Detailed Description
This class is a work node computation hook (see work_node_comp_hook), which calculates the diameter and the minimal width of the work node (variables only) and keeps it in columns ``diameter'' and ``min width''.Definition at line 42 of file diameter_hook.h.

| bool coco::wnc_hook_base::_drop_columns | ( | vdbl::standard_table & | stable | ) | [protected, inherited] |
Remove all columns, whose identifiers are stored in __managed_cols from table stable.
Definition at line 34 of file comp_hook.cc.
| bool coco::wnc_hook_base::_init_column | ( | vdbl::standard_table & | stable, | |
| const char * | colname, | |||
| const _CI & | c | |||
| ) | [inline, protected, inherited] |
Add a column of type _CI with name colname to the table stable. The column is stored in __managed_cols.

| bool coco::wnc_hook_base::_init_column | ( | vdbl::standard_table & | stable, | |
| const std::string & | colname, | |||
| const _CI & | c | |||
| ) | [inline, protected, inherited] |
Add a column of type _CI with name colname to the table stable. The column is stored in __managed_cols.
Definition at line 238 of file comp_hook.h.
| bool coco::diameter_comp_hook::drop_columns | ( | vdbl::standard_table & | stable | ) | [inline, virtual] |
Upon unregistering this hook, destroy the column ``diameter'' in the ``search info'' table.
Reimplemented from coco::wnc_hook_base.
Definition at line 83 of file diameter_hook.h.
| bool coco::diameter_comp_hook::init_columns | ( | vdbl::standard_table & | stable | ) | [inline, virtual] |
Upon registering this hook, initialize the column ``diameter'' in the ``search info'' table.
Reimplemented from coco::wnc_hook_base.
Definition at line 76 of file diameter_hook.h.
| const std::string& coco::wnc_hook_base::name | ( | ) | const [inline, inherited] |
Return the identifier string of this work node computation hook.
Definition at line 190 of file comp_hook.h.
| diameter_comp_hook* coco::diameter_comp_hook::new_copy | ( | ) | const [inline, virtual] |
| search_node_id coco::wnc_hook_base::node_id | ( | const work_node & | wn | ) | const [protected, inherited] |
This method is an accessor to the search_node_id of work_node wn.
Definition at line 43 of file comp_hook.cc.
| void coco::diameter_comp_hook::operator() | ( | const work_node & | wn, | |
| dbt_row & | dbr, | |||
| std::list< delta > * | a = NULL, |
|||
| std::list< certificate > * | b = NULL | |||
| ) | const [inline, virtual] |
The evaluation operator of this computation hook. It stores the log-volume of the work_node wn in dbt_row dbr.
Implements coco::wnc_hook_base.
Definition at line 56 of file diameter_hook.h.
| search_node_relation coco::wnc_hook_base::parent_relation | ( | const work_node & | wn | ) | const [protected, inherited] |
This method is an accessor to the search_node_relation of work_node wn.
