Classic logging Methods
Each of these methods takes an optional tag list, then a set of parameters the way a printf function does. If the log level of the instance is low enough, a log item will be created theb passed to the handlers.
Example :
logger#warning "Unexpected value: %s" (to_string my_value)method flash : 'a. ?tags:Default_handlers.tag list ->
('a, unit, string, unit) format4 ->
'amethod error : 'a. ?tags:Default_handlers.tag list ->
('a, unit, string, unit) format4 ->
'amethod warning : 'a. ?tags:Default_handlers.tag list ->
('a, unit, string, unit) format4 ->
'amethod info : 'a. ?tags:Default_handlers.tag list ->
('a, unit, string, unit) format4 ->
'amethod debug : 'a. ?tags:Default_handlers.tag list ->
('a, unit, string, unit) format4 ->
'aLazy logging methods
Each of these methods takes a string lazy_t as an input (as well as the optional tag list. If the log level of the instance is low enough, the lazy value will forced into a string, a log item will be created then passed to the handlers.
Example:
logger#ldebug (lazy (heavy_calculation () ))method ldebug : ?tags:Default_handlers.tag list -> string lazy_t -> unitmethod linfo : ?tags:Default_handlers.tag list -> string lazy_t -> unitmethod lwarning : ?tags:Default_handlers.tag list -> string lazy_t -> unitmethod lerror : ?tags:Default_handlers.tag list -> string lazy_t -> unitmethod lflash : ?tags:Default_handlers.tag list -> string lazy_t -> unitString logging methods
These methods take a simple string as input.
method sdebug : ?tags:Default_handlers.tag list -> string -> unitmethod serror : ?tags:Default_handlers.tag list -> string -> unitmethod sflash : ?tags:Default_handlers.tag list -> string -> unitmethod sinfo : ?tags:Default_handlers.tag list -> string -> unitmethod swarning : ?tags:Default_handlers.tag list -> string -> unitOther methods
method set_level : log_level -> unitSets the log level of the logger instance.
method add_handler : Default_handlers.t -> unitAdds a handler to the logger instance.
method get_handlers : Default_handlers.t listmethod effective_level : log_levelReturs this logger level if it is not None, else searches amongst ancestors for the first defined level; returns NoLevel if no level can be found.
