|
|
* 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.
