fetchBranch

ModelFilterTreesContextReadOnly.FilterTreeNode fetchBranch(long leafId)

Fetch one branch of the tree, starting from the given node up to the root.

Can be walked up via the parent of the nodes and down via the (unique) child of the nodes.

For example, given the following tree:

• root (id=1)
  • a (id=2)
    • c (id=4)
    • d (id=5)
  • b (id=3)
    • e (id=6)
    • f (id=7)

tree.fetchBranch(5) will fetch:

• root (id=1)
  • a (id=2)
    • d (id=5)

and return node d

tree.fetchBranch(3) will fetch:

• root (id=1)
  • b (id=3)

and return node b

Parameters:

leafId - the id of the starting node for the branch

Returns:

the leaf of the fetched branch
