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
