Typedef Documentation

typedef enum _gr_generation_flags_t gr_generation_flags_t

Generation control flags.

typedef struct _gr_generation_t gr_generation_t

The generation type.

Enumeration Type Documentation

enum _gr_generation_flags_t

Generation control flags. Enumeration values: GR_GENERATION_INC_ON_MATCH_FLAG  generations are automatically increased on matches GR_GENERATION_UPD_ON_MATCH_FLAG  generations are automatically updated on matches GR_GENERATION_INC_BEFORE_FINISH_FLAG  generations are automatically increased before an action finished GR_GENERATION_INC_AFTER_FINISH_FLAG  generations are automatically increased after an action finish GR_GENERATION_DEFAULT_FLAGS  Definition at line 41 of file generation.h.

Function Documentation

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. References ASSERT_GR, ASSERT_INST, and _gr_generation_t::generation. Referenced by gr_graph_add_edge(), gr_graph_add_node(), and gr_graph_set_node_type().

int gr_get_next_generation (  gr_graph_t *  gr  )

Gets the next generation count. Can be used to increase the generation manualy. Parameters: gr  The graph. Returns: The next generation count Definition at line 214 of file generation.c. References ASSERT_GR, ASSERT_INST, and _gr_generation_t::generation.

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.

void gr_set_cur_generation (  gr_graph_t *  gr, int  count )

Sets the current generation count. Parameters: gr  The graph. count  The next generation count. Definition at line 222 of file generation.c. References ASSERT_GR, ASSERT_INST, and _gr_generation_t::generation.
