直接已知子类:

ChannelReaderInputView

public abstract class AbstractChannelReaderInputView
extends AbstractPagedInputView

A DataInputView that is backed by a FileIOChannel, making it effectively a data input stream. The view reads it data in blocks from the underlying channel. The view can only read data that has been written by a ChannelWriterOutputView, due to block formatting.
