Detailed Description

This class allows tracing to performed of the calls made within the paho-c library.

One instantiates an instance of the tracer and attaches an instance of Net.MQTT.Logger by setting the Logger property. The Tracer class then delegates log requests to the Logger class. If you don't provide a Logger instance then the default implementation uses this class (which is itself a logger) to perform the logging with a default implementation that just writes to the console.

OnNew()

_.Library.Status OnNew ( )

private

This callback method is invoked by the <METHOD>New</METHOD> method to.

provide notification that a new instance of an object is being created.

If this method returns an error then the object will not be created.

It is passed the arguments provided in the New call. When customizing this method, override the arguments with whatever variables and types you expect to receive from New(). For example, if you're going to call New, passing 2 arguments, OnNew's signature could be:

Method OnNew(dob as Date = "", name as Name = "") as Status If instead of returning a Status code this returns an oref and this oref is a subclass of the current class then this oref will be the one returned to the caller of New method.

Reimplemented from RegisteredObject.
