Detailed Description

The solve event handler interface.

Examples

ast.c, backend.c, and control.c.

Member Data Documentation

finish

void(* clingo_solve_event_handler::finish) (clingo_solve_result_bitset_t result, void *data)

Callback to notify that the search has finished.

This can be used for thread synchronization as the function is not called in the main thread when solving asynchronously.

Parameters

result	the solve result
data	the user data

free

void(* clingo_solve_event_handler::free) (void *data)

Callback to free the userdata of the handler.

Parameters

data	the user data

model

bool(* clingo_solve_event_handler::model) (clingo_model_t *model, void *data, bool *goon)

Call back to intercept models.

Parameters

model	the model
data	the user data
goon	whether to stop or continue

Returns

whether the call was successful

stats

bool(* clingo_solve_event_handler::stats) (clingo_stats_t *stats, void *data)

Callback to extend statistics.

Parameters

stats	the stats object
data	the user data

Returns

whether the call was successful

unsat

bool(* clingo_solve_event_handler::unsat) (int64_t const *values, size_t size, void *data)

Callback to interept lower bounds.

Parameters

values	the values of the current lower bound
size	the number of values in the lower bound
data	the user data

Returns

whether the call was successful
