    <h1>Hotspot SA User Interface Notes</h1>

    <h2>Workspace and Building</h2>

    <p>
      All the source code for the Serviceability Agent is in 
      <code>src/share/vm/agent</code> in the HotSport workspace 
      <code>/net/jano.sfbay/export/disk05/hotspot/ws/1.4/sa_baseline</code>
    <p>
      You can build the project by typing <code>gnumake</code> in the
      <code>src/share/vm/agent</code> directory.
    <p>
      You can also use the default build target using the Ant build file (build.xml). You can download Ant from
      <a href="http://jakarta.apache.org/ant">http://jakarta.apache.org/ant</a>. Documentation for Ant can be
      found at <a href="http://jakarta.apache.org/ant/manual/index.html">http://jakarta.apache.org/ant/manual/index.html</a>

      
    <h2>Running the project</h2>

    <ul>
      <li><code>java -cp classes sun.jvm.hotspot.HSDB</code>
      <li><code>java -cp classes sun.jvm.hotspot.bugspot.Main</code>
    </ul>

    <h2>Feedback</h2>
    <p>
      Refactoring of package hierarchy. All user interface components should be in
      the ui package. Perhaps: sun.jvm.hotspot.ui.hsdb.Main for the HSDB and
      sun.jvm.hotspot.ui.bugspot.Main for BugSpot.
    <p>
      The src\share\vm\agent area seems like a workspace so it should be organized like
      one. In particular, I'd like to suggest the following directory layout:<br>
      
    <ul>
      <li>src: All sources that are curently under the sun directory.
      <li>classes: compiled class files.
      <li>lib: Resources like images, icons and jar files.
      <li>docs: Documentation 
      <li>deploy: distribution bundles for Java Web Start.
    </ul>

    <p>
      Seems like there is a lot of redundant functionality. Between the HSDB and BugSpot. Perhaps
      this can be consolidated with a <code>javax.swing.Actions</code> architecture.

    <h2>Tasklist</h2>
    
    <p>
      <b>Stack memory pane</b>: 
      It's one of the more useful JVM debugging tools in the SA. However, it
      doesn't support any interaction with the text; the Memory Panel in BugSpot
      was written afterward (with help from Shannon) and implements proper
      selection, scrolling, and drag-and-drop, but no annotations. I'm not sure how
      to integrate the annotations with the JTable that's being used for the memory
      view; if you have suggestions here please let me know.
    <p>
      <b>Integrations with the NetBeans architecture (plug in).</b> See the
      <a href="http://openide.netbeans.org">Netbeans Open APIs homepage</a>

      
    <p>
      HSDB: Object Histogram. Column sizes should be sized according the the
      contents. i.e, The size and count columns should be narrow enought to
      handle the largest window. Since there is a lot of data, sorting
      and searching should be implemented.
    <p>

    <p>
      sun.jvm.hotspot.oops.ObjectHistogram should be the underlying data
      structure for the TableModels. It shouldnt bother with sorting the data - 
      the table model should do that. It should implement these methods:

    <pre>
      public int getSize()
      public ObjectHistogramElement getElementAt(int row);
    </pre>
    <p>
      ObjectHistogramElement should return the String that represents
      the third column
