Constructor & Destructor Documentation

openvrml::mfvec2f::mfvec2f ( std::vector< vec2f >::size_type  n = 0,
const vec2f value = vec2f() 
) throw (std::bad_alloc) [explicit]

Construct.

Creates an mfvec2f with n copies of value.

Parameters:
n the number elements in mfvec2f::value.
value used to initialize mfvec2f::value.
Exceptions:
std::bad_alloc if memory allocation fails.
Postcondition:
mfvec2f::value.size() is n. Every element in mfvec2f::value is a copy of value.

openvrml::mfvec2f::mfvec2f ( const std::vector< vec2f > &  value  )  throw (std::bad_alloc) [explicit]

Construct.

Parameters:
value initial value.
Exceptions:
std::bad_alloc if memory allocation fails.

template<typename InputIterator>
openvrml::mfvec2f::mfvec2f ( InputIterator  first,
InputIterator  last 
)

Create an mfvec2f with a copy of a range.

Creates an mfvec2f 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::mfvec2f::~mfvec2f (  )  throw () [virtual]

Destroy.

Each of the mfvec2f's value elements is destroyed, and memory allocated for them (if any) is deallocated.


Member Function Documentation

std::auto_ptr< field_value > openvrml::mfvec2f::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.

field_value & openvrml::mfvec2f::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 mfvec2f object.
std::bad_alloc if memory allocation fails.

Implements openvrml::field_value.

field_value::type_id openvrml::mfvec2f::type (  )  const throw () [virtual]

Get the field_value::type_id associated with this class.

Returns:
field_value::mfvec2f_id.

Implements openvrml::field_value.

void openvrml::mfvec2f::print ( std::ostream &  out  )  const [private, virtual]

Print to an output stream.

Parameters:
out an output stream.

Implements openvrml::field_value.

bool operator== ( const mfvec2f lhs,
const mfvec2f 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.

bool operator!= ( const mfvec2f lhs,
const mfvec2f 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.

template<> void swap ( openvrml::mfvec2f a,
openvrml::mfvec2f b 
) [related]

Swap the values of a and b.

Does not throw.

Parameters:
a 
b
