## Member Function Documentation

void openvrml::time_dependent_node::update | ( | double | time | ) |

Update with the current time.

This function delegates to `do_update`.

Parameters:

  `[in]` | time | the current time.

openvrml::time_dependent_node * openvrml::time_dependent_node::to_time_dependent | ( |  | ) | throw ()`[private, virtual]`

Cast to a `time_dependent_node`.

Returns:
  a pointer to the object.

Reimplemented from openvrml::node.

void openvrml::time_dependent_node::do_update | ( | double | time | ) | `[private, pure virtual]`

Update with the current time.

Parameters:

  `[in]` | time | the current time.
