Detailed Description

A node reference array node field value.


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.

throw() [related]
 

Compare for inequality.

Parameters:
lhs left-hand operand.

Returns:
true if lhs and rhs do not have the same value; false otherwise.

bool operator== const mfnode lhs,

throw() [related]
 

Compare for equality.

Parameters:

Does not throw.

Parameters:
