DESCRIPTION
This field maintains a set of pointers to SoNode instances, correctly
maintaining their reference counts.
SoMFNodes are written to file as one or more nodes. When more than one
value is present, all of the values are enclosed in square brackets and
separated by commas; for example:
[ Cube { }, Sphere { radius 2.0 }, USE myTranslation ]
FUNCTIONS
SoType SoMNodeGetClassTypeId()
void SoMNodeGetTypeId(const SoMNode *this)
Returns the type for this class or a particular object of this
class.
SoNode * SoMNodeGet(const SoMNode *this, int i)
Returns the i'th value of the field. Indexing past the end of the
field (passing in i greater than getNum()) will return garbage.
const SoNode * * SoMNodeGetN(const SoMNode *this, int start)
Returns a pointer into the array of values in the field, starting at
index start. The values are read-only; see the
startEditing()/finishEditing() methods for a way of modifying values
in place.
int SoMNodeFind(SoMNode *this, SoNode * targetValue,
SbBool addIfNotFound = FALSE)
Finds the given value in the array and returns the index of that
value in the array. If the value is not found, -1 is returned. If
addIfNotFound is set, then targetValue is added to the end of the
array (but -1 is still returned).
Page 2SoMFNode(3IV)
void SoMNodeSetN(SoMNode *this, int start, int num, const
SoNode * *newValues)
Sets num values starting at index start to the values in newValues.
The array will be automatically be made larger to accomodate the new
values, if necessary.
void SoMNodeSet1(SoMNode *this, int index, SoNode *
newValue)
Sets the index'th value in the array to newValue. The array will be
automatically expanded, if necessary.
void SoMNodeSet(SoMNode *this, SoNode * newValue)
Sets the first value in the array to newValue, and deletes the
second and subsequent values.
int SoMNodeIsEq(const SoMNode *this, const SoMFNode *f)
int SoMNodeIsNEq(const SoMNode *this, const SoMFNode *f)
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).
SoNode * * SoMNodeStartEdit(SoMNode *this)
void SoMNodeFinishEdit(SoMNode *this)
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 StartEdit() and FinishEdit() (e.g. Set1(),
Set(), etc).
Fields, engines or sensors connected to this field and sensors are
not notified that this field has changed until FinishEdit() is
called. Calling FinishEdit() always sets the IsDflt flag to FALSE
and informs engines and sensors that the field changed, even if none
of the values actually were changed.
