       The SoMFEngine class is a container for engines.

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

Detailed Description

       The SoMFEngine class is a container for engines.

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

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

Member Function Documentation

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

       Implements SoField.

   const SoEngine* * SoMFEngine::getValues (const intstart) const [inline]
       \ Returns a pointer to the values array. \

   void SoMFEngine::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 SoMFEngine::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.

   virtual void SoMFEngine::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 SoMFEngine::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.
