| Java APIs considerations |

| |
| Introduction |
| |
| In this part of the migration guide we address the differences of the APIs |
| in Struts Tiles and Apache Tiles\u0099. |
| |
| If you are a Tiles extension developer and you want to convert your existing |
| extension, see {{{./extension.html}Tiles extensions}} migration guide. |
| |
| Controllers and View Preparers |
| |
| In Apache Tiles\u0099, the concept of a Tiles <<<Controller>>>, i.e. an object that it is |
| invoked before rendering a definition, has been replaced with |
| <<<ViewPreparer>>>. |
| |
| The classes that implement the <<<Controller>>> interface must now implement |
| the new <<<ViewPreparer>>> interface, or extend the <<<ViewPreparerSupport>>> |
| class. |
| |
| Tiles <<<ComponentContext>>> |
| |
| The <<<ComponentContext>>>, i.e. the Tiles-specific context in which the |
| current attribute values are stored, has been renamed to |
| <<<AttributeContext>>>. |
| |
| The method <<<getAttribute>>> returns an <<Attribute>>, and not an |
| <<Attribute Value>>, i.e. a simple object. |
