Detailed Description

A HandleGraph implementation that wraps some other handle graph and hides any nodes that have no sequence associated with them.

Constructor & Destructor Documentation

◆ NullMaskingGraph() [1/2]

vg::NullMaskingGraph::NullMaskingGraph ( const HandleGraph graph)

Initialize with the graph we want to mask null nodes in.

◆ NullMaskingGraph() [2/2]

vg::NullMaskingGraph::NullMaskingGraph ( )
default

Default constructor – not actually functional.

◆ ~NullMaskingGraph()

vg::NullMaskingGraph::~NullMaskingGraph ( )
default

Default destructor.

Member Function Documentation

◆ flip()

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

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::NullMaskingGraph::for_each_handle_impl ( const function< bool(const handle_t &)> &  iteratee,
bool  parallel = false 
) const

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::NullMaskingGraph::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::NullMaskingGraph::get_id ( const handle_t handle) const
virtual

Get the ID from a handle.

Implements handlegraph::HandleGraph.

◆ get_is_reverse()

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

Get the orientation of a handle.

Implements handlegraph::HandleGraph.

◆ get_length()

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

Get the length of a node.

Implements handlegraph::HandleGraph.

◆ get_node_count()

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

Return the number of nodes in the graph.

Implements handlegraph::HandleGraph.

◆ get_sequence()

string vg::NullMaskingGraph::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_underlying_handle()

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

ExpandingOverlayGraph interface.

Returns the handle in the underlying graph that corresponds to a handle in the overlay

Implements handlegraph::ExpandingOverlayGraph.

◆ has_node()

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

HandleGraph interface.

Implements handlegraph::HandleGraph.

◆ max_node_id()

id_t vg::NullMaskingGraph::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::NullMaskingGraph::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.

Member Data Documentation

const HandleGraph* vg::NullMaskingGraph::graph = nullptr
private

The graph we're masking empty nodes in.

◆ num_null_nodes
