These tests verify that CPOs work correctly with the default implementations - * and friend function overrides in dynamic_graph. - * - * Container: deque + deque - * - * Current Status: 196 test cases (67 TEST_CASE blocks), 1860 assertions passing - * - * CPOs tested (with available friend functions): - * - vertices(g) - Get vertex range [3 tests] - * - vertices(g, pid) - Get vertex range for partition (default single partition) [4 tests] - * - num_vertices(g) - Get vertex count [3 tests] - * - num_vertices(g, pid) - Get vertex count for partition (default single partition) [4 tests] - * - find_vertex(g, uid) - Find vertex by ID [3 tests] - * - vertex_id(g, u) - Get vertex ID from descriptor [7 tests] - * - num_edges(g) - Get total edge count [3 tests] - * - num_edges(g, u) - Get edge count for vertex (SUPPORTED with deque - random_access + sized_range) - * - num_edges(g, uid) - Get edge count by vertex ID (SUPPORTED with deque - random_access + sized_range) - * - has_edge(g) - Check if graph has any edges [3 tests] - * - edges(g, u) - Get edge range for vertex [13 tests] - * - edges(g, uid) - Get edge range by vertex ID [10 tests] - * - degree(g, u) - Get out-degree of

contains_edge(g, u, v) and contains_edge(g, uid, vid) - Check if edge exists [15 tests] - * - contains_edge(g, uid, vid) - Additional dedicated tests [13 tests] - * - vertex_value(g, u) - Access vertex value (when VV != void) [1 TEST_CASE, 5 sections] - * - edge_value(g, uv) - Access edge value (when EV != void) [1 TEST_CASE, 6 sections] - * - graph_value(g) - Access graph value (when GV != void) [1 TEST_CASE, 6 sections] - * - partition_id(g, u) - Get partition ID for vertex (default single partition) [5 tests] - * - num_partitions(g) - Get number of partitions (default 1) [4 tests] - * - source_id(g, uv) - Get source vertex ID from edge (Sourced=true) [12 tests] - * - source(g, uv) - Get source vertex descriptor from edge (Sourced=true) [12 tests] - * - * Friend functions implemented and tested: - * - vertex_value(g,u) in dynamic_graph_base (lines 1345-1348) - * - edge_value(g,uv) in dynamic_vertex_base (lines 665-676) - * - edges(g,u) in dynamic_vertex_base (lines 678-679) - * - * Note: deque uses push_back() for edge insertion, so edges appear in - * insertion order (like vector and list). - * - * Note: degree(g,u) uses the CPO default implementation with std::ranges::distance. - * - * IMPORTANT: Like vov_graph_traits (vector with random_access iterators), dod_graph_traits - * (deque with random_access iterators) DOES support num_edges(g, u) and num_edges(g, uid) - * CPO overloads because: - * - edges(g, u) returns edge_descriptor_view which provides size() for random_access iterators - * - std::deque has random_access iterators, so edge_descriptor_view IS a sized_range - * - This allows O(1) edge counting per vertex via num_edges(g, u) - * - * Key deque characteristics tested: - * - Random access iterators (like vector) - * - Stable iterators (unlike vector) - not invalidated on push_back/push_front - * - Sized range with O(1) size() operation - */ - -#include -#include -#include -#include -#include -#include -#include -
