Constructor & Destructor Documentation

openvrml::mfdouble::mfdouble ( std::vector< double >::size_type  n = 0,
double  value = 0.0f 
) throw ( std::bad_alloc ) [explicit]

Construct.

Creates an mfdouble with n copies of value.

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

openvrml::mfdouble::mfdouble ( 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::mfdouble::mfdouble ( const mfdouble mfd  ) 

Construct a copy.

Parameters:
[in] mfd the instance to copy.

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

Destroy.

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


Member Function Documentation

openvrml::mfdouble & openvrml::mfdouble::operator= ( const mfdouble mfd  )  throw ( std::bad_alloc )

Assign.

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

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

Access.

Returns:
the double-precision values.

Reimplemented from openvrml::field_value.

void openvrml::mfdouble::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::mfdouble::swap ( mfdouble mfd  )  throw ()

Swap.

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

std::auto_ptr< openvrml::field_value > openvrml::mfdouble::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::mfdouble & openvrml::mfdouble::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 mfdouble object.
std::bad_alloc if memory allocation fails.

Implements openvrml::field_value.

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

Get the type identifier for the class.

Returns:
field_value::mfdouble_id.

Implements openvrml::field_value.

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

Print to an output stream.

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

Implements openvrml::field_value.


Friends And Related Function Documentation

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

Compare for equality.

Parameters:
[in] lhs left-hand operand.
[in] rhs right-hand operand.
Returns:
true if lhs and rhs have the same value; false otherwise.

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

Compare for inequality.

Parameters:
[in] lhs left-hand operand.
[in] rhs right-hand operand.
Returns:
true if lhs and rhs do not have the same value; false otherwise.

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

Swap the values of a and b.

Does not throw.

Parameters:
[in,out] a 
[in,out] b
