Detailed Description

AppenderSkeleton is a helper class, simplifying implementation of Appenders: it already takes care of handling of Thresholds and Filters.

AppenderSkeleton::AppenderSkeleton

(

const std::string &

name

)

[protected]

Member Function Documentation

virtual void AppenderSkeleton::_append

(

const LoggingEvent &

event

)

[protected, pure virtual]

Log in Appender specific way. Subclasses of Appender should implement this method to perform actual logging.

Parameters:

event

The LoggingEvent to log.

Implemented in RemoteSyslogAppender, FileAppender, SyslogAppender, IdsaAppender, StringQueueAppender, AbortAppender, RollingFileAppender, OstreamAppender, and BufferingAppender.

virtual void AppenderSkeleton::close

(

)

[pure virtual]

Release any resources allocated within the appender such as file handles, network connections, etc.

Implements Appender.

Implemented in RemoteSyslogAppender, SyslogAppender, FileAppender, IdsaAppender, StringQueueAppender, AbortAppender, OstreamAppender, and BufferingAppender.

virtual void AppenderSkeleton::doAppend

(

const LoggingEvent &

event

)

[virtual]

Log in Appender specific way.

Parameters:

event

The LoggingEvent to log.

Implements Appender.

virtual Filter* AppenderSkeleton::getFilter

(

)

[virtual]

Get the Filter for this appender.

Returns:

the filter, or NULL if no filter has been set.

Implements Appender.

virtual Priority::Value AppenderSkeleton::getThreshold

(

)

[virtual]

Get the threshold priority of this Appender.

Returns:

the threshold

Implements Appender.

AppenderSkeleton& AppenderSkeleton::operator=

(

const AppenderSkeleton &

)

[private]

virtual bool AppenderSkeleton::reopen

(

)

[virtual]

Reopens the output destination of this Appender, e.g. the logfile or TCP socket.

Returns:

false if an error occured during reopening, true otherwise.

Implements Appender.

Reimplemented in RemoteSyslogAppender, SyslogAppender, FileAppender, IdsaAppender, StringQueueAppender, AbortAppender, and OstreamAppender.

virtual bool AppenderSkeleton::requiresLayout

(

)

const [pure virtual]

Check if the appender uses a layout.

Returns:

true if the appender implementation requires a layout.

Implements Appender.

Implemented in IdsaAppender, LayoutAppender, and AbortAppender.

virtual void AppenderSkeleton::setFilter

(

Filter *

filter

)

[virtual]

Set a Filter for this appender.

Implements Appender.

virtual void AppenderSkeleton::setLayout

(

Layout *

layout

)

[pure virtual]

Set the Layout for this appender.

Parameters:

layout

The layout to use.

Implements Appender.

Implemented in IdsaAppender, AbortAppender, and LayoutAppender.

virtual void AppenderSkeleton::setThreshold

(

Priority::Value

priority

)

[virtual]

Set the threshold priority of this Appender. The Appender will not appender LoggingEvents with a priority lower than the threshold. Use Priority::NOTSET to disable threshold checking.

Parameters:

priority

The priority to set.

Implements Appender.
