所有已实现的接口:

java.io.Serializable, java.lang.Cloneable
```
public final class MessageBytes
extends java.lang.Object
implements java.lang.Cloneable, java.io.Serializable
```
This class is used to represent a subarray of bytes in an HTTP message. It represents all request/response elements. The byte/char conversions are delayed and cached. Everything is recyclable. The object can represent a byte[], a char[], or a (sub) String. All operations can be made in case sensitive mode or not.
