Administration messages

In the Java code, administration messages form a class hierarchy. The base class MQeMsgObject is extended by MQeAdminMsg, from which many other administration messages are derived. The derived administration messages often use the functions that they inherit from previous levels in the object hierarchy.

In the C API a similar mechanism can be used. For example, an MQeAdminMsg can be created, and a handle returned to it. This handle can then be used to call the functions of MQeMsgObject of which it is a specialization. Similarly an MQeClientConnectionAdminMsg (a specialization of MQeMsgObject) handle can be used on an MQeAdminMsg function.
