Detailed Description

Simplification of a NetGraph that ignores chains. It is designed only for traversal finding. Todo: generalize NestedFlowCaller to the point where we can remove this and use NetGraph instead

◆ SnarlGraph()

vg::SnarlGraph::SnarlGraph ( const HandleGraph backing_graph,
SnarlManager snarl_manager,
vector< const Snarl * >  snarls 
)

Member Function Documentation

◆ edge_to_snarl_edge()

tuple< bool, handle_t, edge_t > vg::SnarlGraph::edge_to_snarl_edge ( edge_t  edge) const

◆ embed_ref_path_snarls()

void vg::SnarlGraph::embed_ref_path_snarls ( SnarlTraversal traversal)

◆ embed_snarl()

void vg::SnarlGraph::embed_snarl ( Visit visit)

◆ embed_snarls()

void vg::SnarlGraph::embed_snarls ( SnarlTraversal traversal)

◆ flip()

handle_t vg::SnarlGraph::flip ( const handle_t handle) const
virtual

Invert the orientation of a handle (potentially without getting its ID)

Implements handlegraph::HandleGraph.

◆ follow_edges_impl()

bool vg::SnarlGraph::follow_edges_impl ( const handle_t handle,
bool  go_left,
const std::function< bool(const handle_t &)> &  iteratee 
) const
protectedvirtual

this is the only function that's changed to do anything different from the backing graph: it is changed to "pass through" snarls by pretending there are edges from into snarl starts out of ends and vice versa.

Implements handlegraph::HandleGraph.

◆ for_each_handle_impl()

bool vg::SnarlGraph::for_each_handle_impl ( const std::function< bool(const handle_t &)> &  iteratee,
bool  parallel = false 
) const
protectedvirtual

Loop over all the nodes in the graph in their local forward orientations, in their internal stored order. Stop if the iteratee returns false. Can be told to run in parallel, in which case stopping after a false return value is on a best-effort basis and iteration order is not defined. Returns true if we finished and false if we stopped early.

Implements handlegraph::HandleGraph.

◆ get_handle()

handle_t vg::SnarlGraph::get_handle ( const nid_t node_id,
bool  is_reverse = false 
) const
virtual

Look up the handle for the node with the given ID in the given orientation.

Implements handlegraph::HandleGraph.

◆ get_id()

nid_t vg::SnarlGraph::get_id ( const handle_t handle) const
virtual

Get the ID from a handle.

Implements handlegraph::HandleGraph.

◆ get_is_reverse()

bool vg::SnarlGraph::get_is_reverse ( const handle_t handle) const
virtual

Get the orientation of a handle.

Implements handlegraph::HandleGraph.

◆ get_length()

size_t vg::SnarlGraph::get_length ( const handle_t handle) const
virtual

Get the length of a node.

Implements handlegraph::HandleGraph.

◆ get_node_count()

size_t vg::SnarlGraph::get_node_count ( ) const
virtual

Return the number of nodes in the graph.

Implements handlegraph::HandleGraph.

◆ get_sequence()

std::string vg::SnarlGraph::get_sequence ( const handle_t handle) const
virtual

Get the sequence of a node, presented in the handle's local forward orientation.

Implements handlegraph::HandleGraph.

◆ has_node()

bool vg::SnarlGraph::has_node ( nid_t  node_id) const
virtual

Method to check if a node exists by ID.

Implements handlegraph::HandleGraph.

◆ max_node_id()

nid_t vg::SnarlGraph::max_node_id ( ) const
virtual

Return the largest ID in the graph, or some larger number if the largest ID is unavailable. Return value is unspecified if the graph is empty.

Implements handlegraph::HandleGraph.

◆ min_node_id()

nid_t vg::SnarlGraph::min_node_id ( ) const
virtual

Return the smallest ID in the graph, or some smaller number if the smallest ID is unavailable. Return value is unspecified if the graph is empty.

Implements handlegraph::HandleGraph.

◆ node_to_snarl()

pair< bool, handle_t > vg::SnarlGraph::node_to_snarl ( handle_t  handle) const
