      • toImmutable

        public LogEvent toImmutable()
        Subclasses should implement this method to provide an immutable version.
        Specified by:
        toImmutable in interface LogEvent
        Returns:
        an immutable version of this log event
      • getContextData

        public ReadOnlyStringMap getContextData()
        Description copied from interface: LogEvent
        Returns the ReadOnlyStringMap object holding context data key-value pairs.

        Context data (also known as Mapped Diagnostic Context or MDC) is data that is set by the application to be included in all subsequent log events. The default source for context data is the ThreadContext (and properties configured on the Logger that logged the event), but users can configure a custom ContextDataInjector to inject key-value pairs from any arbitrary source.

        Specified by:
        getContextData in interface LogEvent
        Returns:
        the ReadOnlyStringMap object holding context data key-value pairs
        See Also:
        ContextDataInjector, ThreadContext

        public Instant getInstant()
        Description copied from interface: LogEvent
        Returns the Instant when the message was logged.

        Caution: if this LogEvent implementation is mutable and reused for multiple consecutive log messages, then the Instant object returned by this method is also mutable and reused. Client code should not keep a reference to the returned object but make a copy instead.

        the Instant holding Instant details for this log event

        public boolean isEndOfBatch()
        Description copied from interface: LogEvent
        Returns true if this event is the last one in a batch, false otherwise. Used by asynchronous Loggers and Appenders to signal to buffered downstream components when to flush to disk, as a more efficient alternative to the immediateFlush=true configuration.
        Specified by:
        isEndOfBatch in interface LogEvent
        Returns:
        whether this event is the last one in a batch.
      • isIncludeLocation

        public boolean isIncludeLocation()
        Description copied from interface: LogEvent
        Returns whether the source of the logging request is required downstream. Asynchronous Loggers and Appenders use this flag to determine whether to take a StackTrace snapshot or not before handing off this event to another thread.
        Specified by:
        isIncludeLocation in interface LogEvent
        Returns:
        true if the source of the logging request is required downstream, false otherwise.
        See Also:
        LogEvent.getSource()
      • setEndOfBatch

        public void setEndOfBatch​(boolean endOfBatch)
        Description copied from interface: LogEvent
        Sets whether this event is the last one in a batch. Used by asynchronous Loggers and Appenders to signal to buffered downstream components when to flush to disk, as a more efficient alternative to the immediateFlush=true configuration.
        Specified by:
        setEndOfBatch in interface LogEvent
        Parameters:
        endOfBatch - true if this event is the last one in a batch, false otherwise.
      • setIncludeLocation

        public void setIncludeLocation​(boolean locationRequired)
        Description copied from interface: LogEvent
        Sets whether the source of the logging request is required downstream. Asynchronous Loggers and Appenders use this flag to determine whether to take a StackTrace snapshot or not before handing off this event to another thread.
        Specified by:
        setIncludeLocation in interface LogEvent
        Parameters:
        locationRequired - true if the source of the logging request is required downstream, false otherwise.

        public long getNanoTime()
        Description copied from interface: LogEvent
        Returns the value of the running Java Virtual Machine's high-resolution time source when this event was created, or a dummy value if it is known that this value will not be used downstream.
        Specified by:
        getNanoTime in interface LogEvent
        Returns:
        The value of the running Java Virtual Machine's high-resolution time source when this event was created.
