Parameters:

name	The name of the Appender to return.

Returns:

a pointer to an existing Appender, or NULL if no appender with the specified name exists.

virtual Filter* Appender::getFilter

(

)

[pure virtual]

Returns:

the name of the appender.

Definition at line 109 of file Appender.hh.

virtual Priority::Value Appender::getThreshold

(

)

[pure virtual]

Get the threshold priority of this Appender.

Returns:

the threshold

Implemented in AppenderSkeleton.

Appender& Appender::operator=

(

const Appender &

)

[private]

virtual bool Appender::reopen

(

)

[pure virtual]

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

Returns:

false if an error occurred during reopening, true otherwise.

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

static bool Appender::reopenAll

(

)

[static]

Call reopen() on all existing Appenders.

Returns:

true if all Appenders returned true on their reopen() call.

virtual bool Appender::requiresLayout

(

)

const [pure virtual]

Check if the appender uses a layout.

Returns:

true if the appender implementation requires a layout.

Implemented in AppenderSkeleton, IdsaAppender, LayoutAppender, and AbortAppender.

virtual void Appender::setFilter

(

Filter *

)

[pure virtual]

Set a Filter for this appender.

Implemented in AppenderSkeleton.

virtual void Appender::setLayout

(

Layout *

layout

)

[pure virtual]

Set the Layout for this appender.

Parameters:

layout

The layout to use.

Implemented in AppenderSkeleton, IdsaAppender, AbortAppender, and LayoutAppender.

virtual void Appender::setThreshold

(

Priority::Value

priority

)

[pure 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.

Implemented in AppenderSkeleton.
