Method Detail

init

public static void init(java.lang.String filename,
                        int policy)

Initialize the log by specifying a filename (or null), and also a logging policy. The logging policy is formed from the bitwise OR of one or more of the policy specifiers: LogToFile and LogToStdErr. The log file is actually appended to. Prior log informtation will be preserved. This function prints a banner to the log that contains the current date, thereby distinguishing the log data for different runs.

Write a message to the log.
