Detailed DescriptionThe 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. See also SoEngine, SoSFEngine

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 int start) const [inline]Returns a pointer to the values array.

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 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.
