Uint8ClampedList.view constructor
Creates a Uint8ClampedList view of the specified region in the
specified byte buffer
.
Changes in the Uint8List will be visible in the byte buffer
and vice versa.
If the offsetInBytes
index of the region is not specified,
it defaults to zero (the first byte in the byte buffer).
If the length is not specified, it defaults to null
,
which indicates that the view extends to the end of the byte buffer.
Throws RangeError if offsetInBytes
or length
are negative, or
if offsetInBytes
+ (length
* elementSizeInBytes) is greater than
the length of buffer
.
Note that when creating a view from a TypedData list or byte data,
that list or byte data may itself be a view on a larger buffer
with a TypedData.offsetInBytes greater than zero.
Merely doing Uint8ClampedList.view(other.buffer, 0, count)
may not
point to the bytes you intended. Instead you may need to do:
Uint8ClampedList.view(other.buffer, other.offsetInBytes, count)
Alternatively, use Uint8ClampedList.sublistView which includes this computation.
Uint8ClampedList.sublistView(other, 0, count)
(The third argument is an end index rather than a length, so if you start from a position greater than zero, you need not reduce the count correspondingly).
Implementation
factory Uint8ClampedList.view(ByteBuffer buffer,
[int offsetInBytes = 0, int length]) {
return buffer.asUint8ClampedList(offsetInBytes, length);
}
