function ViewsBlockBase::addContextualLinks

Converts Views block content to a renderable array with contextual links.

Parameters

string|array $output: An string|array representing the block. This will be modified to be a renderable array, containing the optional '#contextual_links' property (if there are any contextual links associated with the block).

string $block_type: The type of the block. If it's 'block' it's a regular views display, but 'exposed_filter' exist as well.
