Detailed Description
A class that can be used to simplify a graph, by repeatedly popping leaf bubbles under a certain size. Keeps graph paths and an optional set of BED- like features up to date. TODO: doesn't handle path start and end positions within nodes.
Constructor & Destructor Documentation
◆ SmallSnarlSimplifier()
| vg::SmallSnarlSimplifier::SmallSnarlSimplifier | ( | VG & | graph | ) |
Make a simplifier that simplifies the given graph in place.
Member Function Documentation
◆ simplify()
| void vg::SmallSnarlSimplifier::simplify | ( | ) |
Simplify the graph until material stops being deleted or the maximum iteration count is reached.
◆ simplify_once()
| pair< size_t, size_t > vg::SmallSnarlSimplifier::simplify_once | ( | size_t | iteration = 0 | ) |
Simplify the graph by one step. Returns the number of nodes deleted and the number of edges deleted. Can be passed an iteration for its progress messages.
Member Data Documentation
◆ drop_hairpin_paths
| bool vg::SmallSnarlSimplifier::drop_hairpin_paths = false |
Should we simplify bubbles where paths come in and leave through the enterance node (and delete those paths) (true)? Or should we leave those bubbles unsimplified?
◆ features
| FeatureSet* vg::SmallSnarlSimplifier::features = nullptr |
If the user points this to a FeatureSet, that FeatureSet will get its features updated with changes to the graph as simplification proceeds. The user should load the features in and pull them out. TODO: Replace this with an on_path_edit event on this object that can be listened on.
◆ graph
|
protected |
Holds a reference to the graph we're simplifying.
◆ max_iterations
| size_t vg::SmallSnarlSimplifier::max_iterations = 10 |
How many iterations of simplification should we allow in a simplify() call?
◆ min_size
| size_t vg::SmallSnarlSimplifier::min_size = 10 |
What's the miniumum size of a bubble to keep, in involved bases? Everything smaller will get squished away.
◆ site_manager
|
protected |
This keeps track of the sites to simplify.
◆ traversal_finder
|
protected |
This is used to find traversals of those sites.
