Class AdapterCodec

java.lang.Object

com.github.mizosoft.methanol.AdapterCodec

public final class AdapterCodec
extends Object

A group of adapters (encoders & decoders), typically targeting different mapping schemes, that facilitates creating corresponding HttpRequest.BodyPublisher, HttpResponse.BodyHandler and HttpResponse.BodySubscriber implementations. The correct adapter is selected based on the object type and caller's BodyAdapter.Hints, typically containing the MediaType of the desired mapping format.

Method Details

encoders

public List<BodyAdapter.Encoder> encoders()

Returns the list of encoders in this codec.

decoders

public List<BodyAdapter.Decoder> decoders()

Returns the list of decoders in this codec.

publisherOf

public <T> HttpRequest.BodyPublisher publisherOf(T value,
 BodyAdapter.Hints hints)

Returns a HttpRequest.BodyPublisher that encodes the given object into a request body.

Throws:

UnsupportedOperationException - if no encoder that supports encoding the given object or is compatible with the given hints' media type (if any) is found

publisherOf

public <T> HttpRequest.BodyPublisher publisherOf(T value,
 TypeRef<T> typeRef,
 BodyAdapter.Hints hints)

Returns a HttpRequest.BodyPublisher that encodes the given object into a request body with respect to the given TypeRef.

Throws:

UnsupportedOperationException - if no encoder that supports encoding the given object type or is compatible with the given hints' media type (if any) is found

IllegalArgumentException - if the given object is not an instance of the given TypeRef's raw type

subscriberOf

public <T> HttpResponse.BodySubscriber<T> subscriberOf(TypeRef<T> typeRef,
 BodyAdapter.Hints hints)

Returns a HttpResponse.BodySubscriber that decodes the response body into an object of the given type.

Throws:

UnsupportedOperationException - if no decoder that supports decoding to the given type or is compatible with the given hints' media type (if any) is found

deferredSubscriberOf

public <T> HttpResponse.BodySubscriber<Supplier<T>> deferredSubscriberOf(TypeRef<T> typeRef,
 BodyAdapter.Hints hints)

Returns a HttpResponse.BodySubscriber that lazily decodes the response body into an object of the given type.

Throws:

UnsupportedOperationException - if no decoder that supports decoding to the given type or is compatible with the given hints' media type (if any) is found

handlerOf

public <T> HttpResponse.BodyHandler<T> handlerOf(TypeRef<T> typeRef,
 BodyAdapter.Hints hints)

Returns a HttpResponse.BodyHandler that decodes the response body into an object of the given type. The decoder is selected based on the response body's media type as specified by the Content-Type header. If no such header exists, any decoder that supports decoding to the given type is selected.

Throws:

UnsupportedOperationException - if no decoder that supports decoding to the given type is found

deferredHandlerOf

public <T> HttpResponse.BodyHandler<Supplier<T>> deferredHandlerOf(TypeRef<T> typeRef,
 BodyAdapter.Hints hints)

Returns a BodyHandler that lazily decodes the response body into an object of the given type. The decoder is selected based on the response body's media type as specified by the Content-Type header. If no such header exists, any decoder that supports decoding to the given type is selected.

Throws:

UnsupportedOperationException - if no decoder that supports decoding to the given type is found

toString

public String toString()

Overrides:

toString in class Object

installed

public static AdapterCodec installed()

newBuilder

public static AdapterCodec.Builder newBuilder()

Returns a new AdapterCodec.Builder.
