/**
|
|
* 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:
|
|
* <ul>
|
|
* <li>
|
|
* <code>this</code> : The intrinsic lock of the object in whose class the field is defined.
|
|
* </li>
|
|
* <li>
|
|
* <code>class-name.this</code> : For inner classes, it may be necessary to disambiguate 'this';
|
|
* the <em>class-name.this</em> designation allows you to specify which 'this' reference is intended
|
|
* </li>
|
|
* <li>
|
|
* <code>itself</code> : For reference fields only; the object to which the field refers.
|
|
* </li>
|
|
* <li>
|
|
* <code>field-name</code> : The lock object is referenced by the (instance or static) field
|
|
* specified by <em>field-name</em>.
|
|
* </li>
|
|
* <li>
|
|
* <code>class-name.field-name</code> : The lock object is reference by the static field specified
|
|
* by <em>class-name.field-name</em>.
|
|
* </li>
|
|
* <li>
|
|
* <code>method-name()</code> : The lock object is returned by calling the named nil-ary method.
|
|
* </li>
|
|
* <li>
|
|
* <code>class-name.class</code> : The Class object for the specified class should be used as the lock object.
|
|
* </li>
