public class BigIntegerDecoder
extends io.netty.handler.codec.ByteToMessageDecoder

Decodes the binary representation of a BigInteger prepended with a magic number ('F' or 0x46) and a 32-bit integer length prefix into a BigInteger instance. For example, { 'F', 0, 0, 0, 1, 42 } will be decoded into new BigInteger("42").
