Constructor & Destructor Documentation

openvrml::mfvec2d::mfvec2d ( std::vector< vec2d >::size_type  n = 0,
const vec2d value = vec2d() 
) throw ( std::bad_alloc ) [explicit]

Construct.

Creates an mfvec2d with n copies of value.

Parameters:
[in] n the number elements in mfvec2d::value.
[in] value used to initialize mfvec2d::value.
Exceptions:
std::bad_alloc if memory allocation fails.
Postcondition:
mfvec2d::value.size() is n. Every element in mfvec2d::value is a copy of value.

openvrml::mfvec2d::mfvec2d ( const value_type value  )  throw ( std::bad_alloc ) [inline, explicit]

Construct.

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

openvrml::mfvec2d::mfvec2d ( const mfvec2d mfv  ) 

Construct a copy.

Parameters:
[in] mfv the instance to copy.

openvrml::mfvec2d::~mfvec2d (  )  throw () [virtual]

Destroy.

Each of the mfvec2d's value elements is destroyed, and memory allocated for them (if any) is deallocated.


Member Function Documentation

openvrml::mfvec2d & openvrml::mfvec2d::operator= ( const mfvec2d mfv  )  throw ( std::bad_alloc )

Assign.

Parameters:
[in] mfv the value to assign.
Returns:
a reference to the instance.
Exceptions:
std::bad_alloc if memory allocation fails.

const openvrml::mfvec2d::value_type & openvrml::mfvec2d::value (  )  const throw ()

Access.

Returns:
the vector values.

Reimplemented from openvrml::field_value.

void openvrml::mfvec2d::value ( const value_type val  )  throw ( std::bad_alloc )

Mutate.

Parameters:
[in] val the new value.
Exceptions:
std::bad_alloc if memory allocation fails.

void openvrml::mfvec2d::swap ( mfvec2d mfv  )  throw ()

Swap.

Parameters:
[in,out] mfv the value to swap with this one.

std::auto_ptr< openvrml::field_value > openvrml::mfvec2d::do_clone (  )  const throw ( std::bad_alloc ) [private, virtual]

Polymorphically construct a copy.

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

Implements openvrml::field_value.

openvrml::mfvec2d & openvrml::mfvec2d::do_assign ( const field_value value  )  throw ( std::bad_cast , std::bad_alloc ) [private, virtual]

Virtual assignment.

Returns:
a reference to the object.
Exceptions:
std::bad_cast if value is not an mfvec2d object.
std::bad_alloc if memory allocation fails.

Implements openvrml::field_value.

openvrml::field_value::type_id openvrml::mfvec2d::do_type (  )  const throw () [private, virtual]

Get the field_value::type_id associated with this class.

Returns:
field_value::mfvec2d_id.

Implements openvrml::field_value.

void openvrml::mfvec2d::print ( std::ostream &  out  )  const [private, virtual]

Print to an output stream.

Parameters:
[in,out] out an output stream.

Implements openvrml::field_value.

Does not throw.

Parameters:
[in,out] a 
[in,out] b
