Method totalGuarantees

src/master/quota_handler.cpp:146–156

Returns the total guaranteed resource quantities requested by all quotas in the tree. Since a role's guarantees must be greater than or equal to the sum of the guarantees of its children, we can just sum the guarantees of the top-level roles.

  // than or equal to the sum of the guarantees of its children, we can
  // just sum the guarantees of the top-level roles.
  ResourceQuantities totalGuarantees() const
  {
    ResourceQuantities result;

    // Don't include the root node because it does not have quota set.
    foreachvalue (const unique_ptr<Node>& child, root->children) {
      result += child->quota.guarantees;
    }

    return result;
  }
