X3DArrayField

The X3DArrayField object is the base object of all MF* objects. It is used to store a one-dimensional array of the corresponding SF* objects. Individual elements of the array can be referenced using the standard C-style dereferencing operator (e.g. X3DArrayFieldObjectName[index], where index is an integer-valued 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 0.0.

Instance Creation Method(s)

None

Iterator

The [@@iterator]() method of X3DArrayField instances implements the iterable protocol and allows X3DArrayField objects to be consumed by most syntaxes expecting iterables, such as the spread syntax and for...of loops. It returns a iterator object that yields the elements of the array in order.

const copy = new MFBool (... array); // Copy using spread syntax.

Properties

length

An integer containing the number of elements in the array. Assigning an integer to length changes the number of elements in the array.

Methods

Boolean equals (array)

Returns true if the passed MF* array of the same type is equals to this object, otherwise false.
