- * cleanly inherit through their getters, and the inspector runtime will read the properties of a
- * parent class via the parent's inspection helper, and the child helper will only read properties
- * added or changed since the parent was defined.
- *
- * Only one child traversal is considered for each class. If a descendant class defines a
- * different child traversal than its parent, only the bottom traversal is used. If a class does
- * not define its own child traversal, but one of its ancestors does, the bottom-most ancestor's

+ * Note: This file is copied from dalvik.system package with the following modifications:
+ *       - Remove @CorePlatformApi, @IntraCoreApi and @UnsupportedAppUsage annotations.
+ *       - Replace System.logW() with android.util.Log.w().

+ *       b/120419300
+ *
+ * CloseGuard is a mechanism for flagging implicit finalizer cleanup of
+ * resources that should have been cleaned up by explicit close
+ * methods (aka "explicit termination methods" in Effective Java).
+ * <p>
+ * A simple example: <pre>   {@code
+ *   class Foo {
+ *
+ *       {@literal @}ReachabilitySensitive
+ *       private final CloseGuard guard = CloseGuard.get();
+ *
+ *       ...
+ *
+ *       public Foo() {
+ *           ...;
+ *           guard.open("cleanup");
+ *       }
+ *
+ *       public void cleanup() {
+ *          guard.close();
+ *          ...;
+ *       }
+ *
+ *       protected void finalize() throws Throwable {
+ *           try {
+ *               // Note that guard could be null if the constructor threw.
+ *               if (guard != null) {
+ *                   guard.warnIfOpen();
+ *               }
+ *               cleanup();
+ *           } finally {
+ *               super.finalize();
+ *           }
+ *       }
+ *   }
+ * }</pre>
+ *
+ * In usage where the resource to be explicitly cleaned up is
+ * allocated after object construction, CloseGuard protection can
+ * be deferred. For example: <pre>   {@code
+ *   class Bar {
+ *
+ *       {@literal @}ReachabilitySensitive
+ *       private final CloseGuard guard = CloseGuard.get();
+ *
+ *       ...
+ *
+ *       public Bar() {
+ *           ...;
+ *       }
+ *
+ *       public void connect() {
+ *          ...;
+ *          guard.open("cleanup");
+ *       }
+ *
+ *       public void cleanup() {
+ *          guard.close();
+ *          ...;
+ *       }
+ *
+ *       protected void finalize() throws Throwable {
+ *           try {
+ *               // Note that guard could be null if the constructor threw.
+ *               if (guard != null) {
+ *                   guard.warnIfOpen();
+ *               }
+ *               cleanup();
+ *           } finally {
+ *               super.finalize();
+ *           }
+ *       }
+ *   }
+ * }</pre>
+ *
+ * When used in a constructor, calls to {@code open} should occur at
+ * the end of the constructor since an exception that would cause
+ * abrupt termination of the constructor will mean that the user will
+ * not have a reference to the object to cleanup explicitly. When used
+ * in a method, the call to {@code open} should occur just after
+ * resource acquisition.
+ *
+ * The @ReachabilitySensitive annotation ensures that finalize() cannot be
+ * called during the explicit call to cleanup(), prior to the guard.close call.
+ * There is an extremely small chance that, for code that neglects to call
+ * cleanup(), finalize() and thus cleanup() will be called while a method on
+ * the object is still active, but the "this" reference is no longer required.
+ * If missing cleanup() calls are expected, additional @ReachabilitySensitive
+ * annotations or reachabilityFence() calls may be required.
