All Implemented Interfaces:

TwoDModel

public class ArrayTwoDModel

extends AbstractTwoDModel

An ArrayTwoDModel is a two dimensional data source that stores data in a two dimensional array. Clients can specify how many columns and rows the ArrayTwoDModel contains at creation time. Clients can add and remove columns and rows with the addColumns, removeColumns, addRows, removeRows methods. Clients can set the data for a cell with the setData method.

ArrayTwoDModel sends the proper TwoDModelEvents to the list of registered listeners.
