interface ContextualLinkInterface in Drupal 8

Defines a contextual link plugin.

Contextual links by default are in the module_name.links.contextual.yml file. These YAML files contain a list of contextual link plugin definitions, keyed by the plugin ID. Each definition must define a route_name and a group and might define title, options, and weight. See the getter methods on this interface for an explanation of each.
