setString method

int setString(String value, BufferEncoding encoding, [ int offset = 0, int? length, ])

Writes an `encoded value to a region of the buffer.

Returns the position of the last element written to the buffer (offset + decoded-length).

The encoded value is written to the range [offset : offset+length]. If length is omitted, the range extends to the end of the buffer.

The range must satisfy the relations 0 ≤ offset ≤ offset+length ≤ this.length.

Implementation

int setString(
  final String value,
  final BufferEncoding encoding, [
  final int offset = 0,
  final int? length,
]) {
  final Iterable<int> bytes = _decode(value, encoding);
  final int rngLength = length ?? min(this.length - offset, bytes.length);
  _data.setRange(offset, offset + rngLength, bytes);
  return offset + rngLength;
}
