DESCRIPTION
This field maintains a pointer to an SoEngine instance, correctly maintaining its reference count.
SoSFEngines are written to file as the engine they are pointing to. For example:
mySoSFEngineField ElapsedTime {}
is an SoSFEngine field named 'mySoSFEngineField', pointing to an SoElapsedTime engine. If the engine is
used elsewhere, the regular DEF/USE instancing mechanism applies:
anotherSoSFEngineField USE calculator
is an SoSFEngine field that points to a engine named 'calculator' that was DEF'ed earlier in the scene.
METHODS
static SoType getClassTypeId()
virtual void getTypeId() const
Returns the type for this class or a particular object of this class.
SoEngine * getValue() const
Returns this field's value.
SoEngine * operator =(SoEngine * newValue)
void setValue(SoEngine * newValue)
Sets this field to newValue.
int operator ==(const SoSFEngine &f) const
int operator !=(const SoSFEngine &f) const
Returns TRUE if f is of the same type and has the same value as this field.
