|

* Overview of the Views module API
|
||
*
|
||
* The Views module is a generalized query and display engine, which can be used
|
||
* to make views (formatted lists, grids, feeds, and other output) of items
|
||
* (often entities, but can be other types of data). Developers can interact
|
||
* with Views in several ways:
|
||
* - Provide plugins: Views plugins govern nearly every aspect of views,
|
||
* including querying (sorting, filtering, etc.) and display (at several
|
||
* levels of granularity, ranging from the entire view to the details of a
|
||
* field). See the @link views_plugins Views plugins topic @endlink for
|
||
* more information.
|
||
* - Provide data: Data types can be provided to Views by implementing
|
||
* hook_views_data(), and data types provided by other modules can be
|
||
* altered by implementing hook_views_data_alter().
|
||
* - Implement hooks: A few operations in Views can be influenced by hooks.
|
||
* See the @link Views hooks topic @endlink for a list.
|
||
* - Theming: See the @link views_templates Views templates topic @endlink
|
||
* for more information.
