The following function gives out the error "no return at the end of function".
Such is not necessary because the end brecket "}" is unreachable.

private final class TreeNode
{
private TreeNode lChild, rChild, bNeigh, lNeigh, rNeigh;
public TreeNode getNode(tNode request)
{
switch (request)
{
case tNode.lChild: return lChild;
case tNode.rChild: return rChild;
case tNode.bNeigh: return bNeigh;
case tNode.lNeigh: return lNeigh;
case tNode.rNeigh: return rNeigh;
default: assert(false, "Requested inexistent node");
}
}
