+/**
+ * GuardedBy
+ * 
+ * The field or method to which this annotation is applied can only be accessed
+ * when holding a particular lock, which may be a built-in (synchronization)
+ * lock, or may be an explicit java.util.concurrent.Lock.
+ * 
+ * The argument determines which lock guards the annotated field or method: this :
+ * The string literal "this" means that this field is guarded by the class in
+ * which it is defined. class-name.this : For inner classes, it may be necessary
+ * to disambiguate 'this'; the class-name.this designation allows you to specify
+ * which 'this' reference is intended itself : For reference fields only; the
+ * object to which the field refers. field-name : The lock object is referenced
+ * by the (instance or static) field specified by field-name.
+ * class-name.field-name : The lock object is reference by the static field
+ * specified by class-name.field-name. method-name() : The lock object is
+ * returned by calling the named nil-ary method. class-name.class : The Class
+ * object for the specified class should be used as the lock object.
