Method Detail

string

static BodyCodec<String> string()

Returns:

the UTF-8 string codec

string

static BodyCodec<String> string(String encoding)

A codec for strings using a specific encoding.

Parameters:

encoding - the encoding

Returns:

the codec

buffer

static BodyCodec<Buffer> buffer()

Returns:

the Buffer codec

jsonObject

static BodyCodec<JsonObject> jsonObject()

Returns:

the JsonObject codec

jsonArray

static BodyCodec<JsonArray> jsonArray()

Returns:

the JsonArray codec

json

static <U> BodyCodec<U> json(Class<U> type)

Create and return a codec for Java objects encoded using Jackson mapper.

Returns:

a codec for mapping POJO to Json

none

static BodyCodec<Void> none()

Returns:

a codec that simply discards the response

create

static <T> BodyCodec<T> create(java.util.function.Function<Buffer,T> decode)

Create a codec that buffers the entire body and then apply the decode function and returns the result.

Parameters:

decode - the decode function

Returns:

the created codec

pipe

static BodyCodec<Void> pipe(WriteStream<Buffer> stream)

A body codec that pipes the body to a write stream.

Same as pipe(stream, true).

Parameters:

stream - the destination tream

Returns:

the body codec for a write stream

pipe

static BodyCodec<Void> pipe(WriteStream<Buffer> stream,
                            boolean close)

A body codec that pipes the body to a write stream.

Parameters:

stream - the destination stream

close - whether the destination stream should be closed

Returns:

the body codec for a write stream

create

void create(Handler<AsyncResult<BodyStream<T>>> handler)

Create the BodyStream.

This method is usually called for creating the pump for the HTTP response and should not be called directly.
