public class HeaderMap extends Object implements Map<String,String>
A key-value pair in this Map corresponds to a name-value pair of a MIME header. Because MIME header names are case-insensitive, this Map treats keys as case-insensitive too. Note that this violates the general contracts of Map.
The implementation of this class is optimized for well-known headers (see Headers).
For methods xGet(key), xContainsKey(key),
xPut(key,value), xRemove(key),
`key` must be a constant value defined in Headers.
For example: `map.xGet(Headers.Host);`
| Constructor and Description |

HeaderMap()
Create an empty HeaderMap instance.
|
HeaderMap(Map<String,String> m)
Create a HeaderMap instance, populated by `m`.
