Class ColumnGroupExpandCollapseLayer

    • Constructor Detail

      • ColumnGroupExpandCollapseLayer

        public ColumnGroupExpandCollapseLayer​(IUniqueIndexLayer underlyingLayer)

    • Method Detail

      • doCommand

        public boolean doCommand​(ILayerCommand command)
        Description copied from interface: ILayer
        Opportunity to respond to a command as it flows down the stack. If the layer is not interested in the command it should allow the command to keep traveling down the stack.

        Note: Before the layer can process a command it must convert the command to its local coordinates using ILayerCommand.convertToTargetLayer(ILayer)

        Specified by:
        doCommand in interface ILayer
        Overrides:
        doCommand in class AbstractLayerTransform
        Parameters:
        command - The command to execute.
        Returns:
        true if the command has been handled and was therefore consumed, false otherwise.

      • isColumnIndexHidden

        public boolean isColumnIndexHidden​(int columnIndex)
        Description copied from class: AbstractColumnHideShowLayer
        Will check if the column at the specified index is hidden or not.
        Specified by:
        isColumnIndexHidden in class AbstractColumnHideShowLayer
        Parameters:
        columnIndex - The column index of the column whose visibility state should be checked.
        Returns:
        true if the column at the specified index is hidden, false if it is visible.

      • getHiddenColumnIndexesArray

        public int[] getHiddenColumnIndexesArray()
        Description copied from class: AbstractColumnHideShowLayer
        Will collect and return all indexes of the columns that are hidden in this layer.

        Note: It is not intended that it also collects the column indexes of underlying layers. This would cause issues on calculating positions, as every layer is responsible for those calculations itself.

        Specified by:
        getHiddenColumnIndexesArray in class AbstractColumnHideShowLayer
        Returns:
        All column indexes that are hidden in this layer.
