Virtual copy constructor.

Returns:
a pointer to a copy of the object.
Exceptions:
std::bad_alloc if memory allocation fails.

Implements openvrml::field_value.

field_value & openvrml::sfnode::assign const field_value value  )  throw (std::bad_cast) [virtual]
 

Virtual assignment.

Parameters:
value the new value to give the object.
Returns:
a reference to the object.
Exceptions:
std::bad_cast if value is not an sfnode.

Implements openvrml::field_value.

Get the field_value::type_id associated with this class.

Returns:
field_value::sfnode.

Implements openvrml::field_value.

void openvrml::sfnode::print std::ostream &  out  )  const [private, virtual]
 

Print to an output stream.

Parameters:
out an output stream.

Implements openvrml::field_value.
