Detailed Description

Present a PathHandleGraph that is a backing HandleGraph but restricted to a subset of nodes.

Warning: we don't yet have a subgraph interface. So we only consider paths from the backing graph that are fully contained in the subgraph.

Constructor & Destructor Documentation

◆ PathSubgraphOverlay()

vg::PathSubgraphOverlay::PathSubgraphOverlay ( const PathHandleGraph backing,
const unordered_set< nid_t > *  node_subset 
)

Make a new PathSubgraphOverlay. The backing graph must not be modified while the overlay exists.

◆ ~PathSubgraphOverlay()

vg::PathSubgraphOverlay::~PathSubgraphOverlay ( )
virtual

Member Function Documentation

◆ for_each_path_handle_impl()

bool vg::PathSubgraphOverlay::for_each_path_handle_impl ( const std::function< bool(const path_handle_t &)> &  iteratee) const
protectedvirtual

Execute a function on each path in the graph. If it returns false, stop iteration. Returns true if we finished and false if we stopped early.

Implements handlegraph::PathHandleGraph.

◆ for_each_step_on_handle_impl()

bool vg::PathSubgraphOverlay::for_each_step_on_handle_impl ( const handle_t handle,
const std::function< bool(const step_handle_t &)> &  iteratee 
) const
protectedvirtual

Execute a function on each step of a handle in any path. If it returns false, stop iteration. Returns true if we finished and false if we stopped early.

Implements handlegraph::PathHandleGraph.

◆ get_handle_of_step()

handle_t vg::PathSubgraphOverlay::get_handle_of_step ( const step_handle_t step_handle) const
virtual

Get a node handle (node ID and orientation) from a handle to an step on a path.

Implements handlegraph::PathHandleGraph.

◆ get_is_circular()

bool vg::PathSubgraphOverlay::get_is_circular ( const path_handle_t path_handle) const
virtual

Look up whether a path is circular.

Implements handlegraph::PathHandleGraph.

◆ get_next_step()

step_handle_t vg::PathSubgraphOverlay::get_next_step ( const step_handle_t step_handle) const
virtual

Returns a handle to the next step on the path. If the given step is the final step of a non-circular path, this method has undefined behavior. In a circular path, the "last" step will loop around to the "first" step.

Implements handlegraph::PathHandleGraph.

◆ get_path_count()

size_t vg::PathSubgraphOverlay::get_path_count ( ) const
virtual

Returns the number of paths stored in the graph.

Implements handlegraph::PathHandleGraph.

◆ get_path_handle()

path_handle_t vg::PathSubgraphOverlay::get_path_handle ( const std::string &  path_name) const
virtual

Look up the path handle for the given path name. The path with that name must exist.

Implements handlegraph::PathHandleGraph.

◆ get_path_handle_of_step()

path_handle_t vg::PathSubgraphOverlay::get_path_handle_of_step ( const step_handle_t step_handle) const
virtual

Returns a handle to the path that an step is on.

Implements handlegraph::PathHandleGraph.

◆ get_path_name()

std::string vg::PathSubgraphOverlay::get_path_name ( const path_handle_t path_handle) const
virtual

Look up the name of a path from a handle to it.

Implements handlegraph::PathHandleGraph.

◆ get_previous_step()

step_handle_t vg::PathSubgraphOverlay::get_previous_step ( const step_handle_t step_handle) const
virtual

Returns a handle to the previous step on the path. If the given step is the first step of a non-circular path, this method has undefined behavior. In a circular path, it will loop around from the "first" step (i.e. the one returned by path_begin) to the "last" step.

Implements handlegraph::PathHandleGraph.

◆ get_step_count()

size_t vg::PathSubgraphOverlay::get_step_count ( const path_handle_t path_handle) const
virtual

Returns the number of node steps in the path.

Implements handlegraph::PathHandleGraph.

◆ has_next_step()

bool vg::PathSubgraphOverlay::has_next_step ( const step_handle_t step_handle) const
virtual

Returns true if the step is not the last step in a non-circular path.

Implements handlegraph::PathHandleGraph.

◆ has_path()

bool vg::PathSubgraphOverlay::has_path ( const std::string &  path_name) const
virtual

Determine if a path name exists and is legal to get a path handle for.

Implements handlegraph::PathHandleGraph.

◆ has_previous_step()

bool vg::PathSubgraphOverlay::has_previous_step ( const step_handle_t step_handle) const
virtual

Returns true if the step is not the first step in a non-circular path.

Implements handlegraph::PathHandleGraph.

◆ path_back()

step_handle_t vg::PathSubgraphOverlay::path_back ( const path_handle_t path_handle) const
virtual

Get a handle to the last step, which will be an arbitrary step in a circular path that we consider "last" based on our construction of the path. If the path is empty then the implementation must return the same value as path_front_end().

Implements handlegraph::PathHandleGraph.

◆ path_begin()

step_handle_t vg::PathSubgraphOverlay::path_begin ( const path_handle_t path_handle) const
virtual

Get a handle to the first step, which will be an arbitrary step in a circular path that we consider "first" based on our construction of the path. If the path is empty, then the implementation must return the same value as path_end().

Implements handlegraph::PathHandleGraph.

◆ path_end()

step_handle_t vg::PathSubgraphOverlay::path_end ( const path_handle_t path_handle) const
virtual

Get a handle to a fictitious position past the end of a path. This position is returned by get_next_step for the final step in a path in a non-circular path. Note: get_next_step will NEVER return this value for a circular path.

Implements handlegraph::PathHandleGraph.

◆ path_front_end()

step_handle_t vg::PathSubgraphOverlay::path_front_end ( const path_handle_t path_handle) const
virtual

Get a handle to a fictitious position before the beginning of a path. This position is return by get_previous_step for the first step in a path in a non-circular path. Note: get_previous_step will NEVER return this value for a circular path.

Implements handlegraph::PathHandleGraph.
