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
ToolboxFactorywith 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. :)
