Class QuadrupleMapNodeData

java.lang.Object

cz.vutbr.web.domassign.QuadrupleMapNodeData

All Implemented Interfaces:

NodeData

public class QuadrupleMapNodeData
extends Object
implements NodeData

Implementation of NodeData by four distinct HashMaps. According to tests, it is about 25% faster then SingleDataMap when retrieving values and inheriting but occupies up to 100% more memory.
