Observable Matrix

ATTENTION: THIS PROJECT CONTINUES TO LIVE IN THE FOLLOWING PROJECT: Toolbox

An array based observable matrix implemented in Java.

It will fire the following events:

• MColumnEvent (COLUMN_ADDED, COLUMN_REMOVED)
• MRowEvent (ROW_ADDED, ROW_REMOVED)
• MItemEvent (ITEM_ADDED, ITEM_REMOVED, ITEM_CHANGED)
• MColumnsEvent (NO_OF_COLUMNS_CHANGED)
• MRowsEvent (NO_OF_ROWS_CHANGED)

All events are extending MEvent and so you could either subscribe to specific events e.g.

matrix.setOnItemChanged(e -> { ... })

matrix.setOnMEvent(MItemEvent.ITEM_CHANGED, event -> { ... });

or you could subscribe to a group of event e.g.

matrix.setOnMEvent(MItemEvent.ANY, event -> { ... });

The matrix can hold objects of any type, initialize it as follows

// Matrix with Integer objects
ObservableMatrix<Integer> integerMatrix = new ObservableMatrix<>(Integer.class, 3, 2);

// Matrix with JavaFX Label objects
ObservableMatrix<Label> labelMatrix = new ObservableMatrix<>(Label.class, 5, 5);

The matrix supports methods for the following operations:

• getItemAt(int x, int y)
• setItemAt(int x, int y, T item) {
• removeItemAt(int x, int y) {
• removeItem(T item) {
• contains(T item) {
• getIndicesOf(T item) {
• getMatrix() { return matrix; }
• getAllItems() { return stream().filter(Objects::nonNull).collect(Collectors.toList()); }
• stream()
• reset()
• getCol(int col)
• getRow(int row)
• isColEmpty(int col)
• isRowEmpty(int row)
• getNoOfCols()
• setCols(int cols)
• addCol(int at, Supplier itemSupplier)
• addCol(int at, List items)
• addNullCol(int at)
• removeCol(int at)
• addRow(int at, Supplier itemSupplier)
• addRow(int at, List items)
• addNullRow(int at)
• removeRow(int at)
• getNoOfRows()
• setRows(int rows)
• getAllColumns()
• getAllEmptyColumns()
• getAllRows()
• getAllEmptyRows()
• getResizeMatrixWhenInnerRowOrColIsRemoved()

• setResizeMatrixWhenInnerRowOrColIsRemoved(boolean resize)

  Please find a little example in the Demo class.
