72 A multiple-value field that contains any number of two-dimensional vec‐
73 tors.
74 SoMFVec2fs are written to file as one or more pairs of floating point
76 values separated by whitespace. When more than one value is present,
77 all of the values are enclosed in square brackets and separated by com‐
78 mas; for example:
79 [ 0 0, 1.2 3.4, 98.6 -4e1 ]
81
85 void setValues(int start, int num, const float xy[][2])
86 Sets num values starting at index start to the given floating point
87 values. There must be num*2 values in the passed array.
88 void set1Value(int index, float x, float y)
90 void set1Value(int index, const float xy[2])
91 Set the index'th value to the given floating point values.
92 void setValue(float x, float y)
94 void setValue(const float xy[2])
95 Sets the field to contain the given value and only the given value
96 (if the array had multiple values before, they are deleted).
97 static SoType getClassTypeId()
99 virtual void getTypeId() const
100 Returns the type for this class or a particular object of this
101 class.
102 const SbVec2f & operator [](int i) const
104 Returns the i'th value of the field. Indexing past the end of the
105 field (passing in i greater than getNum()) will return garbage.
106 const SbVec2f * getValues(int start) const
108 Returns a pointer into the array of values in the field, starting at
109 index start. The values are read-only; see the startEditing()/fin‐
110 ishEditing() methods for a way of modifying values in place.
111 int find(const SbVec2f & targetValue, SbBool addIfNot‐
113 Found = FALSE)
114 Finds the given value in the array and returns the index of that
115 value in the array. If the value is not found, -1 is returned. If
116 addIfNotFound is set, then targetValue is added to the end of the
117 array (but -1 is still returned).
118 void setValues(int start, int num, const SbVec2f *newVal‐
120 ues)
121 Sets num values starting at index start to the values in newValues.
122 The array will be automatically be made larger to accomodate the new
123 values, if necessary.
124 void set1Value(int index, const SbVec2f & newValue)
126 Sets the index'th value in the array to newValue. The array will be
127 automatically expanded, if necessary.
128 const SbVec2f & operator =(const SbVec2f & newValue)
130 void setValue(const SbVec2f & newValue)
131 Sets the first value in the array to newValue, and deletes the sec‐
132 ond and subsequent values.
133 int operator ==(const SoMFVec2f &f) const
135 int operator !=(const SoMFVec2f &f) const
136 Returns TRUE if all of the values of this field equal (do not equal)
137 those of the given field. If the fields are different types FALSE
138 will always be returned (even if one field is an SoMFFloat with one
139 value of 1.0 and the other is an SoMFInt with a value of 1, for
140 example).
141 SbVec2f * startEditing()
143 void finishEditing()
144 startEditing() returns a pointer to the internally-maintained array
145 that can be modified. The values in the array may be changed, but
146 values cannot be added or removed. It is illegal to call any other
147 editing methods between startEditing() and finishEditing() (e.g.
148 set1Value(), setValue(), etc).
149 Fields, engines or sensors connected to this field and sensors are
151 not notified that this field has changed until finishEditing() is
152 called. Calling finishEditing() always sets the isDefault() flag to
153 FALSE and informs engines and sensors that the field changed, even
154 if none of the values actually were changed.
