| /** |
| * Marker annotation for methods that should be executed at the start of rendering the component. This usually includes |
| * rendering of the component's start tag. |
| * <p/> |
| * Such methods may optionally take a {@link org.apache.tapestry.MarkupWriter} parameter, and may return void or |
| * boolean. Returning true or void will allow the component to advance into the render template / render body phase. If |
| * a body is present, the {@link org.apache.tapestry.annotation.BeforeRenderBody} phase will execute. If a component has |
| * a template, the {@link BeforeRenderTemplate} phase will execute (and the render body will only occur if the template |
| * directs so). |
| * <p/> |
| * Either way, the {@link org.apache.tapestry.annotation.AfterRender} phase will execute after the template and/or body |
| * have rendered. A component with a body but without a template will still see the {@link |
| * org.apache.tapestry.annotation.BeforeRenderBody} phase execute. |
| * <p/> |
| * Returning false will skip rendering of the template and/or body, and jump directly to the {@link AfterRender} phase. |
