| 35 * The field or method to which this annotation is applied can only be accessed | |
| 36 * when holding a particular lock, which may be a built-in (synchronization) lock, | |
| 37 * or may be an explicit java.util.concurrent.Lock. | |
| 38 * | |
| 39 * The argument determines which lock guards the annotated field or method: | |
| 40 * <ul> | |
| 41 * <li> | |
| 42 * <code>this</code> : The intrinsic lock of the object in whose class the field is defined. | |
| 43 * </li> | |
| 44 * <li> | |
| 45 * <code>class-name.this</code> : For inner classes, it may be necessary to disambiguate 'this'; | |
| 46 * the <em>class-name.this</em> designation allows you to specify which 'this' reference is intended | |
| 47 * </li> | |
| 48 * <li> | |
| 49 * <code>itself</code> : For reference fields only; the object to which the field refers. | |
| 50 * </li> | |
| 51 * <li> | |
| 52 * <code>field-name</code> : The lock object is referenced by the (instance or static) field | |
| 53 * specified by <em>field-name</em>. | |
| 54 * </li> | |
| 55 * <li> | |
| 56 * <code>class-name.field-name</code> : The lock object is reference by the static field specified | |
| 57 * by <em>class-name.field-name</em>. | |
| 58 * </li> | |
| 59 * <li> | |
| 60 * <code>method-name()</code> : The lock object is returned by calling the named nil-ary method. | |
| 61 * </li> | |
| 62 * <li> | |
| 63 * <code>class-name.class</code> : The Class object for the specified class should be used as the lock object. | |
| 64 * </li> | |
| 65 * <p> | |
| 66 * Based on code developed by Brian Goetz and Tim Peierls and concepts | |
| 67 * published in 'Java Concurrency in Practice' by Brian Goetz, Tim Peierls, | |
