getDnDPathToNode

public static int[] getDnDPathToNode(SQLObject node,
                                     SQLObject treeRoot)

Creates an integer array which holds the child indices of each node starting from the root which lead to node "node."

This has the distinct disadvantage of complete lack of context. If you drag an item from one dbtree to another playpen, the playpen can't tell that the drop came from a different object tree, and it will do the lookup based on the same set of offsets in its own tree. Sometimes it will be a valid path (but to the wrong item) and sometimes it will be an invalid path (because one of the steps is out of range). Either way, you get the wrong answer.

Parameters:

node - The SQLObject you want the path to

getNodeForDnDPath

public static SQLObject getNodeForDnDPath(SQLObject root,
                                          int[] path)
                                   throws ArchitectException

Throws:

ArchitectException

toString
