public final class HeaderlessChannelWriterOutputView
extends org.apache.flink.runtime.io.disk.iomanager.AbstractChannelWriterOutputView

A DataOutputView that is backed by a BlockChannelWriter, making it effectively a data output stream. The view writes its data in blocks to the underlying channel, but does not expect header for each block.
