Package com.opensymphony.module.sitemesh.mapper

Class PrintableDecoratorMapper

java.lang.Object

com.opensymphony.module.sitemesh.mapper.AbstractDecoratorMapper

com.opensymphony.module.sitemesh.mapper.PrintableDecoratorMapper

All Implemented Interfaces:

DecoratorMapper

public class PrintableDecoratorMapper
extends AbstractDecoratorMapper

The PrintableDecoratorMapper is a sample DecoratorMapper that will check to see whether 'printable=true' is supplied as a request parameter and if so, use the specified decorator instead. The name of this decorator should be supplied in the decorator property.

The exact 'printable=true' request criteria can be overriden with the parameter.name and parameter.value properties.

Although this DecoratorMapper was designed for creating printable versions of a page, it can be used for much more imaginative purposes.
