所有已实现的接口:

Appender, AppenderAttachable, OptionHandler, UnrecognizedElementHandler

public class RewriteAppender
extends AppenderSkeleton
implements AppenderAttachable, UnrecognizedElementHandler

This appender forwards a logging request to another appender after possibly rewriting the logging event. This appender (with the appropriate policy) replaces the MapFilter, PropertyFilter and ReflectionFilter from log4j 1.3.

构造器详细资料

RewriteAppender

public RewriteAppender()

方法详细资料

append

protected void append(LoggingEvent event)

Subclasses of AppenderSkeleton should implement this method to perform actual logging. See also AppenderSkeleton.doAppend method.

指定者:

append 在类中 AppenderSkeleton

addAppender

public void addAppender(Appender newAppender)

Add appender.

指定者:

addAppender 在接口中 AppenderAttachable

参数:

newAppender - appender to add, may not be null.

getAllAppenders

public java.util.Enumeration getAllAppenders()

Get iterator over attached appenders.

指定者:

getAllAppenders 在接口中 AppenderAttachable

返回:

iterator or null if no attached appenders.

getAppender

public Appender getAppender(java.lang.String name)

Get appender by name.

指定者:

getAppender 在接口中 AppenderAttachable

参数:

name - name, may not be null.

返回:

matching appender or null.

close

public void close()

Close this AsyncAppender by interrupting the dispatcher thread which will process all pending events before exiting.

指定者:

close 在接口中 Appender

isAttached

public boolean isAttached(Appender appender)

Determines if specified appender is attached.

指定者:

isAttached 在接口中 AppenderAttachable

参数:

appender - appender.

返回:

true if attached.

requiresLayout

public boolean requiresLayout()

Configurators call this method to determine if the appender requires a layout. If this method returns true, meaning that layout is required, then the configurator will configure an layout using the configuration information at its disposal. If this method returns false, meaning that a layout is not required, then layout configuration will be skipped even if there is available layout configuration information at the disposal of the configurator..

In the rather exceptional case, where the appender implementation admits a layout but can also work without it, then the appender should return true.

指定者:

requiresLayout 在接口中 Appender

removeAllAppenders

public void removeAllAppenders()

Removes and closes all attached appenders.

指定者:

removeAllAppenders 在接口中 AppenderAttachable

removeAppender

public void removeAppender(Appender appender)

Removes an appender.

指定者:

removeAppender 在接口中 AppenderAttachable

参数:

appender - appender to remove.

removeAppender

public void removeAppender(java.lang.String name)

Remove appender by name.

指定者:

removeAppender 在接口中 AppenderAttachable

参数:

name - name.

setRewritePolicy

public void setRewritePolicy(RewritePolicy rewritePolicy)

parseUnrecognizedElement

public boolean parseUnrecognizedElement(org.w3c.dom.Element element,
                               java.util.Properties props)
                                 throws java.lang.Exception

Called to inform a configured object when an unrecognized child element is encountered.

指定者:

parseUnrecognizedElement 在接口中 UnrecognizedElementHandler

参数:

element - element, may not be null.

props - properties in force, may be null.

返回:

true if configured object recognized the element

抛出:

java.lang.Exception - throw an exception to prevent activation of the configured object.
