          #   Required. Resource name of the project under which the tenant is created.

          #   "projects/foo".

          #   The maximum number of resources contained in the underlying API
          #   response. If page streaming is performed per-resource, this
          #   parameter does not affect the return value. If page streaming is
          #   performed per-page, this determines the maximum number of
          #   resources in a page.
          # @param options [Google::Gax::CallOptions]
          #   Overrides the default settings for this call, e.g, timeout,
          #   retries, etc.
          # @yield [result, operation] Access the result along with the RPC operation

          #   An enumerable of Google::Cloud::Talent::V4beta1::Tenant instances.
          #   See Google::Gax::PagedEnumerable documentation for other
          #   operations such as per-page iteration or access to the response
          #   object.
          # @raise [Google::Gax::GaxError] if the RPC is aborted.
