getPathToRoot

public Object[] getPathToRoot(T aNode)

Builds the parents of node up to and including the root node, where the original node is the last element in the returned array. The length of the returned array gives the node's depth in the tree.

Parameters:

aNode - the TreeNode to get the path for

getPathToRoot

protected Object[] getPathToRoot(T aNode,
 int depth)

Builds the parents of node up to and including the root node, where the original node is the last element in the returned array. The length of the returned array gives the node's depth in the tree.

Parameters:

aNode - the TreeNode to get the path for

depth - an int giving the number of steps already taken towards the root (on recursive calls), used to size the returned array

Returns:

an array of TreeNodes giving the path from the root to the specified node
