public class PatternLayout
extends PatternLayoutBase<IAccessEvent>

This class is a module-specific implementation of PatternLayout to allow http-specific patterns to be used. The ch.qos.logback.access.PatternLayout provides a way to format the logging output that is just as easy and flexible as the usual PatternLayout.

For more information about this layout, please refer to the online manual at http://logback.qos.ch/manual/layouts.html#AccessPatternLayout

Method Detail

getDefaultConverterMap

public java.util.Map<java.lang.String,java.lang.String> getDefaultConverterMap()

Returns the default converter map for this instance.

Specified by:

getDefaultConverterMap in class PatternLayoutBase<IAccessEvent>

Returns:

A map associating pattern words to the names of converter classes

doLayout

public java.lang.String doLayout(IAccessEvent event)

Description copied from interface: Layout

Transform an event (of type Object) and return it as a String after appropriate formatting.

Taking in an object and returning a String is the least sophisticated way of formatting events. However, it is remarkably CPU-effective.

Parameters:

event - The event to format

Returns:

the event formatted as a String

start

public void start()

Specified by:

start in interface LifeCycle

Overrides:

start in class PatternLayoutBase<IAccessEvent>

getPresentationHeaderPrefix

protected java.lang.String getPresentationHeaderPrefix()

Overrides:

getPresentationHeaderPrefix in class PatternLayoutBase<IAccessEvent>
