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. See also SoEngine, SoSFEngine Member Function Documentation void * SoMFEngine::createInstance (void ) [static] This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. Creates a new instance of the class type corresponding to the SoType object. SoType SoMFEngine::getClassTypeId (void ) [static] This static method returns the SoType object associated with objects of this class. SoType SoMFEngine::getTypeId (void ) const [virtual] Returns the type identification of an object derived from a class inheriting SoField. This is used for runtime type checking and "downward" casting. 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. virtual void SoMFEngine::deleteAllValues (void ) [protected], [virtual] Implements SoMField. virtual void SoMFEngine::copyValue (int to, int from) [protected], [virtual] Implements SoMField. const SoEngine ** SoMFEngine::getValues (const int start) const [inline] Returns a pointer to the values array. void SoMFEngine::initClass (void ) [static] Internal method called upon initialization of the library (from SoDB::init()) to set up the type system. void SoMFEngine::fixCopy (SbBool copyconnections) [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 as well. 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. Author Generated automatically by Doxygen for Coin from the source code.
