This field maintains a set of pointers to SoEngine instances, correctly maintaining their reference counts.

SoMFEngines are written to file as one or more engines. When more than one value is present, all of the values are enclosed in square brackets and separated by commas; for example:

[ ElapsedTime { }, OneShot { duration 2.0 }, USE myCalculator ]

int operator !=(const SoMFEngine &f) const

Returns TRUE if all of the values of this field equal (do not equal) those of the given field. If the fields are different types FALSE will always be returned (even if one field is an SoMFFloat with one value of 1.0 and the other is an SoMFInt with a value of 1, for example).

void finishEditing()

startEditing() returns a pointer to the internally-maintained array that can be modified. The values in the array may be changed, but values cannot be added or removed. It is illegal to call any other editing methods between startEditing() and finishEditing() (e.g. set1Value(), setValue(), etc).

Fields, engines or sensors connected to this field and sensors are not notified that this field has changed until finishEditing() is called. Calling finishEditing() always sets the isDefault() flag to FALSE and informs engines and sensors that the field changed, even if none of the values actually were changed.
