NAME

       SoMFEngine -

       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

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

       Reimplemented from SoMField.

   virtual 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.

   virtual 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.

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

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

   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 (int start, int numarg = -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 (int start, int numarg) [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.
