copy

JmsMapMessageFacade copy()
                  throws jakarta.jms.JMSException

a deep copy of this Message Facade including a complete copy of the byte contents of the wrapped message.

Throws:

jakarta.jms.JMSException - if an error occurs while copying this message.

getMapNames

java.util.Enumeration<java.lang.String> getMapNames()

Returns an Enumeration of all the names in the MapMessage object.

Returns:

an enumeration of all the names in this MapMessage

itemExists

boolean itemExists(java.lang.String key)

Determines whether an item exists in this Map based message.

key - The entry key that is being searched for.

Returns:

true if the item exists in the Map, false otherwise.

get

java.lang.Object get(java.lang.String key)

Gets the value stored in the Map at the specified key.

the item associated with the given key, or null if not present.

put

void put(java.lang.String key,
         java.lang.Object value)
