Class type
Name of the logger:
val mutable level : level
Value used to filter log messages.
val parent : logger option
The optional parent of this logger.
Whether messages passed to this logger are propagated to its ancestors' handlers.
The list of functions used for dynamic tagging of messages.
method set_level : level -> unit
Sets the log level of the logger instance.
Will add a tag to each log message, resulting from the call of the supplied fonction (called each time a message is logged)
Sets the propagate attribute, which decides whether messages passed to this logger are propagated to its ancestors' handlers.
Returns the list of handlers of the logger, recursing with parents handlers if propagate is true
method effective_level : level
Returns 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.
method internal_level : level
Returns the logger internal level.
Each of these methods takes an optional string list
of tags, 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:string list -> ('a, unit, string, unit) format4 -> 'a
method error : 'a. ?tags:string list -> ('a, unit, string, unit) format4 -> 'a
method warning : 'a. ?tags:string list ->
('a, unit, string, unit) format4 ->
'a
method info : 'a. ?tags:string list -> ('a, unit, string, unit) format4 -> 'a
method trace : 'a. ?tags:string list -> ('a, unit, string, unit) format4 -> 'a
method debug : 'a. ?tags:string list -> ('a, unit, string, unit) format4 -> 'a
Each of these methods takes a string lazy_t
as an input (as well as the optional tags. 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 () ))
Each of these methods takes a string
as an input (as well as the optional tags).
Example:
logger#sdebug string_variable
