Method Detail

createOutputStream

@Deprecated(since="2.0.0",
            forRemoval=true)
static OutputStreamMulti createOutputStream()

Deprecated, for removal: This API element is subject to removal in a future version.

Please use outputStreamMulti()

Create an OutputStream that provides the data written as a Multi.

In case there is no demand, OutputStream.write(byte[], int, int) methods are blocked until downstream request for more data.

Returns:

new Multi publisher extending OutputStream

outputStreamMulti

static OutputStreamMulti outputStreamMulti()

Create an OutputStream that provides the data written as a Multi.

In case there is no demand, OutputStream.write(byte[], int, int) methods are blocked until downstream request for more data.

Returns:

new OutputStream implementing Multi

builderOutputStream

@Deprecated(since="2.0.0",
            forRemoval=true)
static IoMulti.OutputStreamMultiBuilder builderOutputStream()

Deprecated, for removal: This API element is subject to removal in a future version.

Please use outputStreamMultiBuilder()

Creates a builder of the OutputStream that provides data written as a Multi.

Returns:

the builder

See Also:

outputStreamMulti()

outputStreamMultiBuilder

static IoMulti.OutputStreamMultiBuilder outputStreamMultiBuilder()

Creates a builder of the OutputStream that provides data written as a Multi.

Returns:

the builder

See Also:

outputStreamMulti()

createInputStream

@Deprecated(since="2.0.0",
            forRemoval=true)
static Multi<ByteBuffer> createInputStream(InputStream inputStream)

Deprecated, for removal: This API element is subject to removal in a future version.

please use multiFromStream(java.io.InputStream)

Create a Multi instance that publishes ByteBuffers from the given InputStream.

InputStream is trusted not to block on read operations, in case it can't be assured use builder to specify executor for asynchronous waiting for blocking reads. IoMulti.builder(is).executor(executorService).build().

Parameters:

inputStream - the Stream to publish

Returns:

Multi

Throws:

NullPointerException - if stream is null

multiFromStream

static Multi<ByteBuffer> multiFromStream(InputStream inputStream)

Create a Multi instance that publishes ByteBuffers from the given InputStream.

InputStream is trusted not to block on read operations, in case it can't be assured use builder to specify executor for asynchronous waiting for blocking reads. IoMulti.builder(is).executor(executorService).build().

Parameters:

inputStream - the Stream to publish

Returns:

Multi

builderInputStream

@Deprecated(since="2.0.0",
            forRemoval=true)
static IoMulti.MultiFromInputStreamBuilder builderInputStream(InputStream inputStream)

Deprecated, for removal: This API element is subject to removal in a future version.

Please use multiFromStreamBuilder(java.io.InputStream)

Creates a builder of the Multi from supplied InputStream.

Parameters:

inputStream - the Stream to publish

Returns:

the builder

multiFromStreamBuilder

static IoMulti.MultiFromInputStreamBuilder multiFromStreamBuilder(InputStream inputStream)

Creates a builder of the Multi from supplied InputStream.

Parameters:

inputStream - the Stream to publish

Returns:

the builder

multiFromByteChannel

static Multi<ByteBuffer> multiFromByteChannel(ReadableByteChannel byteChannel)

Creates a multi that reads data from the provided byte channel. The multi uses an executor service to process asynchronous reads. You can provide a custom executor service using multiFromByteChannelBuilder(java.nio.channels.ReadableByteChannel).

Parameters:

byteChannel - readable byte channel with data

Returns:

publisher of data from the provided channel

multiFromByteChannelBuilder

static IoMulti.MultiFromByteChannelBuilder multiFromByteChannelBuilder(ReadableByteChannel byteChannel)

Creates a builder of Multi from provided ReadableByteChannel.

Parameters:

byteChannel - readable byte channel with data

Returns:

fluent API builder to configure additional details
