Examples of java.util.logging.StreamHandler.publish()

java.util.logging.StreamHandler.publish()
Format and publish a LogRecord.
The StreamHandler first checks if there is an OutputStream and if the given LogRecord has at least the required log level. If not it silently returns. If so, it calls any associated Filter to check if the record should be published. If so, it calls its Formatter to format the record and then writes the result to the current output stream.
If this is the first LogRecord to be written to a given OutputStream, the Formatter's "head" string is written to the stream before the LogRecord is written. @param record description of the log event. A null record issilently ignored and is not published
