Method Detail

build

public Multi<ByteBuffer> build()

Description copied from interface: Builder

Build the instance from this builder.

Specified by:

build in interface Builder<Multi<ByteBuffer>>

Returns:

instance of the built type

executor

public IoMulti.MultiFromByteChannelBuilder executor(ScheduledExecutorService executor)

Configure executor service to use for scheduling reads from the channel. If an executor is configured using this method, it will not be terminated when the publisher completes.

Parameters:

executor - to use for scheduling

Returns:

updated builder instance

retrySchema

public IoMulti.MultiFromByteChannelBuilder retrySchema(RetrySchema retrySchema)

Retry schema to use when reading from the channel. If a channel read fails (e.g. no data is read), the read is scheduled using executor using the provided retry schema, to prolong the delays between retries.

By default the first delay is 0 milliseconds, incrementing by 50 milliseconds up to 250 milliseconds.

Parameters:

retrySchema - schema to use

Returns:

updated builder instance

bufferCapacity

public IoMulti.MultiFromByteChannelBuilder bufferCapacity(int bufferCapacity)

Capacity of byte buffer in number of bytes.

Parameters:

bufferCapacity - capacity of the buffer, defaults to 8 Kb

Returns:

updated builder instance
