org.apache.tomcat.util.buf.MessageBytes
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. @author dac@eng.sun.com @author James Todd [gonzo@eng.sun.com] @author Costin Manolache
