Sometimes, you may want to find an application of a given type on a node. The @@Node@@ objects provides basic access to do this, and the @@TypeId@@ mechanism the ability to identify the application. If the application objects have @@TypeId@@s, then this simple loop will find an application:

<code><pre>
Ptr<Application> app;
Ptr<MyApp> myapp = 0;
for (uint32_t x = 0; x < node->GetNApplications(); x++) {
app = node->GetApplication(x);
if (app->GetInstanceTypeId() == MyApp::GetTypeId()) {
myapp = dynamic_cast<MyApp *> (PeekPointer(app));
break;
}
}

if (myapp != 0) {
// Do something MyApp specific with it...
}
</pre></code>

Note the specific syntax of the cast---the template is of the pointer, note a @@Ptr@@.
