Method Summary

Modifier and Type	Method	Description
static ByteBuffer	copy(ByteBuffer src, int start, int end)	拷贝到一个新的ByteBuffer
static ByteBuffer	copy(ByteBuffer src, int srcStart, ByteBuffer dest, int destStart, int length)	拷贝ByteBuffer
static ByteBuffer	copy(ByteBuffer src, ByteBuffer dest)	拷贝ByteBuffer
static ByteBuffer	copy(ByteBuffer src, ByteBuffer dest, int length)	拷贝ByteBuffer
static int	lineEnd(ByteBuffer buffer)	一行的末尾位置，查找位置时位移ByteBuffer到结束位置
static int	lineEnd(ByteBuffer buffer, int maxLength)	一行的末尾位置，查找位置时位移ByteBuffer到结束位置 支持的换行符如下：
static ByteBuffer	of(byte[] data)	创建新Buffer
static ByteBuffer	of(CharSequence data, Charset charset)	从字符串创建新Buffer
static CharBuffer	ofCharBuffer(int capacity)	创建CharBuffer
static byte[]	readBytes(ByteBuffer buffer)	读取剩余部分bytes
static byte[]	readBytes(ByteBuffer buffer, int maxLength)	读取指定长度的bytes 如果长度不足，则读取剩余部分，此时buffer必须为读模式
static byte[]	readBytes(ByteBuffer buffer, int start, int end)	读取指定区间的数据
static String	readLine(ByteBuffer buffer, Charset charset)	读取一行，如果buffer中最后一部分并非完整一行，则返回null 支持的换行符如下：
static String	readString(ByteBuffer buffer)	读取剩余部分并转为UTF-8编码字符串
static String	readString(ByteBuffer buffer, Charset charset)	读取剩余部分并转为字符串
static byte[]	toBytes(ByteBuffer bytebuffer)	ByteBuffer 转byte数组
