28 The strings contains an unreadable message
30 exception UniverseInconsistency of string
38 Opaque data structure you will use to store constraints
43 returns a fresh universe
46 ?uri:UriManager.uri ->
51 (* names a universe if unnamed *)
52 val name_universe: universe -> UriManager.uri -> universe
55 really useful at the begin and in all the functions that don't care
58 val empty_ugraph: universe_graph
61 These are the real functions to add eq/ge/gt constraints
62 to the passed graph, returning an updated graph or raising
66 ?fast:bool -> universe -> universe -> universe_graph -> universe_graph
68 ?fast:bool -> universe -> universe -> universe_graph -> universe_graph
70 ?fast:bool -> universe -> universe -> universe_graph -> universe_graph
73 debug function to print the graph to standard error
76 universe_graph -> unit
79 does what expected, but I don't remember why this was exported
81 val string_of_universe:
85 given the list of visible universes (see universes_of_obj) returns a
86 cleaned graph (cleaned from the not visible nodes)
89 universe_graph -> universe list -> universe_graph
92 Since fresh() can't add the right uri to each node, you
93 must fill empty nodes with the uri before you serialize the graph to xml
95 these empty nodes are also filled in the universe list
97 val fill_empty_nodes_with_uri:
98 universe_graph -> universe list -> UriManager.uri ->
99 universe_graph * universe list
104 - remember already merged uri so that we completely skip already merged
105 graphs, this may include a dependecy graph (not merge a subpart of an
106 already merged graph)
109 universe_graph -> universe_graph -> universe_graph
112 ugraph to xml file and viceversa
114 val write_xml_of_ugraph:
115 string -> universe_graph -> universe list -> unit
118 given a filename parses the xml and returns the data structure
120 val ugraph_and_univlist_of_xml:
121 string -> universe_graph * universe list
122 val restart_numbering:
126 returns the universe number (used to save it do xml)
128 val univno: universe -> int
130 (** re-hash-cons URIs contained in the given universe so that phisicaly
131 * equality could be enforced. Mainly used by
132 * CicEnvironment.restore_from_channel *)
133 val recons_graph: universe_graph -> universe_graph
135 (** re-hash-cons a single universe *)
136 val recons_univ: universe -> universe
138 (** consistency chek that should be done before committin the graph to the
140 val assert_univs_have_uri: universe_graph -> universe list-> unit
142 (** asserts the universe is named *)
143 val assert_univ: universe -> unit
