Formatter

class Formatter extends java.util.logging.Formatter

A standard log formatter for scala. This extends the java built-in log formatter.

Truncation, exception formatting, multi-line logging, and time zones are handled in this class. Subclasses are called for formatting the line prefix, formatting the date, and determining the line terminator.

Instance Constructors

  1. new Formatter(timezone: Option[String] = scala.None, truncateAt: Int = 0, truncateStackTracesAt: Int = ..., useFullPackageNames: Boolean = false, prefix: String = Formatter.DefaultPrefix)

    timezone

    Should dates in log messages be reported in a different time zone rather than local time? If set, the time zone name must be one known by the java TimeZone class.

    truncateAt

    Truncate log messages after N characters. 0 = don't truncate (the default).

    truncateStackTracesAt

    Truncate stack traces in exception logging (line count).

    useFullPackageNames

    Use full package names like "com.example.thingy" instead of just the toplevel name like "thingy"?

    prefix

    Format for the log-line prefix, if any.

    There are two positional format strings (printf-style): the name of the level being logged (for example, "ERROR") and the name of the package that's logging (for example, "jobs").

    A string in < angle brackets > will be used to format the log entry's timestamp, using java's SimpleDateFormat.

    For example, a format string of:

    "%.3s [<yyyyMMdd-HH:mm:ss.SSS>] %s: "

    will generate a log line prefix of:

    "ERR [20080315-18:39:05.033] jobs: "
