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( "org.apache.velocity.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.
