Active bindings

cache_backups

TRUE or FALSE. If TRUE (the default) the list of backups is cached, if FALSE it is read from disk every time this appender triggers. Caching brings a significant speedup for checking whether to rotate or not based on the age of the last backup, but is only safe if there are no other programs/functions (except this appender) interacting with the backups.

Methods

Inherited methods

Method new()

Usage

AppenderFileRotatingTime$new(
  file,
  threshold = NA_integer_,
  layout = LayoutFormat$new(),
  filters = NULL,
  age = Inf,
  size = -1,
  max_backups = Inf,
  compression = FALSE,
  backup_dir = dirname(file),
  fmt = "%Y-%m-%d--%H-%M-%S",
  overwrite = FALSE,
  cache_backups = TRUE,
  create_file = NULL
)

Arguments

size, age, max_backups, compression, backup_dir, fmt, overwrite, cache_backups

see rotor::rotate_time() for the meaning of these arguments. Note that fmt corresponds to format and backup_dir to dir.
