Detailed Description

A HandleGraph implementation that represents a subgraph of another HandleGraph, defined by a Path. The leading and trailing nodes are cut according to the Path. Supports translation of other Paths from this graph into the base graph.

Nodes are numbered 1 to n along the path; multiple visits on the path to the same backing node will become distinct.

Constructor & Destructor Documentation

◆ PathSubgraph()

vg::PathSubgraph::PathSubgraph ( const HandleGraph base,
const Path path 
)

Create a PathSubgraph describing the subgraph of the given graph defined by the given path. The path must not be empty. The path can take part of the start and end nodes, but all mappings must be perfect matches, and all adjacent mappings must properly cross a real edge.

Member Function Documentation

◆ flip()

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

Loop over all the handles to next/previous (right/left) nodes. Passes them to a callback which returns false to stop iterating and true to continue. Returns true if we finished and false if we stopped early.

◆ for_each_handle_impl()

bool vg::PathSubgraph::for_each_handle_impl ( const 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.

◆ get_handle()

handle_t vg::PathSubgraph::get_handle ( const id_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()

id_t vg::PathSubgraph::get_id ( const handle_t handle) const
virtual

Get the ID from a handle.

Implements handlegraph::HandleGraph.

◆ get_is_reverse()

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

Get the orientation of a handle.

Implements handlegraph::HandleGraph.

◆ get_length()

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

Get the length of a node.

Implements handlegraph::HandleGraph.

◆ get_node_count()

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

Return the number of nodes in the graph.

Implements handlegraph::HandleGraph.

◆ get_sequence()

string vg::PathSubgraph::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.

◆ get_topological_order()

vector< handle_t > vg::PathSubgraph::get_topological_order ( ) const

Get a topological order very easily, since the path defines one.

◆ get_underlying_handle()

handle_t vg::PathSubgraph::get_underlying_handle ( const handle_t handle) const
virtual

ExpandingOverlayGraph interface.

Get the handle in the backing graph that the given handle in this graph represents.

Implements handlegraph::ExpandingOverlayGraph.

◆ has_node()

bool vg::PathSubgraph::has_node ( id_t  node_id) const
virtual

HandleGraph interface.

Method to check if a node exists by ID

Implements handlegraph::HandleGraph.

◆ max_node_id()

id_t vg::PathSubgraph::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()

id_t vg::PathSubgraph::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.

◆ translate_down()

Path vg::PathSubgraph::translate_down ( const Path path_against_subgraph) const

Additional Interface.

Translate a Path against us to a Path against the base graph
