Constructor & Destructor Documentation

openvrml::mfnode::mfnode (  std::vector< node_ptr >::size_type  n = 0, const node_ptr &  value = node_ptr() )  throw (std::bad_alloc) [explicit]

Construct. Creates an mfnode with n copies of value. Parameters: n  the number elements in the mfnode. value  used to initialize the mfnode. Exceptions: std::bad_alloc  if memory allocation fails. Postcondition: size is n. Every element is a copy of value.

template<typename InputIterator> openvrml::mfnode::mfnode (  InputIterator  first, InputIterator  last )

Create an mfnode with a copy of a range. Creates an mfnode with a value that is a copy of the range [first, last). Parameters: first  an iterator pointing to the beginning of the range. last  an iterator pointing one past the end of the range.

openvrml::mfnode::~mfnode (   )  throw () [virtual]

Destroy. Each of the mfnode's value elements is destroyed, and memory allocated for them (if any) is deallocated.

Member Function Documentation

field_value & openvrml::mfnode::assign (  const field_value &  value  )  throw (std::bad_cast, std::bad_alloc) [virtual]

Virtual assignment. Returns: a reference to the object. Exceptions: std::bad_cast  if value is not an mfnode object. std::bad_alloc  if memory allocation fails. Implements openvrml::field_value.

std::auto_ptr< field_value > openvrml::mfnode::clone (   )  const throw (std::bad_alloc) [virtual]

Virtual copy constructor. Returns: a pointer to a copy of the object. Exceptions: std::bad_alloc  if memory allocation fails. Implements openvrml::field_value.

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

Print to an output stream. Any null elements in the mfnode will not get printed; VRML97 syntax does not accommodate NULL in an mfnode. Parameters: out  an output stream. Implements openvrml::field_value.

field_value::type_id openvrml::mfnode::type (   )  const throw () [virtual]

Get the field_value::type_id associated with this class. Returns: field_value::mfnode_id. Implements openvrml::field_value.

Friends And Related Function Documentation

bool operator!= (  const mfnode &  lhs, const mfnode &  rhs )  throw() [related]

Compare for inequality. Parameters: lhs  left-hand operand. rhs  right-hand operand. Returns: true if lhs and rhs do not have the same value; false otherwise.

bool operator== (  const mfnode &  lhs, const mfnode &  rhs )  throw() [related]

Compare for equality. Parameters: lhs  left-hand operand. rhs  right-hand operand. Returns: true if lhs and rhs have the same value; false otherwise.

template<> void swap (  openvrml::mfnode &  a, openvrml::mfnode &  b )  [related]

Swap the values of a and b. Does not throw. Parameters: a  b
