de.infoasset.platform.handler
Class Station

java.lang.Object
  de.infoasset.platform.handler.Station

Direct Known Subclasses:

AnswerStation, InvisibleStation, Line

public abstract class Station
extends java.lang.Object

This class is not inteded to be directly subclassed by a concrete Station but serves as a base class to the station types that are available to the system. Currently, three different station types are available and can thus be subclassed (also have a look at the class hierarchy of Station):

• AnswerStation to send a response back to the user,
• Line to forward the request handling to some other handler, and
• InvisibleStation which does nothing.

This class provides basic infrastructure to stations. A station may carry out some additional actions which are executed in the next()method.
Currently, the following actions exist:

• sending a mail via a Mail
• performing some computations on a template via a TemplateAction

These additional actions are defined as fields within the definition of the station and will be found via reflection. To find examples of them look for subclasses of Mail and TemplateAction.

Execution order (see next()): At first all mails are executed in the order they appear in the code, then all template actions, then the actual station code (see getResponse()).
