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="logger" class="cake.logger.LoggerFactory">
     <Implementation class="cake.logger.log4j_1_2_8.Log4JLogger">
       <Parameter value="config" name="resources/jrelogger.conf"/>
     </Implementation>
   </Factory>
   <Factory name="util_multilanguag" class="cake.utils.multilanguage.MessageFormatterFactory">
     <Implementation class="cake.utils.multilanguage.jdk1_4.MessageFormatter">
       <Parameter value="locale" name="de"/>
     </Implementation>
   </Factory>
 </Composition>

Method Detail

build

public CakeInstanceCache build()

Returns:

A cache containing the built factories and the implementations

build

public CakeInstanceCache build(FactoryConfiguration configuration)

Builds the system. The given configuration is used to assign the specified implementations to the factories.

Parameters:

configuration - The build configuration.

Returns:

A cache containing the built factories and the implementations

setConfigurationSource

public void setConfigurationSource(InputSource configurationSource)

Parameters:

configurationSource - The configuration file that is necessary for build().

setConfigurationFile

public void setConfigurationFile(String pathComposition)
