setZeroCopy

public void setZeroCopy(FileChannel fileChannel,

设置零拷贝传输数据。调用后，Packet 将使用指定的 FileChannel 以及文件长度进行零拷贝传输， 发送时框架需要检测 isZeroCopy() 为 true 时使用底层的零拷贝方法。

Parameters:

fileChannel - 零拷贝传输使用的文件通道

fileLength - 传输数据的长度

isZeroCopy

public boolean isZeroCopy()

是否启用了零拷贝传输

Returns:

true 如果使用零拷贝传输

getZeroCopyFileChannel

public FileChannel getZeroCopyFileChannel()

返回零拷贝传输使用的 FileChannel 对象

Returns:

FileChannel 对象

getZeroCopyFileLength

public long getZeroCopyFileLength()

返回零拷贝传输的数据长度

Returns:

数据长度

clearZeroCopy

public void clearZeroCopy()

清除零拷贝传输设置
