Class TokenFactoryFactory

java.lang.Object
  org.extex.framework.AbstractFactory
      org.extex.interpreter.max.TokenFactoryFactory

All Implemented Interfaces:

Configurable, LogEnabled, RegistrarObserver, ResourceAware

public class TokenFactoryFactory
extends AbstractFactory

This class provides a factory for a TokenFactory. This factory inherits its properties from the AbstractFactory. Among them the support for configuration and logging.

Configuration

Mainly the configuration needs to specify which class to use for the TokenFactory. The name of the class is given as the argument class as shown below.

   <TokenFactory class="org.extex.scanner.type.token.TokenFactoryImpl"/>
  

The named class needs to implement the interface TokenFactory. If this interface is not implemented an error is raised.

The configuration is passed down to the new instance if it implements the interface Configurable.

If the class implements the interface LogEnabled then a logger is passed to the new instance. For this purpose the factory itself is log enabled to receive the logger.
