org.xnio.channels.BlockingWritableByteChannel

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable, Channel, GatheringByteChannel, WritableByteChannel

public class BlockingWritableByteChannel
extends Object
implements GatheringByteChannel, Flushable

A blocking wrapper for a StreamChannel. Write operations will block until some data may be transferred. Once any amount of data is written, the operation will return.
