Method Detail

fromCodecs

public static CodecRegistry fromCodecs(Codec<?>... codecs)

Creates a CodecRegistry from the provided list of Codec instances.

This registry can then be used alongside other registries. Typically used when adding extra codecs to existing codecs with the fromRegistries(CodecRegistry...) )} helper.

Parameters:

codecs - the Codec to create a registry for

Returns:

a CodecRegistry for the given list of Codec instances.

fromCodecs

public static CodecRegistry fromCodecs(java.util.List<? extends Codec<?>> codecs)

Creates a CodecRegistry from the provided list of Codec instances.

This registry can then be used alongside other registries. Typically used when adding extra codecs to existing codecs with the fromRegistries(CodecRegistry...) )} helper.

Parameters:

codecs - the Codec to create a registry for

Returns:

a CodecRegistry for the given list of Codec instances.

fromProviders

public static CodecRegistry fromProviders(CodecProvider... providers)

Creates a CodecRegistry from the provided list of CodecProvider instances.

The created instance can handle cycles of Codec dependencies, i.e when the construction of a Codec for class A requires the construction of a Codec for class B, and vice versa.

Parameters:

providers - the codec provider

Returns:

a CodecRegistry with the ordered list of CodecProvider instances. The registry is also guaranteed to be an instance of {code CodecProvider}, so that when one is passed to fromRegistries(CodecRegistry...) or fromRegistries(java.util.List) it will be treated as a CodecProvider and properly resolve any dependencies between registries.

fromProviders

public static CodecRegistry fromProviders(java.util.List<? extends CodecProvider> providers)

Creates a CodecRegistry from the provided list of CodecProvider instances.

The created instance can handle cycles of Codec dependencies, i.e when the construction of a Codec for class A requires the construction of a Codec for class B, and vice versa.

Parameters:

providers - the codec provider

Returns:

a CodecRegistry with the ordered list of CodecProvider instances. The registry is also guaranteed to be an instance of {code CodecProvider}, so that when one is passed to fromRegistries(CodecRegistry...) or fromRegistries(java.util.List) it will be treated as a CodecProvider and properly resolve any dependencies between registries.

fromRegistries

public static CodecRegistry fromRegistries(CodecRegistry... registries)

A CodecRegistry that combines the given CodecRegistry instances into a single registry.

The registries are checked in order until one returns a Codec for the requested Class.

The created instance can handle cycles of Codec dependencies, i.e when the construction of a Codec for class A requires the construction of a Codec for class B, and vice versa.

Any of the given registries that also implement CodecProvider will be treated as a CodecProvider instead of a CodecRegistry, which will ensure proper resolution of any dependencies between registries.

Parameters:

registries - the preferred registry for Codec lookups

Returns:

a CodecRegistry that combines the list of CodecRegistry instances into a single one

fromRegistries

public static CodecRegistry fromRegistries(java.util.List<? extends CodecRegistry> registries)

A CodecRegistry that combines the given CodecRegistry instances into a single registry.

The registries are checked in order until one returns a Codec for the requested Class.

The created instance can handle cycles of Codec dependencies, i.e when the construction of a Codec for class A requires the construction of a Codec for class B, and vice versa.

Any of the given registries that also implement CodecProvider will be treated as a CodecProvider instead of a CodecRegistry, which will ensure proper resolution of any dependencies between registries.

Parameters:

registries - the preferred registry for Codec lookups

Returns:

a CodecRegistry that combines the list of CodecRegistry instances into a single one
