The print()
method for Loggers displays the most important aspects of
the Logger.
You can also print just the ancestry
of a Logger which can be accessed with
with logger$ancestry()
. This returns a named character
vector whose
names correspond to the names of the Loggers logger
inherits from. The
TRUE
/FALSE
status of its elements correspond to the propagate
values of
these Loggers.
Usage
# S3 method for class 'Logger'
print(x, color = requireNamespace("crayon", quietly = TRUE), ...)
# S3 method for class 'Logger'
format(x, color = FALSE, ...)
# S3 method for class 'ancestry'
print(x, color = requireNamespace("crayon", quietly = TRUE), ...)
# S3 method for class 'ancestry'
format(x, color = FALSE, ...)
Examples
# print most important details of logger
print(lgr)
#> <LoggerRoot> [info] root
#>
#> appenders:
#> console: <AppenderConsole> [all] -> console
# print only the ancestry of a logger
lg <- get_logger("AegonV/Aerys/Rheagar/Aegon")
get_logger("AegonV/Aerys/Rheagar")$set_propagate(FALSE)
print(lg$ancestry)
#> AegonV/Aerys/Rheagar/Aegon
unclass(lg$ancestry)
#> AegonV Aerys Rheagar Aegon
#> TRUE TRUE FALSE TRUE
