Detailed Description

template<typename Cluster>
class OpenMS::HashGrid< Cluster >

Container for (2-dimensional coordinate, value) pairs.

A hash-grid consists of hash-grid cells. The key of each cell is a pair of integers. Each pair is assigned to a cell using a hash function.

This container implements most parts of the C++ standard map interface.

Template Parameters
ClusterType to be stored in the hash grid. (e.g. HierarchicalClustering::Cluster)
