Method Detail

readBytes

public static Single<byte[]> readBytes(Flow.Publisher<DataChunk> chunks)

Collect the DataChunk of the given publisher into a single byte array.

Parameters:

chunks - source publisher

Returns:

Single

readString

public static Single<String> readString(Flow.Publisher<DataChunk> chunks,
                                        Charset charset)

Convert the given publisher of DataChunk into a String.

Parameters:

chunks - source publisher

charset - charset to use for decoding the bytes

Returns:

Single

readURLEncodedString

public static Single<String> readURLEncodedString(Flow.Publisher<DataChunk> chunks,
                                                  Charset charset)

Convert the publisher of DataChunk into a String processed through URL decoding.

Parameters:

chunks - source publisher

charset - charset to use for decoding the input

Returns:

Single

stringReader

public static Reader<String> stringReader(Charset charset)

Get a reader that converts a DataChunk publisher to a String.

Parameters:

charset - the charset to use with the returned string content reader

Returns:

a string content reader

urlEncodedStringReader

public static Reader<String> urlEncodedStringReader(Charset charset)

Gets a reader that converts a DataChunk publisher to a String processed through URL decoding.

Parameters:

charset - the charset to use with the returned string content reader

Returns:

the URL-decoded string content reader

byteArrayReader

public static Reader<byte[]> byteArrayReader()

Get a reader that converts a DataChunk publisher to an array of bytes.

Returns:

reader that transforms a publisher of byte buffers to a completion stage that might end exceptionally with

inputStreamReader

public static Reader<InputStream> inputStreamReader()

Get a reader that converts a DataChunk publisher to a blocking Java InputStream. The resulting CompletionStage is already completed; however, the referenced InputStream in it may not already have all the data available; in such case, the read method (e.g., InputStream.read()) block.

Returns:

a input stream content reader
