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() {
  // Composite is size zero if it's empty OR if all inner codecs are size zero
  if (mappedCodec.isEmpty) {
    return true;
  }

  return mappedCodec.values.every((codec) => codec.isSizeZero());
}
