Class MessageBytes

java.lang.Object
org.glassfish.grizzly.http.util.MessageBytes
All Implemented Interfaces:
Serializable, Cloneable
public final class MessageBytes extends Object implements Cloneable, 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.
