ComLib Class

The ComLib Class of the com.ms.com package contains routines that are used during Java Component Object Model (COM) integration. All ComLib methods are static; therefore, you can use this class without instantiating it.

public class ComLib
{
  // Methods
  public native static void declareMessagePumpThread();
  public static native void executeOnContext(Object objectWithContext,
        Runnable runnable);
  public static native void freeUnusedLibraries();
  public static _Guid getGuidOf(Class cl);
  public static native boolean isEqualUnknown(Object o1, Object o2);
  public native static int jcdwClassOffsetOf(Class cls,
        String fieldName);
  public native static int jcdwClassSizeOf(Class cls);
  public native static int jcdwOffsetOf(Object jcdw,
        String fieldName);
  public native static int jcdwSizeOf(Object jcdw);
  public native static Object makeProxyRef(Object o);
  public static boolean ownsCleanup(Object structObj);
  public static native int ptrRelease(int ptr);
  public static native Object ptrToStruct(Class structClass,
        int ptr, boolean fFreeIndirectNativeMemory);
  public static native Object ptrToUnknown(Class unknownClass, int ptr,
        boolean isFreeThreaded);
  public native static void release(Object o);
  protected static native void setDataWrapperSize(
        Object DataWrapper, int cb);
  public native static boolean supportsInterface(Object pComObject,
        _Guid iid);
  public static native void startMTAThread(Thread thd);
  public static native void threadStartMTA(Thread thd);
  public static native int unknownToPtr(Object obj, _Guid iid);

  // Fields
  public static final _Guid IID_IUnknown;
  public static final _Guid IID_IDispatch;
