Member Function Documentation

FieldValue & assign (  const FieldValue &    value )  throw (std::bad_cast) [virtual]

Virtual assignment. Parameters: value  the new value to give the object. Returns: a reference to the object. Exceptions: std::bad_cast  if value is not an SFNode. Implements FieldValue.

std::auto_ptr< FieldValue > 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 FieldValue.

const NodePtr & get (    )  const throw ()

Get value. Returns: a smart pointer to this object's Node

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

Print to an output stream. Parameters: out  an output stream. Implements FieldValue.

void set (  const NodePtr &    node )  throw ()

Set value. Parameters: node  a smart pointer to a Node, or to 0 if setting this SFNode to NULL.

FieldValue::Type type (    )  const throw () [virtual]

Get the FieldValue::Type associated with this class. Returns: FieldValue::sfnode. Implements FieldValue.
