writeBytes

public static Single<DataChunk> writeBytes(byte[] bytes,
 boolean copy)

Create a DataChunk with the given byte array and return a Single.

Parameters:

bytes - the byte array

copy - if true the byte array is copied

Returns:

Single

Since:

2.0.0

writeCharSequence

public static Single<DataChunk> writeCharSequence(CharSequence cs,
 Charset charset)

Create a publisher of DataChunk with the given CharSequence / Charset and return a Single.

Parameters:

cs - the char sequence

charset - the charset to use to encode the char sequence

Returns:

Single

Since:

2.0.0

writeCharBuffer

public static Single<DataChunk> writeCharBuffer(CharBuffer buffer,
 Charset charset)

Create a a publisher DataChunk with the given CharBuffer / Charset and return a Single.

Parameters:

buffer - the char buffer

charset - the charset to use to encode the char sequence

Returns:

Single

Since:

2.0.0

writeStackTrace

public static Single<DataChunk> writeStackTrace(Throwable throwable,
 Charset charset)

Create a a publisher DataChunk with the given Throwable / Charset and return a Single.

Parameters:

throwable - the Throwable

charset - the charset to use to encode the stack trace

Returns:

Single

Since:

2.0.0

byteArrayWriter

@Deprecated(since="2.0.0")
public static Function<byte[],Flow.Publisher<DataChunk>> byteArrayWriter(boolean copy)

Deprecated.

since 2.0.0, use writeBytes(byte[], boolean) instead

Returns a writer function for byte[].

The copy variant is by default registered in ServerResponse.

Parameters:

copy - a signal if byte array should be copied - set it true if byte[] will be immediately reused.

Returns:

a byte[] writer

charSequenceWriter

@Deprecated(since="2.0.0")
public static Function<CharSequence,Flow.Publisher<DataChunk>> charSequenceWriter(Charset charset)

Deprecated.

since 2.0.0, use writeCharSequence(CharSequence, Charset) or DefaultMediaSupport.charSequenceWriter() instead

Returns a writer function for CharSequence using provided standard charset.

An instance is by default registered in ServerResponse for all standard charsets.

Parameters:

charset - a standard charset to use

Returns:

a String writer

Throws:

NullPointerException - if parameter charset is null

charBufferWriter

@Deprecated(since="2.0.0")
public static Function<CharBuffer,Flow.Publisher<DataChunk>> charBufferWriter(Charset charset)

Deprecated.

since 2.0.0, use writeCharBuffer(CharBuffer, Charset) instead

Returns a writer function for CharBuffer using provided standard charset.

An instance is by default registered in ServerResponse for all standard charsets.

Parameters:

charset - a standard charset to use

Returns:

a String writer

Throws:

NullPointerException - if parameter charset is null

byteChannelWriter

@Deprecated(since="2.0.0")
public static Function<ReadableByteChannel,Flow.Publisher<DataChunk>> byteChannelWriter(RetrySchema retrySchema)

Deprecated.

since 2.0.0, use DefaultMediaSupport.byteChannelWriter(RetrySchema)} instead

Returns a writer function for ReadableByteChannel. Created publisher use provided RetrySchema to define delay between unsuccessful read attempts.

Parameters:

retrySchema - a retry schema to use in case when read operation reads 0 bytes

Returns:

a ReadableByteChannel writer

byteChannelWriter

@Deprecated(since="2.0.0")
public static Function<ReadableByteChannel,Flow.Publisher<DataChunk>> byteChannelWriter()

Deprecated.

since 2.0.0, use DefaultMediaSupport.byteChannelWriter()} instead

Returns a writer function for ReadableByteChannel.

Returns:

a ReadableByteChannel writer
