Class TypesetterFactory

      org.extex.engine.typesetter.TypesetterFactory

public class TypesetterFactory
extends AbstractFactory

This is the factory for instances of Typesetter. 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 Typesetter. The configuration provides a mapping from a type name to the sub-configuration to be used. The name of the class is given as the argument class of the sub-configuration as shown below.

   <Typesetter default="TeX">
     <TeX class="org.extex.typesetter.impl.TypesetterImpl"
          direction="lr">
       <PageBuilder class="org.extex.typesetter.pageBuilder.impl.PageBuilderImpl"/>
       <ParagraphBuilder class="org.extex.typesetter.paragraphBuilder.texImpl.TeXParagraphBuilder">
         <Hyphenator class="org.extex.typesetter.paragraphBuilder.texImpl.TeXParagraphBuilder"/>
       </ParagraphBuilder>
       <NodeFactory class="org.extex.typesetter.type.node.factory.CachingNodeFactory"/>
     </TeX>
     <develop class="org.extex.typesetter.impl.TypesetterImpl"
            direction="lr">
       <PageBuilder class="org.extex.typesetter.pageBuilder.impl.PageBuilderImpl"/>
       <ParagraphBuilder class="org.extex.typesetter.(new JUnitCore())"/>
       <NodeFactory class="org.extex.typesetter.type.node.factory.CachingUnicodeNodeFactory"/>
     </develop>
   </Typesetter>
  

The named class need to implement the interface Typesetter. 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.
