Method Detail

getNode

public com.ragic.s3.sdb.query.SDBNode getNode(int domainId,
                                              int nodeId)

Returns the node corresponding to the given field ID and node ID.

Parameters:

domainId - field ID of target node.

nodeId - node ID of target node.

Returns:

SDBNode object of interest.

addNode

public int addNode(int domainId,
                   java.lang.String value,
                   boolean mergeSameValue)

Adds a new node or updates a existed node with given value and field ID. When creating a new record in database, root node should be created at first by addNode. Then register other values by updateNode or setFieldValue.

Parameters:

domainId - field to save this new node.

value - value to be saved in this new node.

mergeSameValue - true will not create new node if such value already exists.
false just the opposite.

Returns:

node ID of the new Node

                     int nodeId2)

Create a path between two node. Upon being linked, These two nodes can be accessed from each other by SDBQueryScript objects.

Parameters:

domainId1 - field ID of first node to be linked

nodeId1 - node ID of first node to be linked

domainId2 - field ID of another node to be linked

nodeId2 - node ID of another node to be linked
