Modifier and Type	Method and Description
`protected boolean`	`closeOnReadError(java.lang.Throwable cause)`
`protected boolean`	`continueOnWriteError()` 如果我们应该在写入错误时继续写入循环，则返回 `true` 。
`protected void`	`doBeginRead()` 安排读取操作。
`protected abstract int`	`doReadMessages(java.util.List<java.lang.Object> buf)` 将消息读入给定数组并返回读取的数量。
`protected void`	`doWrite(ChannelOutboundBuffer in)` 将给定缓冲区的内容刷新到远程对等体。
`protected abstract boolean`	`doWriteMessage(java.lang.Object msg, ChannelOutboundBuffer in)` 写下消息到底层 `Channel` 。
`protected AbstractNioChannel.AbstractNioUnsafe`	`newUnsafe()` 创建一个新的`AbstractChannel.AbstractUnsafe`实例，该实例将用于`Channel`的生命周期
