asFloat32List method

Float32List asFloat32List ([int offsetInBytes = 0, int length ])

Creates a Float32List view of a region of this byte buffer.

The view is backed by the bytes of this byte buffer. Any changes made to the Float32List will also change the buffer, and vice versa.

The viewed region start at offsetInBytes, which must be 32-bit aligned, and contains length 32-bit integers. If length is omitted, the range extends as far towards the end of the buffer as possible - if lengthInBytes is not divisible by four, the last bytes can't be part of the view.

The start index and length must describe a valid 32-bit aligned range of the buffer:

  • offsetInBytes must not be negative,
  • offsetInBytes must be divisible by four,
  • length must not be negative, and
  • offsetInBytes + length * 4 must not be greater than lengthInBytes.

Implementation

Float32List asFloat32List([int offsetInBytes = 0, int length]) =>
    new UnmodifiableFloat32ListView(
        _data.asFloat32List(offsetInBytes, length));
