Example 1 with Queue

Example 2 with Queue

use of org.apache.qpid.server.model.Queue in project qpid by apache.

the class QmfManagementAgent method childAdded.

/**
 * ConfigurationChangeListener method called when a child ConfiguredObject is added.
 * <p>
 * This method checks the type of the child ConfiguredObject that has been added and creates the equivalent
 * QMF2 Management Object if one doesn't already exist. In most cases it's a one-to-one mapping, but for
 * Binding for example the Binding child is added to both Queue and Exchange so we only create the Binding
 * QMF2 Management Object once and add the queueRef and exchangeRef reference properties referencing the Queue
 * and Exchange parent Objects respectively, Similarly for Consumer (AKA Subscription).
 * <p>
 * This method is also responsible for raising the appropriate QMF2 Events when Management Objects are created.
 * @param object the parent object that the child is being added to.
 * @param child the child object being added.
