hook_block_build_BASE_BLOCK_ID_alter

hook_block_build_BASE_BLOCK_ID_alter(array &$build, \Drupal\Core\Block\BlockPluginInterface $block)

Provide a block plugin specific block_build alteration.

In this hook name, BASE_BLOCK_ID refers to the block implementation's plugin id, regardless of whether the plugin supports derivatives. For example, for the \Drupal\system\Plugin\Block\SystemPoweredByBlock block, this would be 'system_powered_by_block' as per that class's annotation. And for the \Drupal\system\Plugin\Block\SystemMenuBlock block, it would be 'system_menu_block' as per that class's annotation, regardless of which menu the derived block is for.

Parameters

array $build: A renderable array of data, only containing #cache.

\Drupal\Core\Block\BlockPluginInterface $block: The block plugin instance.
