  +--jp.ne.dti.lares.foozy.pagemixer.servlet.ProducerFactory

public class ProducerFactory

extends java.lang.Object

Factory to create "Producer" factory.

With PageServlet(or derived classes from it), this provides customization point to create Producer.Factory in your specific way.

So, this class should be named as "ProducerFactoryFactory", in fact.

This implementation requires servlet 'init-param's shown below (see setup(HttpServlet) for detail):

producer.parser.pageState(optional):

name of class implementing interface PageState to create PageParser.

Since:

PageMixer 3.0

Method Detail

setup

public Producer.Factory setup(javax.servlet.http.HttpServlet servlet)
                       throws javax.servlet.ServletException

Initialize and create "Producer" factory.

This method provides chance of specific initialization. For example:

• get servlet init-param
• get web application(= context) init-param
• allocate specific resource(e.g.: JDBC Connection, new thread)
• store information into ServletContext
• and so on

This is invoked from PageServlet.init().

This implementation looks servlet init-param up named as "producer.parser.pageState", and create PageState from it. Otherwise, this creates LoosePageState.

Then, this create PageParser, with above PageState, as Producer.Factory, and returns it

Parameters:

servlet - with which this object works

Throws:

javax.servlet.ServletException - if initialization fails

See Also:

cleanup(HttpServlet)

cleanup

public void cleanup(javax.servlet.http.HttpServlet servlet)

You should release all resources which you allocate in setup(HttpServlet) in this method.

This is invoked from PageServlet.destroy().

This implementation does nothing

Parameters:

servlet - with which this object works
