Завершающая и нетерминирующая ссылка ссылка на аполлон?

const httpLink = ...

const errorLink = ...

const link = ApolloLink.from([errorLink, httpLink]);

When doing so, be careful to chain the control flow in the correct order. The apollo-link-http is called a terminating link because it turns an operation into a result that usually occurs from a network request. On the other side, the apollo-link-error is a non-terminating link. It only enhances your terminating link with features, since a terminating link has to be last entity in the control flow chain.

Так вот, я не понял разницы между терминирующей ссылкой и неконечной ссылкой??
