Class ServerComponentFactory

  +--server.ServerComponentFactory

public class ServerComponentFactory

extends Object

This class only has one responsibility and that is to generate the necessary components for the server and then pass them a CreatesConnection so that they can connect. It is made a singleton to ensure that duplicate sets of components are never unknowingly dispatched to connect (even though this may be checked for on server side as well). The server does not have any knowledge of how to create the components and thus must rely on this class to generate them in the manner that it was compiled to. Component class types are passed into the generate command, which in turn looks up the rule on how to create that type of component and then does so. The reason that rules must be defined is because components may in fact be located on other system, and creating them could require more than just calling "new ComponentType"

Method Detail

instance

public static server.ServerComponentFactory instance()

Returns the singleton instance of this factory.

generateComponents

public void generateComponents(connect.CreatesConnection serverConnection,
                               Class[] componentTypes)

This method should create all the components necessary specified by the server. If a component type is specified that no rule has been defined for, throw an error.

getNextPort

protected int getNextPort()

Returns the next available port.

generateRules

protected HashMap generateRules()

This method should generate the map that connects class types for rules on how to create them.
