reference-counted formula*. One can't call constructors for AST items anymore, everything need to be acquired through instance() class methods. * src/ltlast/formula.cc, src/ltlast/refformula.cc, src/ltlast/refformula.hh: New files. * src/ltlast/Makefile.am (libltlast_la_SOURCES): Add them. * src/ltlast/atomic_prop.cc, src/ltlast/atomic_prop.hh, src/ltlast/unop.cc, src/ltlast/unop.hh, src/ltlast/binop.cc, src/ltlast/binop.hh: Make the constructor and destructor protected. Define a static function `instance()' to get an instance with specific argument. Use a map called `instances' to store all known instances. Inherit from ref_formula. * src/ltlast/constant.hh, src/ltlast/constant.cc: Protect the constructor and destructor. Provide the false_instance() and true_instance() functions instead. * src/formula.hh (ref, unref, ref_, unref_): New methods. * src/ltlast/multop.cc, src/ltlast/multop.hh: Protect the constructor, destructor, as well as the add() method. Provides the instance(), and add() class methods instead. Store children_ as a pointer. * src/ltlenv/defaultenv.cc (require): Adjust to call atomic_prop::instance. * src/ltlparse/ltlparse.yy: Adjust to call instance() functions instead of constructors. * src/ltltest/Makefile.am (LDADD): Tweak library ordering. * src/ltlvisit/clone.hh (clone_visitor): Inherit from visitor, not const_visitor, and adjust all prototypes appropriately. * src/ltlvisit/clone.cc (clone_visitor): Likewise. Call ref() or instance() methods instead of copy constructors. * src/ltlvisit/equals.cc: Simplify atomic_prop and constant cases. * src/ltlvisit/lunabbrev.hh, src/ltlvisit/lunabbrev.cc, src/ltlvisit/tunabbrev.hh, src/ltlvisit/tunabbrev.cc, src/ltlvisit/nenoform.hh, src/ltlvisit/nenoform.cc: Use instance() methods instead of constructor. Make these children of visitor, not const_visitor. * src/ltltest/readltl.c (main): Do not delete the formula. |
