isSizeZero method

@override bool isSizeZero()

Is Size Zero

Iterate through the inner codecs if available, and find whether any of it is non-zero size or not.

Helps to avoid encoding or decoding the values who encapsulates the empty Composite Codec inside one another.

Implementation

@override
bool isSizeZero() {
  // BitSequence always has a length prefix (compact-encoded), so it can never be size zero
  return false;
}
