Class Maps.HighPerformanceDoubleMap

java.lang.Object
  y.util.Maps.HighPerformanceDoubleMap

All Implemented Interfaces:

DataAcceptor, DataMap, DataProvider, EdgeMap, NodeMap

Enclosing class:

Maps

public static final class Maps.HighPerformanceDoubleMap
extends Object
implements NodeMap, EdgeMap

Implementation of a resettable high performance map for values of simple type double. A high performance map is a facade to another map which will allow to reset all bound values to a default value in constant time.

Constructor Summary

Maps.HighPerformanceDoubleMap(DataMap backingMap, double defaultValue)

Maps.HighPerformanceDoubleMap(DataProvider backingProvider, DataAcceptor backingAcceptor, double defaultValue)
