ACodec encodes and (if supported) decodes data.

Codecs can be fused. For example fusingjson andutf8 producesan encoder that can convert Json objects directly to bytes, or can decodebytes directly to json objects.

Fused codecs generally attempt to optimize the operations and can be fasterthan executing each step of an encoding separately.

TheCodec class provides a default implementation ofencode,decode,fuse andinverted.Subclasses can choose to provide more efficient implementations of these.
