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() {
  return StrCodec.codec.isSizeZero() &&
      StorageEntryModifier.codec.isSizeZero() &&
      StorageEntryType.codec.isSizeZero() &&
      U8SequenceCodec.codec.isSizeZero() &&
      SequenceCodec(StrCodec.codec).isSizeZero();
}
