KeyDispatchCodec

protected KeyDispatchCodec(String typeKey,
                           Codec<K> keyCodec,
                           (? super V) -> ? extends DataResult<? extends K> type,

KeyDispatchCodec

public KeyDispatchCodec(String typeKey,
                        Codec<K> keyCodec,
                        (? super V) -> ? extends DataResult<? extends K> type,
                        (? super K) -> ? extends DataResult<? extends Codec<? extends V>> codec)

Assumes codec(type(V)) is Codec<V>

Method Detail

unsafe

public static <K,V> KeyDispatchCodec<K,V> unsafe(String typeKey,
                                                 Codec<K> keyCodec,

                                                 (? super V) -> ? extends DataResult<? extends Encoder<V>> encoder)

Will assume that the result of all elements is a map

decode

public <T> DataResult<V> decode(DynamicOps<T> ops,
                                MapLike<T> input)

Description copied from interface: MapDecoder

Decodes an object from the given map of serialized entries. If decoding fails (for example, if a key is absent or has an incompatible value), returns an error DataResult.

Type Parameters:

T - The type of the serialized form.

Parameters:

ops - The DynamicOps instance defining the serialized form.

input - A map or maplike object containing the serialized entries.

Returns:

A DataResult containing the decoded object, or an error if no object could be decoded.

See Also:

MapDecoder.compressedDecode(DynamicOps, Object)

encode

public <T> RecordBuilder<T> encode(V input,
                                   DynamicOps<T> ops,
                                   RecordBuilder<T> prefix)

Description copied from interface: MapEncoder

Encodes the input into a set of record fields that are added to the given builder. If a record field cannot be serialized, it is not added to the builder.

Type Parameters:

T - The type of the serialized form.

Parameters:

input - The value to serialize.

ops - The DynamicOps instance defining the serialized form.

prefix - A RecordBuilder to add the serialized fields to.

Returns:

The builder, with the serialized fields added.

keys

public <T> Stream<T> keys(DynamicOps<T> ops)

Description copied from interface: Keyable

Returns the set of keys this object defines or accepts, serialized to the provided form.

Specified by:

keys in interface Keyable

Specified by:

keys in class MapCodec<V>

Type Parameters:

T - The type of the serialized form.

Parameters:

ops - The DynamicOps instance defining the serialized form.

Returns:

The set of keys this object defines.

toString

public String toString()

Overrides:

toString in class Object
