function file_entity_entity_info_alter in File Entity (fieldable files) 7.3

Same name and namespace in other branches

1. 7 file_entity.module \file_entity_entity_info_alter()
2. 7.2 file_entity.module \file_entity_entity_info_alter()

Implements hook_entity_info_alter().

Extends the core file entity to be fieldable. The file type is used as the bundle key. File types are implemented as CTools exportables, so modules can define default file types via hook_file_default_types(), and the administrator can override the default types or add custom ones via admin/structure/file-types.

File
