Hi,
I need to develop a tool that acquires a list of HPROF dump stored on the disk and perform a series of analyses on them.
I tried to strictly follow the (very poor) documentation found on the document "How to write extensions for Memory Analyzer", and I came up only with a new empty Eclipse RCP application .

I have just few questions:
Could you please give me some insights about how to put an "Acquire heap dump" function from hard disk?

I tried to start with this plugin:
package matextension;

import org.eclipse.mat.SnapshotException;
import org.eclipse.mat.snapshot.extension.IClassSpecificNameResolver;
import org.eclipse.mat.snapshot.extension.Subject;
import org.eclipse.mat.snapshot.model.IObject;
@Subject("java.lang.Runtime")

public class MATResolver1 implements IClassSpecificNameResolver {

public MATResolver1() {
// TODO Auto-generated constructor stub
}

public String resolve(IObject object) throws SnapshotException {
// TODO Auto-generated method stub
System.out.println(object.getUsedHeapSize());
return "The Java runtime of size"+object.getUsedHeapSize();
}

}

How could I test that this code is actually working?

Thanks,
Francesco
