Detailed Description
template<typename T>
class octomap::OcTreeDataNode< T >
Basic node in the OcTree that can hold arbitrary data of type T in value. This is the base class for nodes used in an OcTree. The used implementation for occupancy mapping is in OcTreeNode.#
- Template Parameters:
-
T data to be stored in the node (e.g. a float for probabilities)

Member Function Documentation
| void octomap::OcTreeDataNode< T >::allocChildren | ( | ) | [protected] |
| bool octomap::OcTreeDataNode< T >::childExists | ( | unsigned int | i | ) | const |
Safe test to check of the i-th child exists, first tests if there are any children.
- Returns:
- true if the i-th child exists
| bool octomap::OcTreeDataNode< T >::collapsible | ( | ) | const |
A node is collapsible if all children exist, don't have children of their own and have the same occupancy value
| bool octomap::OcTreeDataNode< T >::createChild | ( | unsigned int | i | ) |
initialize i-th child, allocate children array if needed
Reimplemented in octomap::ColorOcTreeNode, octomap::OcTreeNodeStamped, octomap::CountingOcTreeNode, and octomap::OcTreeNode.
| void octomap::OcTreeDataNode< T >::deleteChild | ( | unsigned int | i | ) |
Deletes the i-th child of the node.
| void octomap::OcTreeDataNode< T >::expandNode | ( | ) |
Expands a node (reverse of pruning): All children are created and their occupancy probability is set to the node's value.
You need to verify that this is indeed a pruned node (i.e. not a leaf at the lowest level)
Reimplemented in octomap::ColorOcTreeNode, and octomap::CountingOcTreeNode.
| OcTreeDataNode<T>* octomap::OcTreeDataNode< T >::getChild | ( | unsigned int | i | ) |
- Returns:
- a pointer to the i-th child of the node. The child needs to exist.
Reimplemented in octomap::ColorOcTreeNode, octomap::CountingOcTreeNode, octomap::OcTreeNode, and octomap::OcTreeNodeStamped.
| const OcTreeDataNode<T>* octomap::OcTreeDataNode< T >::getChild | ( | unsigned int | i | ) | const |
- Returns:
- a const pointer to the i-th child of the node. The child needs to exist.
Reimplemented in octomap::ColorOcTreeNode, octomap::CountingOcTreeNode, octomap::OcTreeNode, and octomap::OcTreeNodeStamped.
| T octomap::OcTreeDataNode< T >::getValue | ( | ) | const [inline] |
- Returns:
- value stored in the node
Definition at line 118 of file OcTreeDataNode.h.
| bool octomap::OcTreeDataNode< T >::hasChildren | ( | ) | const |
- Returns:
- true if the node has at least one child
| bool octomap::OcTreeDataNode< T >::operator== | ( | const OcTreeDataNode< T > & | rhs | ) | const |
Equals operator, compares if the stored value is identical.
| bool octomap::OcTreeDataNode< T >::pruneNode | ( | ) |
Prunes a node when it is collapsible
- Returns:
- true if pruning was successful
Reimplemented in octomap::ColorOcTreeNode.
| std::istream& octomap::OcTreeDataNode< T >::readValue | ( | std::istream & | s | ) |
Read node from binary stream (incl. float value), recursively continue with all children.
- Parameters:
-
s
- Returns:
Reimplemented in octomap::ColorOcTreeNode.
| void octomap::OcTreeDataNode< T >::setValue | ( | T | v | ) | [inline] |
sets value to be stored in the node
Definition at line 120 of file OcTreeDataNode.h.
| std::ostream& octomap::OcTreeDataNode< T >::writeValue | ( | std::ostream & | s | ) | const |
Write node to binary stream (incl float value), recursively continue with all children. This preserves the complete state of the node.
- Parameters:
-
s
- Returns:
Reimplemented in octomap::ColorOcTreeNode.
