nl.gx.webmanager.handler.util.TableMap

All Implemented Interfaces:

Serializable, Cloneable, Map

Direct Known Subclasses:

ThreeDimMap

public class TableMap
extends LinkedHashMap

Usefull class for storing 2-dimensional data that needs to be accessed by it's coordinates. The data structure consist of a Map of Maps of Objects. Inner maps are automatically created when putting values. The datastructure uses LinkedHashMaps, so it is order preserving. Use the getEntrySet() method from Map, to iterate over the objects in the order they were added.
