Detailed DescriptionThe SoSFEngine class is a container for a single engine​. This field container stores a pointer to a Coin engine​. It takes care of the necessary functionality for handling copy, import and export operations​. Note that the engine pointer stored in a field instance of this type may be a NULL pointer​. See also SoEngine, SoMFEngine

---

Member Function Documentation

---

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

---

void SoSFEngine::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 SoSFEngine::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​.
