logging

Type Members

1. class ConsoleHandler extends Handler

   

   Log things to the console.

2. class FileHandler extends Handler

   

   A log handler that writes log entries into a file, and rolls this file at a requested interval (hourly, daily, or weekly).

3. class Formatter extends java.util.logging.Formatter

   

   A standard log formatter for scala.

   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.

4. abstract class Handler extends java.util.logging.Handler

   

   A base log handler for scala.

   A base log handler for scala. This extends the java built-in handler and connects it with a formatter automatically.

5. type HandlerFactory = () ⇒ Handler

   

6. class LazyLogRecord extends LogRecord

   

7. class LazyLogRecordUnformatted extends LazyLogRecord

   

   A lazy LogRecord that needs formatting

8. sealed abstract class Level extends java.util.logging.Level

   

9. class LogRecord extends java.util.logging.LogRecord

   

   Wrapper around java.util.logging.LogRecord.

   Wrapper around java.util.logging.LogRecord. Should only be accessed from a single thread.

   Messages are formatted by Java's LogRecord using java.text.MessageFormat whereas this class uses a regular java.text.StringFormat

   This class takes com.twitter.logging.Logger into account when inferring the sourceMethod and sourceClass names.

10. class Logger extends AnyRef

    

    Scala wrapper for logging.

11. case class LoggerFactory(node: String = "", level: Option[Level] = None, handlers: List[HandlerFactory] = Nil, useParents: Boolean = true) extends () ⇒ Logger with Product with Serializable

    

    A factory to configure a Logger.

    A factory to configure a Logger. Note that because Loggers are global, executing this factory has side-effects.

    node

    Name of the logging node. The default ("") is the top-level logger.

    level

    Log level for this node. Leaving it None is java's secret signal to use the parent logger's level.

    handlers

    Where to send log messages.

    useParents

    Override to have log messages stop at this node. Otherwise they are passed up to parent nodes.

12. class LoggerFactoryBuilder extends AnyRef

    

    Shim for java compatibility.

    Shim for java compatibility. Make a new LoggerFactoryBuilder with LoggerFactory#newBuilder().

13. trait Logging extends AnyRef

    

    A com.twitter.app.App mixin to use for logging.

    A com.twitter.app.App mixin to use for logging. Defines flags to configure the (default) logger setup. When adding logging to a twitter-server, mix in a trait that extends Logging but overrides factories.

14. class LoggingException extends Exception

    

15. sealed abstract class Policy extends AnyRef

    

16. class QueueingHandler extends Handler

    

    Proxy handler that queues log records and publishes them in another thread to a nested handler.

    Proxy handler that queues log records and publishes them in another thread to a nested handler. Useful for when a handler may block.

17. class ScribeHandler extends Handler

    

18. class StringHandler extends Handler

    

    Mostly useful for unit tests: logging goes directly into a string buffer.

19. class SyslogFormatter extends Formatter

    

20. class SyslogHandler extends Handler

    

21. class ThrottledHandler extends Handler
