class ContentModerationState in Drupal 10

Defines the Content moderation state entity.

@ContentEntityType( id = "content_moderation_state", label = @Translation("Content moderation state"), label_singular = @Translation("content moderation state"), label_plural = @Translation("content moderation states"), label_count = @PluralTranslation( singular = "@count content moderation state", plural = "@count content moderation states" ), handlers = { "storage_schema" = "Drupal\content_moderation\ContentModerationStateStorageSchema", "views_data" = "\Drupal\views\EntityViewsData", "access" = "Drupal\content_moderation\ContentModerationStateAccessControlHandler", }, base_table = "content_moderation_state", revision_table = "content_moderation_state_revision", data_table = "content_moderation_state_field_data", revision_data_table = "content_moderation_state_field_revision", translatable = TRUE, internal = TRUE, entity_keys = { "id" = "id", "revision" = "revision_id", "uuid" = "uuid", "uid" = "uid", "owner" = "uid", "langcode" = "langcode", } )

@internal This entity is marked internal because it should not be used directly to alter the moderation state of an entity. Instead, the computed moderation_state field should be set on the entity directly.
