All Implemented Interfaces:
Serializable, Map<String,List<String>>, MultiValueMap<String,String>
```
public class StompHeaders
extends Object
implements MultiValueMap<String,String>, Serializable
```
Represents STOMP frame headers.
In addition to the normal methods defined by Map, this class offers the following convenience methods:
- getFirst(String) return the first value for a header name
- add(String, String) add to the list of values for a header name
- set(String, String) set a header name to a single string value
