All Implemented Interfaces:

java.io.Serializable

public class TransposeDataCollection2D
extends AbstractDataStructureMap<java.util.Map<java.lang.Object,TransposeDataCollection>>

Data structure which stores internally a Map. This data structure is usually used when we want to store the values of a particular variable separately per each category or group combination. The class provides a number of methods to access and modify the internal map.
