type identifier = pred_ididentifier is the type of the identifier stored in the table. It is meant to be associated with a string
This exception can be raised when some identifier or some symbol is not found in a query
val empty : tableempty is an empty table
val find_id_of_sym : string -> table -> identifierfind_id_of_sym sym t returns the identifier of the string sym stored in t. Raises Not_found if no such identifier exists.
val find_sym_from_id : identifier -> table -> stringfind_sym_from_id id t returns the string (i.e. the symbol) corresponding to the identifier id in table t
val add_sym : string -> table -> identifier * tableadd_sym sym t returns a pair (id,t') where id is the identifier associated with sym in t'. If sym already was in t then t'=t and id is the identifier which it was associated with. Otherwise, a new identifier is generated and the new association is stored in t'.
val to_string : table -> stringto_string t outputs the table t in a string.
val log_content : Logs.level -> table -> unitlog_content level t logs the content of table t.
val fold : (identifier -> string -> 'a -> 'a) -> table -> 'a -> 'afold f table a returns f id1 sym1 (f id2 sym2 ( ... ( f idN
symN a) ... )) where the (id,sym) pairs are the ones that are stored in the table table. The order of these key-value pairs in the table is unspecified.
