Sawyer::Container::GraphHashIndex< VertexOrEdgeKey, VertexOrEdgeConstIterator > Class Template Reference

Description

template<class VertexOrEdgeKey, class VertexOrEdgeConstIterator>
class Sawyer::Container::GraphHashIndex< VertexOrEdgeKey, VertexOrEdgeConstIterator >

Hash-based indexing.

This index has O(N) insert, erase, and lookup times, although nominally the times are constant because the index uses hashing. The vertex or edge keys must have a hash function appropriate for boost::unordered_map and an equality operator.

The semantics for each of the class methods are documented in GraphVoidIndex.
