AccessLogFormatter

• java.lang.Object

Fields Summary
protected static final String[]	months The set of month abbreviations for log messages.
protected static final String	SPACE When formatting log lines, we often use strings like this one (" ").
protected SimpleDateFormat	dayFormatter A date formatter to format Dates into a day string in the format "dd".
protected SimpleDateFormat	monthFormatter A date formatter to format a Date into a month string in the format "MM".
protected SimpleDateFormat	yearFormatter A date formatter to format a Date into a year string in the format "yyyy".
protected SimpleDateFormat	timeFormatter A date formatter to format a Date into a time in the format "kk:mm:ss" (kk is a 24-hour representation of the hour).
protected String	timeZone The time zone relative to GMT.
protected TimeZone	tz
protected boolean	needTimeTaken
private Date	currentDate The system time when we last updated the Date that this valve uses for log lines.

Constructors Summary
public AccessLogFormatter() Constructor. Initialize the timeZone and currentDate. tz = TimeZone.getDefault(); timeZone = calculateTimeZoneOffset(tz.getRawOffset()); currentDate = new Date(System.currentTimeMillis());

Methods Summary
public abstract void	appendLogEntry(org.apache.catalina.Request request, org.apache.catalina.Response response, java.nio.CharBuffer charBuffer) Appends an access log entry line, with info obtained from the given request and response objects, to the given CharBuffer. param request The request object from which to obtain access log info param response The response object from which to obtain access log info param charBuffer The CharBuffer to which to append access log info
protected java.lang.String	calculateTimeZoneOffset(long offset) StringBuffer sb = new StringBuffer(); if ((offset<0)) { sb.append("-"); offset = -offset; } else { sb.append("+"); } long hourOffset = offset/(1000*60*60); long minuteOffset = (offset/(1000*60)) % 60; if (hourOffset<10) sb.append("0"); sb.append(hourOffset); if (minuteOffset<10) sb.append("0"); sb.append(minuteOffset); return sb.toString();
protected synchronized java.util.Date	getDate() This method returns a Date object that is accurate to within one second. If a writerThread calls this method to get a Date and it's been less than 5 second since a new Date was created, this method simply gives out the same Date again so that the system doesn't spend time creating Date objects unnecessarily. // Only create a new Date once per second, max. long systime = System.currentTimeMillis(); if ((systime - currentDate.getTime()) > 5000) { currentDate = new Date(systime); } return currentDate;
protected java.lang.String	lookup(java.lang.String month) Return the month abbreviation for the specified month, which must be a two-digit String. param month Month number ("01" .. "12"). int index; try { index = Integer.parseInt(month) - 1; } catch (Throwable t) { index = 0; // Can not happen, in theory } return (months[index]);
public boolean	needTimeTaken() Has the time-taken token been specified in the access log pattern? return true if the time-taken token has been specified in the access log pattern, false otherwise. return needTimeTaken;
