Class FieldBreakpoint

java.lang.Object
  org.netbeans.api.debugger.Breakpoint
      org.netbeans.api.debugger.jpda.JPDABreakpoint
          org.netbeans.api.debugger.jpda.FieldBreakpoint

---

public class FieldBreakpoint
extends JPDABreakpoint

Notifies about variable change or access events.

How to use it:

    DebuggerManager.addBreakpoint (FieldBreakpoint.create (
        "org.netbeans.modules.editor.EditorPanel",
        "state",
        FieldBreakpoint.TYPE_MODIFICATION
    ));

This breakpoint stops when state field of EditorPanel class is modified.
