asByteData method

ByteData asByteData ([int offsetInBytes = 0, int length ])

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

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

The viewed region start at offsetInBytes and contains length bytes. If length is omitted, the range extends to the end of the buffer.

The start index and length must describe a valid range of the buffer:

  • offsetInBytes must not be negative,
  • length must not be negative, and
  • offsetInBytes + length must not be greater than lengthInBytes.

Implementation 

ByteData asByteData([int offsetInBytes = 0, int length]);
