    • Method Detail

      • setOutputStream

        public void setOutputStream​(OutputStream outputStream)
        Set the output stream to write to. The output stream will then belong to this handler; when the handler is closed or a new writer or output stream is set, this output stream will be closed.
        Overrides:
        setOutputStream in class OutputStreamHandler
        Parameters:
        outputStream - the new output stream or null for none

      • isRotateOnBoot

        public boolean isRotateOnBoot()
        Indicates whether or a not the handler should rotate the file before the first log record is written.
        Returns:
        true if file should rotate on boot, otherwise false/

      • setRotateOnBoot

        public void setRotateOnBoot​(boolean rotateOnBoot)
        Set to a value of true if the file should be rotated before the a new file is set. The rotation only happens if the file names are the same and the file has a length greater than 0.
        Parameters:
        rotateOnBoot - true to rotate on boot, otherwise false

      • setRotateSize

        public void setRotateSize​(long rotateSize)
        Set the rotation size, in bytes.
        Parameters:
        rotateSize - the number of bytes before the log is rotated

      • setMaxBackupIndex

        public void setMaxBackupIndex​(int maxBackupIndex)
        Set the maximum backup index (the number of log files to keep around).
        Parameters:
        maxBackupIndex - the maximum backup index

      • getSuffix

        public String getSuffix()
        Returns the suffix set to be appended to files during rotation.
        Returns:
        the suffix or null if no suffix should be used

      • setSuffix

        public void setSuffix​(String suffix)
        Sets the suffix to be appended to the file name during the file rotation. The suffix does not play a role in determining when the file should be rotated.

        The suffix must be a string understood by the SimpleDateFormat. Optionally the suffix can end with .gz or .zip which will compress the file on rotation.

        If the suffix ends with .gz or .zip the file will be compressed on rotation.

        Note: The maxBackupIndex only takes into account files rotated with same suffix. For example if the suffix pattern is .yyyy-MM-dd and the size rotation is reached only files with the same date suffix will be purged. A file the day before or after will not be purged.

        Parameters:
        suffix - the suffix to place after the filename when the file is rotated

      • preWrite

        protected void preWrite​(ExtLogRecord record)
        Execute any pre-write policy, such as file rotation. The write lock is held during this method, so make it quick. The default implementation does nothing.
        Overrides:
        preWrite in class WriterHandler
        Parameters:
        record - the record about to be logged
