Detailed Description

       The SoMFNode class is a container for nodes.

       This field container stores an array of pointers to nodes. It takes care of the necessary
       functionality for handling copy, import and export operations.

       Note that node pointers stored in field instances of this type may be NULL pointers.

Member Function Documentation

   static SoType SoMFNode::getClassTypeId (void) [static] Returns a unique type identifier for
       this field class.
       See also:
           getTypeId(), SoType

       Reimplemented from SoMField.

   virtual SoType SoMFNode::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.

   virtual void SoMFNode::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.

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

   const SoNode* SoMFNode::getValues (const intstart) const [inline]  Returns a pointer to the
       values array.
   void SoMFNode::initClass (void) [static] Internal method called upon initialization of the
       library (from SoDB::init()) to set up the type system.
       Reimplemented from SoMField.

   SbBool SoMFNode::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.

   void SoMFNode::addNode (SoNode *node) Adds a node at the end of the array.

   virtual void SoMFNode::deleteValues (intstart, intnumarg = -1) [virtual] Remove value elements
       from index start up to and including index start + num - 1.
       Elements with indices larger than the last deleted element will be moved downwards in the
       value array.

       If num equals -1, delete from index start and to the end of the array.

       Reimplemented from SoMField.

   virtual void SoMFNode::insertSpace (intstart, intnumarg) [virtual] Insert num 'slots' for new
       value elements from start. The elements already present from start will be moved 'upward'
       in the extended array.
       Reimplemented from SoMField.
