NAME

       SoSFNode -

       The SoSFNode class is a container for a single node.

       This field container stores a pointer to a Coin node. It takes care of the necessary
       functionality for handling copy, import and export operations.

Detailed Description

       The SoSFNode class is a container for a single node.

       This field container stores a pointer to a Coin node. It takes care of the necessary
       functionality for handling copy, import and export operations.

       Note that the node pointer stored in a field instance of this type may be a NULL pointer.

Member Function Documentation

   SoType SoSFNode::getTypeId (void) const [virtual]
       Returns the type identification instance which uniquely identifies the Coin field class
       the object belongs to.

       See Also:
           getClassTypeId(), SoType

       Implements SoField.

   void SoSFNode::copyFrom (const SoField &f) [virtual]
       Copy value(s) from f into this field. f must be of the same type as this field.

       Implements SoField.

   SbBool SoSFNode::isSame (const SoField &f) const [virtual]
       Check for equal type and value(s).

       Implements SoField.

   void SoSFNode::fixCopy (SbBoolcopyconnections) [virtual]
       This method is internally called after SoField::copyFrom() during scene graph copies, and
       should do the operations necessary for fixing up the field instance after it has gotten a
       new value.

       The default method in the SoField superclass does nothing.

       The application programmer should normally not need to consider this method, unless he
       constructs a complex field type which contains new references to container instances (i.e.
       nodes or engines). Overriding this method is then necessary to update the reference
       pointers, as they could have been duplicated during the copy operation.

       Reimplemented from SoField.

   SbBool SoSFNode::referencesCopy (void) const [virtual]
       Returns TRUE if this field has references to any containers in the scene graph which are
       also duplicated during the copy operation.

       Note that this method only is valid to call during copy operations.

       See also the note about the relevance of the fixCopy() method for application programmers,
       as it is applicable on this method aswell.

       Reimplemented from SoField.
