Examples of org.python.indexer.NBinding

org.python.indexer.NBinding
An {@code NBinding} collects information about a fully qualified name (qname)in the code graph.
Each qname has an associated {@link NType}. When a particular qname is assigned values of different types at different locations, its type is represented as a {@link NUnionType}.
Each qname has a set of one or more definitions, and a set of zero or more references. Definitions and references correspond to code locations.

            return;
        }
        NModuleType mt = qname.getType().asModuleType();


        String modQname = mt.getTable().getPath();
        NBinding mb = Indexer.idx.lookupQname(modQname);
        if (mb == null) {
            mb = Indexer.idx.moduleTable.lookup(modQname);
        }
