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() {
  // A length-prefixed codec always has at least the compact-encoded length prefix,
  // even if the inner codec produces zero bytes (length 0 = 0x00, which is 1 byte)
  return false;
}
