## Detailed Description

Abstract base class for normal nodes.

## Constructor & Destructor Documentation

openvrml::navigation_info_node::~navigation_info_node | ( |  | ) | throw ()`[pure virtual]`

Destroy.

openvrml::navigation_info_node::navigation_info_node | ( | const node_type & | t,
|  | const boost::shared_ptr< openvrml::scope > & | scope |
| ) |  |  | throw ()`[protected]`

Construct.

Parameters:

  `[in]` | t | the `node_type` associated with the node.
  `[in]` | scope | the `scope` the node belongs to.

## Member Function Documentation
