示例1: SplitBranch
nSearchTreeNode BasicSearchTree::SplitBranch(nSearchTreeNode n,size_t depth)
{
if (!n || !m_Nodes[n] || m_Nodes[n]->GetDepth()==depth)
return n;
// for !n it returns the rootnode
// for !m_Nodes[n], it fails by returning n.
// for m_Nodes[n]->GetDepth()==depth, it's a special case (given position is a node)
// so we just return n.
SearchTreeNode* child = m_Nodes[n];
nSearchTreeNode old_parent = child->GetParent();
// Create new node "middle", add it to old_parent in place of child.
// Calculate the parent offset and the new labels' parameters.
size_t parent_offset = depth - child->GetLabelStartDepth();
nSearchTreeLabel labelno = child->GetLabelNo();
unsigned int oldlabelstart = child->GetLabelStart();
unsigned int oldlabellen = child->GetLabelLen();
unsigned int middle_start = oldlabelstart;
unsigned int middle_len = parent_offset;
unsigned int child_start = middle_start + middle_len;
unsigned int child_len = oldlabellen - middle_len;
wxChar middle_char = m_Labels[labelno][middle_start];
wxChar child_char = m_Labels[labelno][child_start];
// Now we're ready to create the middle node and update accordingly
SearchTreeNode* newnode = CreateNode(depth,old_parent,labelno,middle_start,middle_len);
m_Nodes.push_back(newnode);
nSearchTreeNode middle = m_Nodes.size() - 1;
// Add child to middle
child->SetParent(middle);
child->SetLabel(labelno,child_start,child_len);
child->RecalcDepth(this);
newnode->m_Children[child_char]=n;
child->UpdateItems(this);
// Add middle to old_parent
m_Nodes[old_parent]->m_Children[middle_char]=middle;
return middle;
