Constructor Details

DispatchCodec

public DispatchCodec(String typeKey,
 Codec<K> keyCodec,
 Function<? super V,? extends K> typeGetter,
 Function<? super K,? extends Codec<? extends V>> codecGetter)

Creates a dispatch codec.

Parameters:

typeKey - Name of the discriminator field.

keyCodec - Codec used for discriminator values.

typeGetter - Extracts the discriminator from a value.

codecGetter - Resolves a codec from a discriminator value.

Method Details

decode

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

Description copied from interface: Codec

Decodes a serialized input of a specific data format into a Java object.

Specified by:

decode in interface Codec<K>

Type Parameters:

D - The type of the serialized data.

Parameters:

ops - The provider defining how to navigate and read data of type D.

input - The raw serialized input to be processed.

Returns:

A DataResult containing the decoded object or an error state.

encode

public <D> DataResult<D> encode(DynamicOps<D> ops,
 V value)

Description copied from interface: Codec

Encodes a Java object into its serialized representation.

Specified by:

encode in interface Codec<K>

Type Parameters:

D - The target type of the serialized data.

Parameters:

ops - The provider defining how to construct data of type D.

value - The Java object instance to be serialized.

Returns:

A DataResult containing the serialized data or an error state.

describe

public String describe()

Description copied from interface: Codec

Outputs a structural description of the expected format for this codec. Useful for schema generation and validation debugging.

Specified by:

describe in interface Codec<K>

Returns:

The schema definition representing the target type.

accept

public <R> R accept(CodecVisitor<R> visitor)

Description copied from interface: Codec

Routes this instance into the visitor API to construct contextual schema layouts.

Specified by:

accept in interface Codec<K>

Type Parameters:

R - The layout target natively returning explicitly mapped variants.

Parameters:

visitor - The evaluation logic instance.

Returns:

Evaluated variant functionally extracting outputs.
