read method

@override CommitOp? read(BinaryReader reader)

Is called when a value has to be decoded.

Implementation

@override
CommitOp? read(BinaryReader reader) {
  var numOfFields = reader.readByte();
  var fields = <int, dynamic>{
    for (var i = 0; i < numOfFields; i++) reader.readByte(): reader.read()
  };
  CommitOp? commitOp;
  switch (fields[0]) {
    case '-':
      commitOp = CommitOp.DELETE;
      break;
    case '+':
      commitOp = CommitOp.UPDATE;
      break;
    case '#':
      commitOp = CommitOp.UPDATE_META;
      break;
    case '*':
      commitOp = CommitOp.UPDATE_ALL;
      break;
  }
  return commitOp;
}
