65 A multiple-value field that contains any number of floating point val‐
66 ues.
67 SoMFFloats are written to file as one or more values in standard scien‐
69 tific notation. When more than one value is present, all of the values
70 are enclosed in square brackets and separated by commas; for example:
71 [ 1.0, 2.3, 5, 6.2e4, -100, ]
73 The last comma is optional.
75
77 static SoType getClassTypeId()
78 virtual void getTypeId() const
79 Returns the type for this class or a particular object of this
80 class.
81 float operator [](int i) const
83 Returns the i'th value of the field. Indexing past the end of the
84 field (passing in i greater than getNum()) will return garbage.
85 const float * getValues(int start) const
87 Returns a pointer into the array of values in the field, starting at
88 index start. The values are read-only; see the startEditing()/fin‐
89 ishEditing() methods for a way of modifying values in place.
90 int find(float targetValue, SbBool addIfNotFound = FALSE)
92 Finds the given value in the array and returns the index of that
93 value in the array. If the value is not found, -1 is returned. If
94 addIfNotFound is set, then targetValue is added to the end of the
95 array (but -1 is still returned).
96 void setValues(int start, int num, const float *newValues)
98 Sets num values starting at index start to the values in newValues.
99 The array will be automatically be made larger to accomodate the new
100 values, if necessary.
101 void set1Value(int index, float newValue)
103 Sets the index'th value in the array to newValue. The array will be
104 automatically expanded, if necessary.
105 float operator =(float newValue)
107 void setValue(float newValue)
108 Sets the first value in the array to newValue, and deletes the sec‐
109 ond and subsequent values.
110 int operator ==(const SoMFFloat &f) const
112 int operator !=(const SoMFFloat &f) const
113 Returns TRUE if all of the values of this field equal (do not equal)
114 those of the given field. If the fields are different types FALSE
115 will always be returned (even if one field is an SoMFFloat with one
116 value of 1.0 and the other is an SoMFInt with a value of 1, for
117 example).
118 float * startEditing()
120 void finishEditing()
121 startEditing() returns a pointer to the internally-maintained array
122 that can be modified. The values in the array may be changed, but
123 values cannot be added or removed. It is illegal to call any other
124 editing methods between startEditing() and finishEditing() (e.g.
125 set1Value(), setValue(), etc).
126 Fields, engines or sensors connected to this field and sensors are
128 not notified that this field has changed until finishEditing() is
129 called. Calling finishEditing() always sets the isDefault() flag to
130 FALSE and informs engines and sensors that the field changed, even
131 if none of the values actually were changed.
