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. <p> 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 <blockquote><pre> MyClass.STRING_CONSTANT </pre></blockquote> and that is the same thing we are trying to allow here. <p> So to use in your Java code, do something like this : <blockquote><pre> context.put("runtime", new FieldMethodizer( "org.apache.velocity.runtime.Runtime" )); </pre></blockquote> and then in your template, you can access any of your static fields in this way : <blockquote><pre> $runtime.COUNTER_NAME </pre></blockquote> <p> Right now, this class only methodizes <code>public static</code> fields. It seems that anything else is too dangerous. This class is for convenience accessing 'constants'. If you have fields that aren't <code>static</code> it may be better to handle them by explicitly placing them into the context. <P> <P> <DL> <DT><B>Version:</B></DT> <DD>$Id: FieldMethodizer.java
