Int32x4List class

A fixed-length list of Int32x4 numbers that is viewable as a TypedData.

For long lists, this implementation will be considerably more space- and time-efficient than the default List implementation.

Constructors

Int32x4List(int length)
factory
Creates a Int32x4List of the specified length (in elements), all of whose elements are initially zero.
Int32x4List.fromList(List<Int32x4> elements)
factory
Creates a Int32x4List with the same length as the elements list and copies over the elements.
Int32x4List.sublistView(TypedData data, [int start = 0, int? end])
factory
Creates an Int32x4List view on a range of elements of data.
Int32x4List.view(ByteBuffer buffer, [int offsetInBytes = 0, int? length])
factory
Creates a Int32x4List view of the specified region in buffer.
