Codec abstract class

A Codec encodes and (if supported) decodes data.

Codecs can be fused. For example fusing JSON and UTF8 produces an encoder that can convert Json objects directly to bytes, or can decode bytes directly to json objects.

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

Properties

decoder → Converter<T, S> read-only: Returns the decoder of this, converting from T to S.
encoder → Converter<S, T> read-only: Returns the encoder from S to T.
inverted → Codec<T, S> read-only: Inverts this.
hashCode → int read-only, inherited: The hash code for this object.
runtimeType → Type read-only, inherited: A representation of the runtime type of the object.

Operators

operator ==(other) → bool inherited: The equality operator.

Methods

decode(T encoded) → S
encode(S input) → T
fuse<R>(Codec<T, R> other) → Codec<S, R>: Fuses this with other.
noSuchMethod(Invocation invocation) → dynamic inherited: Invoked when a non-existent method or property is accessed.
toString() → String inherited: Returns a string representation of this object.
