abstract class ResourceBase extends PluginBase implements ContainerFactoryPluginInterface, ResourceInterface (View source)

Common base class for resource plugins.

Note that this base class' implementation of the permissions() method generates a permission for every method for a resource. If your resource already has its own access control mechanism, you should opt out from this default permissions() method by overriding it.
