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.
