DESCRIPTION

A multiple-value field that contains any number of floating point values.

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



[ 1.0, 2.3, 5, 6.2e4, -100, ]

The last comma is optional.

METHODS

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

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

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

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

    float *    
                    
float *              startEditing()    
void    
                    
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.
