# Map Build Process
|
|
|
|
The parts to build a map - layers, behaviors, maps, and styles - are loaded
|
|
with menu loaders, like `openlayers_layer_export_load`. They should not be
|
|
loaded manually because menu loaders do the necessary instantiation and
|
|
cache-clearing.
|
|
|
|
In 2.x, layers, behaviors, and styles contain more logic for 'rendering
|
|
themselves' than before, but cannot completely exist on their own. The functions
|
|
that iterate over included layers, behaviors, and styles are in
|
|
`openlayers.render.inc`.
|
|
|
|
`openlayers_build_map` and `openlayers_render_map` are the two essential parts
|
|
of the actual map building and rendering, and are included in
|
|
`openlayers.module`.
|
|
|
|
The map building process does not directly deal with map data: in the case that
|
|
Drupal is rendering data (as in openlayers_views), this functionality is
|
|
encapsulated in the `render()` method of the layer type. See
|
|
`modules/openlayers_views` for an example of how this works.
