class Geo::TreeNode
A generic tree structure, where each node contains an item by value.
Nodes are not copied after construction, but the SetValue function requires that the item type (_Ty) is assignable.
Functions
| Name | Description |
|---|---|
| ~TreeNode() | Destructor. |
| AddChild(const _Ty &) | Add a child node with the given value 'val'. |
| DeleteChild(Geo::s32) | Delete the child with index 'idx', children of the node is assigned to this node at the end of the child array. |
| DeleteSubTree(Geo::s32) | Delete the child with index 'idx' and all nodes below this child. |
| GetChild(Geo::s32) | Get child with index 'idx', NULL if 'idx' is out of range. |
| GetChild(Geo::s32) | Get child with index 'idx', NULL if 'idx' is out of range. |
| GetDepth() | Get the depth of the node. |
| GetLeaves(Geo::GeoArray< const TreeNode< _Ty > * > &) | Fills in an array of all the leaf nodes underneath this node. Returns the total number of leaves in the resulting array. |
| GetLevelFromRoot(Geo::GeoArray< TreeNode< _Ty > * > &, Geo::s32) | Return an array of nodes at the given depth ordered from left to right in the tree. |
| GetLevelFromRoot(Geo::GeoArray< const TreeNode< _Ty > * > &, Geo::s32) | Return an array of nodes at the given depth ordered from left to right in the tree. |
| GetNumChildren() | Number of immediate children nodes. |
| GetNumInternalNodes() | Total number of internal nodes in the tree (i.e. not leaves) |
| GetNumLevels() | Get the number of levels in the tree. |
| GetNumNodes(Geo::s32) | Total number of nodes in a given level. |
| GetNumNodes() | Total number of nodes in the tree. |
| GetParent() | Get the parent node, NULL if this is the root. |
| GetParent() | Get the parent node, NULL if this is the root. |
| GetRoot() | Get the root of the tree. |
| GetRoot() | Get the root of the tree. |
| GetValue() | Get the value stored in the node. |
| GetValue() | Get the value stored in the node. |
| IsLeaf() | Returns whether this is a leaf node, i.e. has no children. |
| IsRoot() | Returns whether this is a root node, i.e. has no parent. |
| Load(Geo::IGeoInputStream &) | Load tree from disk. |
| RemoveChild(Geo::s32) | Remove and return the child with index 'idx' from the tree. |
| Save(Geo::IGeoStream &) | Save tree to disk. |
| SetValue(const _Ty &) | Set the value stored in the node. |
| TreeNode() | Constructor. |
