Examples of LengthFieldPrepender

io.netty.handler.codec.LengthFieldPrepender
An encoder that prepends the length of the message. The length value is prepended as a binary form.
For example, {@link LengthFieldPrepender}(2) will encode the following 12-bytes string:
```
 +----------------+ | "HELLO, WORLD" | +----------------+ 
```
into the following:
```
 +--------+----------------+ + 0x000C | "HELLO, WORLD" | +--------+----------------+ 
```
If you turned on the {@code lengthIncludesLengthFieldLength} flag in theconstructor, the encoded data would look like the following (12 (original data) + 2 (prepended data) = 14 (0xE)):
```
 +--------+----------------+ + 0x000E | "HELLO, WORLD" | +--------+----------------+ 
```
org.jboss.netty.handler.codec.frame.LengthFieldPrepender
An encoder that prepends the length of the message. The length value is prepended as a binary form. It is encoded in either big endian or little endian depending on the default {@link ByteOrder} of the current{@link ChannelBufferFactory}.
For example, {@link LengthFieldPrepender}(2) will encode the following 12-bytes string:
```
 +----------------+ | "HELLO, WORLD" | +----------------+ 
```
into the following:
```
 +--------+----------------+ + 0x000C | "HELLO, WORLD" | +--------+----------------+ 
```
If you turned on the {@code lengthIncludesLengthFieldLength} flag in theconstructor, the encoded data would look like the following (12 (original data) + 2 (prepended data) = 14 (0xE)):
```
 +--------+----------------+ + 0x000E | "HELLO, WORLD" | +--------+----------------+
