clingo_ground_program_observer

! An instance of this struct has to be registered with a solver to observe ground directives as they are passed to the solver. ! ! @note This interface is closely modeled after the aspif format. ! For more information please refer to the specification of the aspif format. ! ! Not all callbacks have to be implemented and can be set to NULL if not needed. ! If one of the callbacks in the struct fails, grounding is stopped. ! If a non-recoverable clingo API call fails, a callback must return false. ! Otherwise ::clingo_error_unknown should be set and false returned. ! ! @see clingo_control_register_observer()

clingo_location

! Represents a source code location marking its beginnig and end. ! ! @note Not all locations refer to physical files. ! By convention, such locations use a name put in angular brackets as filename.

clingo_model
clingo_options
clingo_part

! Struct used to specify the program parts that have to be grounded. ! ! Programs may be structured into parts, which can be grounded independently with ::clingo_control_ground. ! Program parts are mainly interesting for incremental grounding and multi-shot solving. ! For single-shot solving, program parts are not needed. ! ! @note Parts of a logic program without an explicit \#program ! specification are by default put into a program called base without ! arguments. ! ! @see clingo_control_ground()

clingo_program_builder
clingo_propagate_control
clingo_propagate_init
clingo_propagator

! An instance of this struct has to be registered with a solver to implement a custom propagator. ! ! Not all callbacks have to be implemented and can be set to NULL if not needed. ! @see Propagator

clingo_assignment_t

! Represents a (partial) assignment of a particular solver. ! ! An assignment assigns truth values to a set of literals. ! A literal is assigned to either @link clingo_assignment_truth_value() true or false, or is unassigned@endlink. ! Furthermore, each assigned literal is associated with a @link clingo_assignment_level() decision level@endlink. ! There is exactly one @link clingo_assignment_decision() decision literal@endlink for each decision level greater than zero. ! Assignments to all other literals on the same level are consequences implied by the current and possibly previous decisions. ! Assignments on level zero are immediate consequences of the current program. ! Decision levels are consecutive numbers starting with zero up to and including the @link clingo_assignment_decision_level() current decision level@endlink.

clingo_model_t

! Object representing a model.

clingo_model_type

! Enumeration for the different model types.

clingo_model_type_t

! Corresponding type to ::clingo_model_type.

clingo_options_t

! Object to add command-line options.

clingo_part_t
clingo_program_builder_t

! Object to build non-ground programs.

clingo_propagate_control_t

! This object can be used to add clauses and propagate literals while solving.

clingo_propagate_init_t

! Object to initialize a user-defined propagator before each solving step. ! ! Each @link SymbolicAtoms symbolic@endlink or @link TheoryAtoms theory atom@endlink is uniquely associated with an aspif atom in form of a positive integer (@ref ::clingo_literal_t). ! Aspif literals additionally are signed to represent default negation. ! Furthermore, there are non-zero integer solver literals (also represented using @ref ::clingo_literal_t). ! There is a surjective mapping from program atoms to solver literals. ! ! All methods called during propagation use solver literals whereas clingo_symbolic_atoms_literal() and clingo_theory_atoms_atom_literal() return program literals. ! The function clingo_propagate_init_solver_literal() can be used to map program literals or @link clingo_theory_atoms_element_condition_id() condition ids@endlink to solver literals.

clingo_propagator_check_callback_t

! Typedef for @ref ::clingo_propagator::check().

clingo_propagator_check_mode

clingo_propagator_check_mode_t

! Corresponding type to ::clingo_propagator_check_mode.

clingo_propagator_init_callback_t

! Typedef for @ref ::clingo_propagator::init().

clingo_propagator_propagate_callback_t

! Typedef for @ref ::clingo_propagator::propagate().

clingo_propagator_t
clingo_propagator_undo_callback_t

! Typedef for @ref ::clingo_propagator::undo().

clingo_show_type

! Enumeration of bit flags to select symbols in models.

clingo_show_type_bitset_t

! Corresponding type to ::clingo_show_type.

clingo_signature_t

! Represents a predicate signature. ! ! Signatures have a name and an arity, and can be positive or negative (to ! represent classical negation).

clingo_solve_control_t

! Object to add clauses during search.

clingo_solve_event_callback_t

! Callback function called during search to notify when the search is finished or a model is ready. ! ! If a (non-recoverable) clingo API function fails in this callback, it must return false. ! In case of errors not related to clingo, set error code ::clingo_error_unknown and return false to stop solving with an error. ! ! The event is either a pointer to a model, a pointer to two statistics objects (per step and accumulated statistics), or a solve result. ! @attention If the search is finished, the model is NULL. ! ! @param[in] event the current event. ! @param[in] data user data of the callback ! @param[out] goon can be set to false to stop solving ! @return whether the call was successful ! ! @see clingo_control_solve()

clingo_solve_event_type

! Enumeration of solve events.

clingo_solve_event_type_t

! Corresponding type to ::clingo_solve_event_type.

clingo_solve_handle_t

! Search handle to a solve call. ! ! @see clingo_control_solve()

clingo_solve_mode

! Enumeration of solve modes.

clingo_solve_mode_bitset_t

! Corresponding type to ::clingo_solve_mode.

clingo_solve_result

! Corresponding type to ::clingo_statistics_type.

clingo_symbol_callback_t

! Callback function to inject symbols. ! ! @param symbols array of symbols ! @param symbols_size size of the symbol array ! @param data user data of the callback ! @return whether the call was successful; might set one of the following error codes: ! - ::clingo_error_bad_alloc ! @see ::clingo_ground_callback_t

clingo_symbol_t

! Represents a symbol. ! ! This includes numbers, strings, functions (including constants when ! arguments are empty and tuples when the name is empty), \#inf and \#sup.

clingo_symbol_type

! Enumeration of available symbol types.

clingo_symbol_type_t

! Corresponding type to ::clingo_symbol_type.

clingo_symbolic_atom_iterator_t

! Object to iterate over symbolic atoms. ! ! Such an iterator either points to a symbolic atom within a sequence of ! symbolic atoms or to the end of the sequence. ! ! @note Iterators are valid as long as the underlying sequence is not modified. ! Operations that can change this sequence are ::clingo_control_ground(), ! ::clingo_control_cleanup(), and functions that modify the underlying ! non-ground program.

clingo_symbolic_atoms_t

! Object to inspect symbolic atoms in a program---the relevant Herbrand base ! gringo uses to instantiate programs. ! ! @see clingo_control_symbolic_atoms()

clingo_theory_atoms_t
