parameters:

sourceRelation - source relation

Returns:

cloned relation

cloneRelation

public static Relation cloneRelation(Node sourceRelation,
                                     Node sourceNode,
                                     Node destNode)

Clone relation of the source node to the destination node.

Parameters:

sourceRelation - source relation

sourceNode - source node

destNode - destination node

Returns:

cloned relation

cloneRelations

public static void cloneRelations(Node sourceNode,
                                  Node destNode)

Clone relations of the source node to the destination node. In other words, create new relations between the destination node and the nodes which the source node has relations to.

Parameters:

sourceNode - source node

destNode - destination node

cloneRelations

public static void cloneRelations(Node sourceNode,
                                  Node destNode,
                                  String relationName,
                                  String managerName)

Clone relations of the source node to the destination node. In other words, create new relations between the destination node and the nodes which the source node has relations to.

Parameters:

sourceNode - source node

destNode - destination node

relationName - name of relation

managerName - manager of the other nodes which the relations are replicated for.

cloneAliasses

public static void cloneAliasses(Node localNode,
                                 Node destNode)

Clone aliases to the destination node. This only works when the node is in a different cloud

Parameters:

localNode - local node

destNode - destination/remote node

isRelation

protected static boolean isRelation(Node node)

quick test to see if node is a relation by testing fieldnames

Parameters:

node - Possible relation

Returns:

true when relation fields present
