本文整理了Java中io.netty.buffer.ByteBuf.retainedSlice()方法的一些代码示例，展示了ByteBuf.retainedSlice()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ByteBuf.retainedSlice()方法的具体详情如下：
包路径：io.netty.buffer.ByteBuf
类名称：ByteBuf
方法名：retainedSlice

ByteBuf.retainedSlice介绍

[英]Returns a retained slice of this buffer's readable bytes. Modifying the content of the returned buffer or this buffer affects each other's content while they maintain separate indexes and marks. This method is identical to buf.slice(buf.readerIndex(), buf.readableBytes()). This method does not modify readerIndex or writerIndex of this buffer.

Note that this method returns a #retain() buffer unlike #slice(). This method behaves similarly to slice().retain() except that this method may return a buffer implementation that produces less garbage.
[中]返回此缓冲区的可读字节的保留片。修改返回的缓冲区或此缓冲区的内容会影响彼此的内容，同时它们会维护单独的索引和标记。此方法与buf相同。切片（buf.readerIndex（），buf。readableBytes（）。此方法不修改此缓冲区的readerIndex或writerIndex。
请注意，与#slice（）不同，此方法返回一个#retain（）缓冲区。此方法的行为类似于slice（）。retain（），但此方法可能返回产生较少垃圾的缓冲区实现。
