Class EasyFactoryConfiguration

All Implemented Interfaces:
Comparable<Configuration>

public class EasyFactoryConfiguration extends FactoryConfiguration

FactoryConfiguration subclass that simplifies the process of configuring a ToolboxFactory in Java without the use of an xml or properties configuration file. Below is an example:


 EasyFactoryConfiguration config = new EasyFactoryConfiguration();
 config.toolbox(Scope.REQUEST).property("locale", Locale.US)
  .tool(DateTool.class)
  .tool("myTool", MyTool.class);
 config.toolbox(Scope.APPLICATION)
  .tool(NumberTool.class).property("locale", Locale.FR);
 ToolboxFactory factory = config.createFactory();
 

Doing the above without this class would require the following to create an equivalent FactoryConfiguration in Java:


 FactoryConfiguration factoryConfig = new FactoryConfiguration();
 ToolboxConfiguration toolbox = new ToolboxConfiguration();
 toolbox.setScope(Scope.REQUEST);
 toolbox.setProperty("locale", Locale.US);
 ToolConfiguration tool = new ToolConfiguration();
 tool.setClassname(DateTool.class.getName());
 tool = new ToolConfiguration();
 tool.setKey("myTool");
 tool.setClassname(MyTool.class.getName());
 toolbox.addTool(tool);
 toolbox = new ToolboxConfiguration();
 toolbox.setScope(Scope.APPLICATION);
 tool = new ToolConfiguration();
 tool.setClassname(NumberTool.class.getName());
 tool.setProperty("locale", Locale.FR);
 toolbox.addTool(tool);
 factoryConfig.addToolbox(toolbox);
 ToolboxFactory factory = factoryConfig.createFactory();
 

Of course, you could directly configure a ToolboxFactory with relatively little effort as well:


 ToolboxFactory factory = new ToolboxFactory();
 factory.putProperty(Scope.REQUEST, "locale", Locale.US);
 factory.addToolInfo(Scope.REQUEST, new ToolInfo("date", DateTool.class));
 factory.addToolInfo(Scope.REQUEST, new ToolInfo("render", ViewRenderTool.class));
 ToolInfo info = new ToolInfo("number", NumberTool.class);
 info.setProperty("locale", Locale.FR);
 factory.addToolInfo(Scope.APPLICATION, info);
 
But this is not reusable. Why does that matter? Well, it doesn't matter for application developers. But, if another framework wishes to provide a common VelocityTools configuration for application developers, this may come in handy. Or it may not. In any case, it was mildly fun to write. :)
