raised when something goes wrong in to_string or of_string. The integer argument is, in the case of of_string, the position in the string at which the error occurred. It has no meaning in to_string, and may take any value.
val of_string : string -> Ldap_types.filterturn the string representation into the internal representation defined in ldap_types.ml. This representation is suitable for sending on the wire, and can also have all sorts of operations performed on it. play around with it in the toplevel to get a feel for it
val to_string : Ldap_types.filter -> stringturn an internal representaion of a filter into a string representaion compliant with rfc2254
escape a string which is intended to be the VALUE of an attribute assertion in a filter. Do not use this on a whole filter, it will destroy all the meta chars. Use it only on the VALUE part of the assertion. It is NOT necessary to use this function if you intend to call to_string, escaping will be done for you in that case. This function is exposed because you may want to manipulate a filter with a regular expression, or other string means, and you may find it necessary to escape values manually in that case.
