      • isConsecutive

        public static boolean isConsecutive​(int[] pos)
        Test if the numbers in the given array are consecutive. If there are duplicates or gaps in the array, false will be returned.
        Parameters:
        pos - the array of numbers to check

      • hasConsecutiveSelection

        public static boolean hasConsecutiveSelection​(SelectionLayer selectionLayer)
        Checks whether the selected region tracked by the given SelectionLayer is consecutive or not.
        Parameters:
        selectionLayer - The SelectionLayer that tracks the selection.
        Returns:
        true if the current selection is consecutive, false if not.
        Since:
        1.4

      • getBottomRightCellInSelection

        public static ILayerCell getBottomRightCellInSelection​(SelectionLayer selectionLayer)
        Returns the bottom right cell of a selected region. Will only return an ILayerCell if the selected region is consecutive. Otherwise null will be returned.
        Parameters:
        selectionLayer - The SelectionLayer needed to determine the selection.
        Returns:
        The bottom right cell of a selected region or null if the selected region is not consecutive.
        Since:
        1.4

      • getSelectedRowObjects

        public static <T> List<T> getSelectedRowObjects​(SelectionLayer selectionLayer,

                                                boolean fullySelectedRowsOnly)
        Inspects the current selection on the given SelectionLayer and returns a list of the corresponding list item objects. Uses the IRowDataProvider to be able to determine the row objects per selected row position.
        Parameters:
        selectionLayer - The SelectionLayer to retrieve the selected row indexes from.
        rowDataProvider - The IRowDataProvider to retrieve the object for the row index.
        fullySelectedRowsOnly - Flag to determine if only fully selected rows should be taken into account.
        Returns:
        The list of all objects that are currently marked as selected. Never null.
