Quick check: is JpfThreadStatusDataProvider.ID equal to org.eclipse.tracecompass.incubator.internal.jpftrace.ui.view.JpfThreadStatusDataProviderFactory (the id in your factory declaration in plugin.xml)?
These 2 values should match.
Hi,
I'm implementing a new trace type and try to visualize it by extending the control flow view, but I encountered some problems and would like to ask your help.
Formerly my trace implements IKernelTrace so it could be drawn by the Control Flow View.
Now I want to make my own trace events types(not only the ones in DefaultEventLayout) such as thread_wait, thread_notify, etc. I also expect to draw more elements on the chart denoting these type of events.
Now I created a ui module for my trace, the view class extends ControlFlowView, and override the getProviderId() function by returning the ID of my extended JpfThreadStatusDataProvider:
@Override
protected String getProviderId() {
return JpfThreadStatusDataProvider.ID;
}
I've also created a factory for my data provider and try to hook it to the dataprovider point in plugin.xml, and I do like this:
<extension
point="org.eclipse.tracecompass.tmf.core.dataprovider">
<dataProviderFactory
class="org.eclipse.tracecompass.incubator.internal.jpftrace.ui.view.JpfThreadStatusDataProviderFactory"
id="org.eclipse.tracecompass.incubator.internal.jpftrace.ui.view.JpfThreadStatusDataProviderFactory">
</dataProviderFactory>
</extension>
But from the running and logging, I could see that:
* My view window could be opened, but there's nothing in it.
(there should be a graph at least the same
as the control flow view if it works)
* The JpfTraceControlFlowView is constructed, and the overrided getProviderId() is called;
* The function createProvider() of my data provider factory is never called;
so my JpfThreadStatusDataProvider is not instantiated.
How should I check if I miss anything for it to work? Or should I do it in another way to create the expected features?
Thank you a lot in advance,
Yang
