- the class GraphExplorer allows to explore webgraphs using the JShell
- the class Graph holds all webgraph-related data as memory-mapped data:
the graph, its transpose and the map to translate between vertex labels
and IDs. It provides methods to access successors and predecessors, etc.
- the script graph_explore_download_webgraph.sh downloads all files
required for exploring a graph
- the script graph_explore_build_vertex_map.sh builds a map of vertex
labels to vertex ID and verifies that all graph files required for
graph exploration are downloaded.
- utility methods
- get a common subset (intersection) or the union
of the successors or predecessors of a list of vertices
- class CountingMergedIntIterator to count occurrences of integers
given a list of int iterators as input
- print list of vertices
- load and save vertex lists from/to files
- count top-level domains in lists of vertices
- JShell script to load a graph
- tutorial / quick start graph exploration
