Webb在这个示例中，我们使用了FileChannel类和ByteBuffer类来完成文件的读取。首先，我们通过FileInputStream类创建了一个输入流对象，然后通过getChannel()方法获取到对应的通道对象；接着，我们创建了一个容量为1024字节的ByteBuffer对象，并调用read()方法从通道中读取数据，将读取到的数据保存在缓冲区中。 WebbJava NIO Datagram is used as channel which can send and receive UDP packets over a connection less protocol.By default datagram channel is blocking while it can be use in non blocking mode.In order to make it non-blocking we can use the configureBlocking (false) method.DataGram channel can be open by calling its one of the static method named …
WebbNIO Buffers If a ByteBuf can be converted into an NIO ByteBuffer which shares its content (i.e. view buffer), you can get it via the nioBuffer() method. To determine if a buffer can be converted into an NIO buffer, use nioBufferCount(). Strings Various toString(Charset) methods convert a ByteBuf into a String.
