Class MapMessageImpl

java.lang.Object
  org.huihoo.jfox.ms.jms.message.MessageImpl
      org.huihoo.jfox.ms.jms.message.MapMessageImpl

All Implemented Interfaces:

javax.jms.MapMessage, javax.jms.Message, java.io.Serializable

public class MapMessageImpl

extends MessageImpl

implements javax.jms.MapMessage, java.io.Serializable

Description: A MapMessage object is used to send a set of name-value pairs. The names are String objects, and the values are primitive data types in the Java programming language. The entries can be accessed sequentially or randomly by name. The order of the entries is undefined. MapMessage inherits from the Message interface and adds a message body that contains a Map.
