This is the usual way to declare a specification-only field; it is also possible to use the ghost modifier (see section 2.2 Model and Ghost).


Lightweight specifications come from ESC/Java.


JML also has various synonyms for these keywords; one can use pre for requires, modifies or modifiable for assignable, and post for ensures, if desired. See section 9. Method Specifications, for more details.

By an identifier, we technically mean an ident in the Java grammar. See section 4.6 Tokens, for details.
