Function Documentation

static void gr_act_after_finish (  const gr_actions_t *  acts, const gr_match_t *  match, void *  context )  [static]

Called, after an action was finished. Increases the generation if no update was specified, so nodes after the match wil get one. Definition at line 152 of file generation.c. References ASSERT_INST, _gr_generation_t::flags, _gr_generation_t::generation, and GR_GENERATION_INC_AFTER_FINISH_FLAG. Referenced by gr_install_generations().

static void gr_act_before_finish (  const gr_actions_t *  acts, const gr_match_t *  match, void *  context )  [static]

Called, before an action was finished. Increases the generation if update was specified, so newly created thinks will get a new one. Definition at line 137 of file generation.c. References ASSERT_INST, _gr_generation_t::flags, _gr_generation_t::generation, and GR_GENERATION_INC_BEFORE_FINISH_FLAG. Referenced by gr_install_generations().

static void gr_act_match (  const gr_actions_t *  acts, const gr_match_t *  match, void *  context )  [static]

Called, after an action was matched. Sets a new generation for all matched nodes/edges if requested Definition at line 98 of file generation.c.

Referenced by gr_install_generations().

int gr_get_cur_generation (  gr_graph_t *  gr  )

Gets the current generation count. Parameters: gr  The graph. Returns: The current generation count Definition at line 206 of file generation.c.

void gr_install_generations (  gr_graph_t *  gr, gr_actions_t *  acts, gr_id_t  node_gen_attr, gr_id_t  edge_gen_attr, unsigned  flags )

Install generation tracking support. Parameters: gr  The graph. acts  The actions, iff NULL, actions will not be tracked. node_gen_attr  The attribute id for the node generation attribute. edge_gen_attr  The attribute id for the edge generation attribute. flags  A bitmask of gr_generation_flags_t containing the flags. Remarks: node_gen_attr or edge_gen_attr can be set to gr_invalid_id to disable tracking. Definition at line 162 of file generation.c.
