构造方法摘要

DailyRollingFileStreamAppender()
The default constructor does nothing.

DailyRollingFileStreamAppender(org.apache.log4j.Layout layout, String filename, String datePattern)
Instantiate a DailyRollingFileAppender and open the file designated by filename.

方法摘要

void	activateOptions() If the value of File is not null, then FileStreamAppender.setFile(java.lang.String) is called with the values of File and Append properties.
String	getDatePattern() Returns the value of the DatePattern option.
void	setDatePattern(String pattern) The DatePattern takes a string in the same format as expected by SimpleDateFormat.
protected void	subAppend(org.apache.log4j.spi.LoggingEvent event) This method differentiates DailyRollingFileAppender from its super class.

构造方法详细信息

DailyRollingFileStreamAppender

public DailyRollingFileStreamAppender()

The default constructor does nothing.

DailyRollingFileStreamAppender

public DailyRollingFileStreamAppender(org.apache.log4j.Layout layout,
                                      String filename,
                                      String datePattern)
                               throws IOException

Instantiate a DailyRollingFileAppender and open the file designated by filename. The opened filename will become the ouput destination for this appender.

抛出：

IOException

方法详细信息

setDatePattern

public void setDatePattern(String pattern)

The DatePattern takes a string in the same format as expected by SimpleDateFormat. This options determines the rollover schedule.

getDatePattern

public String getDatePattern()

Returns the value of the DatePattern option.

activateOptions

public void activateOptions()

从类 FileStreamAppender 复制的描述

If the value of File is not null, then FileStreamAppender.setFile(java.lang.String) is called with the values of File and Append properties.

指定者：

接口 org.apache.log4j.spi.OptionHandler 中的 activateOptions

覆盖：

类 FileStreamAppender 中的 activateOptions

subAppend

protected void subAppend(org.apache.log4j.spi.LoggingEvent event)

This method differentiates DailyRollingFileAppender from its super class.

Before actually logging, this method will check whether it is time to do a rollover. If it is, it will schedule the next rollover time and then rollover.

覆盖：

类 StreamAppender 中的 subAppend
