        Description copied from class: AbstractSchema
        Decode a byteBuf into an object using the schema definition and deserializer implementation

        Do not modify reader/writer index of ByteBuf so, it can be reused to access correct data.

        Specified by:
        decode in class AbstractSchema<java.lang.String>
        Parameters:
        byteBuf - the byte buffer to decode
        Returns:
        the deserialized object
