public class MQMD1
extends com.ibm.mq.headers.internal.Header
implements MQChainable

MQMD version 1 (message descriptor) header class. This has a specialized use as the MsgDesc member of an MQXQH (transmission queue) header. Instances of MQMD1 cannot be set to version 2, but an MQMD instance can be created from an MQMD1 instance.

In addition to being able to read or write its content from a message body or byte stream, this class can get or set field values from the MQMD portion of an MQMessage object using the copyFrom or copyTo methods.
