Examples of org.apache.qpid.qmf2.agent.AgentExternal

org.apache.qpid.qmf2.common.SchemaClassId
.apache.org/qpid/qmfv2-api-proposal.html>QMF2 API Proposal.
The AgentExternal class extends the Agent class by adding interfaces that notify the application when it needs to service a request for management operations from the agent.
N.B. The author is not convinced that there is any particular advantage of the AgentExternal model over the basic Agent model and indeed the API forces some constructs that are actually likely to be less efficient, as an example sending a separate queryResponse() for each object forces a look up of a List of QmfAgentData objects keyed by the consoleHandle for each call. There is also the need to separately iterate through the List of QmfAgentData objects thus created to create the mapEncoded list needed for sending via the QMF2 protocol. There are similar inefficiencies imposed in the subscriptionIndicate() method that are not present in the Subscription code implemented in the Agent class for the "Internal Store" Agent model.
To be honest the author only bothered to implement AgentExternal for completeness and is unlikely to use it himself. @author Fraser Adams
