</persistent>
<super
type="org.eclipse.core.resources.bookmark">
</super>
<super
type="org.eclipse.core.resources.textmarker">
</super>
<attribute
name="type">
</attribute>
<attribute
name="start_line">
</attribute>
<attribute
name="end_line">
</attribute>
<attribute
name="xpath">
</attribute>
</extension>
In one class I create a map of attributes and create the marker as follows:
attributes.put("end_line", new Integer(_loc.getLineNumber()));
attributes.put(IMarker.CHAR_END, new Integer(_loc.getColumnNumber()));
MarkerUtilities.createMarker(_resource, attributes, "XMLValueMarker");
In another I try to get the markers I've created:
IMarker[] tmp = file.findMarkers("XMLValueMarker", true, 5);
for(int i = 0; i < tmp.length; ++i) {
System.err.println("Marker found: " + tmp[i].getAttribute("xpath",
"n/a"));
}
The problem is that the call to findMarkers is returning an empty array.
Where have I gone wrong?
Geoff.

I changed the code to use IResource.DEPTH_ZERO as below, but I'm still
not getting any markers.
And yes, file is really a file. It is the same object that the markers
were added to.
IMarker[] tmp = file.findMarkers("XMLValueMarker", true,
IResource.DEPTH_ZERO);
for(int i = 0; i < tmp.length; ++i) {
System.err.println("Marker found: " + tmp[i].getAttribute("xpath",
"n/a"));
}

Geoff,
first of all the ID of your marker is <pluginID>+".XMLValueMarker"
(unless you fully qualify the ID the plug-in ID will be added).
Does the creation of the marker work i.e. no exception?
Is the file/resource really the same?
Try the following code to see whether the marker has been created
somewhere in your workspace:
ResourcesPlugin.getWorkspace().getRoot().findMarkers(<markerID >, true,
IResource.DEPTH_INFINITE);

I've tried with both fully qualified and short and neither seemed to work.

No exceptions. Not that I can see anyway.

Yes.

Still no markers.

Put a breakpoint in createMarker and start in debug mode to verify that
the marker is created. Then put a breakpoint in findMarkers to see why
your breakpoint is not found.

How can I tell if the markers have been created?
What object, if any, do they get added to?
If they don't get added to an object how can I view them in the debugger?

OK. The markers are being created.
When using:
findMarkers("com.decisionsoft.xmeta.ui.infoeditor.XMLValueMarker ", true,
IResource.DEPTH_INFINITE);
it goes as deep as the
basicFindMatching in org.eclipse.core.internal.resources.MarkerManager
Within this method it contains the code:
if (includeSubtypes) {
if (cache.isSubtype(marker.getType(), type))
result.add(marker);
} else {
if (marker.getType().equals(type))
result.add(marker);
}
Because I specified to find subtypes, it checks the marker to see if it
is a subtype and fails.
Should this not check the types are equal as well as checking if its a
subtype?
If I use:
findMarkers("com.decisionsoft.xmeta.ui.infoeditor.XMLValueMarker ",
false, IResource.DEPTH_INFINITE);
Then the markers are found.
Geoff.

It does (see IMarker.isSubtypes()). I guess the test fails because of a
typo (the ID in the code does not match to the one in the XML). Step
again into above code and inspect the cache to see which markers it
contains. I assume you will find one similar spelled to yours.

then the MarkerManager stores a definition of
" com.decisionsoft.xmeta.ui.infoeditor.com.decisionsoft.xmeta. ui.infoeditor.XMLValueMarker "
But if I use id="XMLValueMarker" no definition at all is stored.
The ID is the only thing I change.
Any thoughts?
Geoff.

Not without seeing your whole plugin.xml. Using unqualified names should
be OK (see other plugin.xmls).
