DESCRIPTION
A multiple-value field that contains any number of enumerated type values, stored as ints. Nodes that use this field class define mnemonic names for values. These names should be used when setting or testing the values of the field, even though the values are treated as integers in the methods.

SoMFEnums are written to file as a set of mnemonic enumerated type names. These names differ among uses of this field in various node classes. See the reference pages for specific nodes for the names.

When more than one value is present, all of the values are enclosed in square brackets and separated by commas.

METHODS
void
setValue(const SbName &name)
Sets this field to contain one and only one value, which is the mnemonic name as a string.

void
set1Value(int index, const SbName &name)
Sets the index'th value to be the integer corresponding to the mnemonic name in the given string.

static SoType
getClassTypeId()
virtual void
getTypeId() const
Returns the type for this class or a particular object of this class.

int
operator [](int i) const
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 int *
getValues(int start) const
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
find(int 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).

void
setValues(int start, int num, const int *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
set1Value(int index, int newValue)
Sets the index'th value in the array to newValue. The array will be automatically expanded, if necessary.

int
operator =(int newValue)
void
setValue(int newValue)
Sets the first value in the array to newValue, and deletes the second and subsequent values.

int
operator ==(const SoMFEnum &f) const
int
operator !=(const SoMFEnum &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).

int *
startEditing()
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.
