| * |
| * Indexed Relations. Imagine a really simple table in a |
| * database. Relations are not ordered. This data type is meant for |
| * maintaining a N-way mapping. |
| * |
| * g_relation_new() creates a relation with FIELDS fields |
| * |
| * g_relation_destroy() frees all resources |
| * g_tuples_destroy() frees the result of g_relation_select() |
| * |
| * g_relation_index() indexes relation FIELD with the provided |
| * equality and hash functions. this must be done before any |
| * calls to insert are made. |
| * |
| * g_relation_insert() inserts a new tuple. you are expected to |
| * provide the right number of fields. |
| * |
| * g_relation_delete() deletes all relations with KEY in FIELD |
| * g_relation_select() returns ... |
| * g_relation_count() counts ... |
