Package de.uni_trier.wi2.procake.utils.composition

Class CompositionManager

java.lang.Object
de.uni_trier.wi2.procake.utils.composition.CompositionManager
public class CompositionManager extends Object
The composition manager binds possible implementation of a factory to a factory. The definition is done in a XML file, defined by composition.dtd.

The factories must implement the Factoryinterface and the implementations must implement the FactoryObjectImplementation.

Usage: The usage is quite simple: 

 CompositionManager compo = new CompositionManager();
 compo.setConfigrationFile("application.comp");
 compo.build();

An example definition file looks like this: 

 <?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE Composition SYSTEM "composition.dtd">
 <Composition>
   <Factory name="data_model" class="de.uni_trier.wi2.procake.data.model.ModelFactory">
     <Implementation class="de.uni_trier.wi2.procake.data.model.impl.ModelFactoryObjectImpl">
       <Parameter value="modelName" value="default"/>
       <Parameter value="modelPath" value="/de/uni_trier/wi2/procake/model.xml"/>
     </Implementation>
   </Factory>
 </Composition>
