Class StompHeaders

java.lang.Object

org.springframework.messaging.simp.stomp.StompHeaders

All Implemented Interfaces:

java.io.Serializable, java.util.Map<java.lang.String,java.util.List<java.lang.String>>, MultiValueMap<java.lang.String,java.lang.String>

public class StompHeaders
extends java.lang.Object
implements MultiValueMap<java.lang.String,java.lang.String>, java.io.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
