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