Detailed Description

template<class EDGE_TYPE>
struct bdlb::TopologicalSortUtilEdgeTraits< EDGE_TYPE >

This struct represents a customization point allowing clients to supply input iterators to sort having a value_types other than a bsl::pair. Clients may specialize TopologicalSortUtilEdgeTraits to supply the following:

/// The type of the directed connection from one node to another
/// `bsl::pair<NodeType, NodeType>` and `std::pair<NodeType>` work
/// without `TopologicalSortUtilEdgeTraits` specialization.
typedef EDGE_TYPE EdgeType;
 
/// Alias describing the output values from a sort, as well as the
/// results of the `from` and `to` functions of this edge traits
/// instance.  Or in other words, the node (or node identifier) type
/// of the directed acyclic graph.
typedef user-defined NodeType;
 
/// Return a `const` reference to the "from" attribute of the
/// specified `input`.  Note that the template parameter type
/// `EDGE_TYPE` is an element in the input range to `sort`.
static const NodeType& from(const EDGE_TYPE& input);
 
/// Return a `const` reference to the "from" attribute of the
/// specified `input`.  Note that the template parameter type
/// `EDGE_TYPE` is an element in the input range to `sort`.
static const NodeType& to(const EDGE_TYPE& input)
