Method new()

Usage

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

Arguments

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

see rotor::rotate_date() for the meaning of these arguments. Note that fmt corresponds to format (because ⁠$format⁠ has a special meaning for R6 classes).

Usage

AppenderFileRotatingDate$clone(deep = FALSE)

Arguments
