SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
Common interface for the Plan classes. See the documentation of the individual classes for documentation of their workings and arguments.
Note: The constructors of the implementing
classes synchronize on this interface so that no
two ..._create_plan
functions are
called at the same time.
