public class: ParameterDecoratorMapper [javadoc | source]

All Implemented Interfaces:

The ParameterDecoratorMapper will map a suitable decorator based on request parameters.

The ParameterDecoratorMapper is configured via three properties. decorator.parameter - the parameter which contains the name of the decorator which will be mapped. The default is "decorator".

For example if decorator.parameter is "foobar" then myurl.jsp?foobar=mydecorator will map to the decorator named "mydecorator".

You can also supply an optional 'confirmation parameter'. The decorator will only be mapped if the parameter named parameter.name is in the request URI and the value of that parameter is equal to the parameter.value property.

For example assuming parameter.name=confirm and parameter.value=true the URI myurl.jsp?decorator=mydecorator&confirm=true will map the decorator mydecorator. where as the URIs myurl.jsp?decorator=mydecorator and myurl.jsp?decorator=mydecorator&confirm=false will not return any decorator.
