class Robot

Defines the robot entity.

The lines below, starting with '@ConfigEntityType,' are a plugin annotation. These define the entity type to the entity type manager.

The properties in the annotation are as follows:

• id: The machine name of the entity type.
• label: The human-readable label of the entity type. We pass this through the "@Translation" wrapper so that the multilingual system may translate it in the user interface.
• handlers: An array of entity handler classes, keyed by handler type.
  • access: The class that is used for access checks.
  • list_builder: The class that provides listings of the entity.
  • form: An array of entity form classes keyed by their operation.
• entity_keys: Specifies the class properties in which unique keys are stored for this entity type. Unique keys are properties which you know will be unique, and which the entity manager can use as unique in database queries.
• links: entity URL definitions. These are mostly used for Field UI. Arbitrary keys can set here. For example, User sets cancel-form, while Node uses delete-form.
