C# Class NVelocity.App.FieldMethodizer

This is a small utility class allow easy access to static fields in a class, such as string constants. Velocity will not introspect for class fields (and won't in the future :), but writing setter/getter methods to do this really is a pain, so use this if you really have to access fields.

The idea it so enable access to the fields just like you would in Java. For example, in Java, you would access a static field like

 MyClass.STRING_CONSTANT

and that is the same thing we are trying to allow here.

So to use in your Java code, do something like this :

 context.put("runtime", new FieldMethodizer( "NVelocity.Runtime.Runtime" ));

and then in your template, you can access any of your static fields in this way :

 $runtime.RUNTIME_LOG_WARN_STACKTRACE

Right now, this class only methodizes public static fields. It seems that anything else is too dangerous. This class is for convenience accessing 'constants'. If you have fields that aren't static it may be better to handle them by explicitly placing them into the context.

Public Methods

Method	Description
AddObject ( Object o ) : void	Add an Object to methodize
AddObject ( String s ) : void	Add the Name of the class to methodize
FieldMethodizer ( ) : System	Allow object to be initialized without any data. You would use addObject() to add data later.
FieldMethodizer ( Object o ) : System	Constructor that takes as it's arg a living object to methodize. Note that it will still only methodized the public static fields of the class.
FieldMethodizer ( String s ) : System	Constructor that takes as it's arg the name of the class to methodize.
Get ( String fieldName ) : Object	Accessor method to get the fields by name.

Private Methods

Method	Description
Inspect ( Type type ) : void	Method that retrieves all public static fields in the class we are methodizing.
