Methods
None
MFInt32 Object
The MFInt32 object corresponds to an X3D MFInt32 field. It is used to store a onedimensional array of SFInt32 objects. Individual elements of the array can be referenced using the standard Cstyle dereferencing operator (e.g. mfInt32ObjectName[index], where index is an integervalued expression with 0<=index<length and length is the number of elements in the array). Assigning to an element with index > length results in the array being dynamically expanded to contain length elements. All elements not explicitly initialized are set to 0.
Instance Creation Method(s)
mfInt32ObjectName = new MFInt32 ([number, number, …])
The creation method can be passed 0 or more integervalued expressions to initialize the elements of the array.
