      • handleLayerEvent

        public void handleLayerEvent​(ILayerEvent event)
        Description copied from class: AbstractLayer
        Handle layer event notification. Convert it to your context and propagate UP. If you override this method you MUST NOT FORGET to raise the event up the layer stack by calling super.fireLayerEvent(event) - unless you plan to eat the event yourself.
        Specified by:
        handleLayerEvent in interface ILayerListener
        Overrides:
        handleLayerEvent in class AbstractRowHideShowLayer
        Parameters:
        event - the event

      • saveState

        public void saveState​(String prefix,
                      Properties properties)
        Description copied from interface: IPersistable
        Saves the state to the given Properties using the specified prefix. Note: The prefix must be prepended to the property key to support multiple states within one Properties instance.
        Specified by:
        saveState in interface IPersistable
        Overrides:
        saveState in class AbstractLayerTransform
        Parameters:
        prefix - The prefix to use for the state keys. Is also used as the state configuration name.
        properties - The Properties instance to save the state to.

      • loadState

        public void loadState​(String prefix,
                      Properties properties)
        Description copied from class: AbstractLayerTransform
        Underlying layers must load state first. If this is not done, IStructuralChangeEvent from underlying layers will reset caches after state has been loaded
        Specified by:
        loadState in interface IPersistable
        Overrides:
        loadState in class AbstractLayerTransform
        Parameters:
        prefix - The prefix to use for the state keys. Is also used as the state configuration name.
        properties - The Properties instance to load the state from.

      • getConfigLabelsByPosition

        public LabelStack getConfigLabelsByPosition​(int columnPosition,
                                            int rowPosition)
        Description copied from interface: ILayer
        Returns the config labels for the cell at the given coordinates. Needed to retrieve the corresponding configurations out of the IConfigRegistry.
        Specified by:
        getConfigLabelsByPosition in interface ILayer
        Overrides:
        getConfigLabelsByPosition in class AbstractLayerTransform
        Parameters:
        columnPosition - The column position of the cell.
        rowPosition - The row position of the cell.
        Returns:
        The LabelStack with the config labels for the cell at the given coordinates.

      • isRowIndexHidden

        public boolean isRowIndexHidden​(int rowIndex)
        Description copied from class: AbstractRowHideShowLayer
        Will check if the row at the specified index is hidden or not. Checks this layer and also the sublayers for the visibility.
        Specified by:
        isRowIndexHidden in class AbstractRowHideShowLayer
        Parameters:
        rowIndex - The row index of the row whose visibility state should be checked.
        Returns:
        true if the row at the specified index is hidden, false if it is visible.

      • getHiddenRowIndexes

        public Collection<Integer> getHiddenRowIndexes()
        Description copied from class: AbstractRowHideShowLayer
        Will collect and return all indexes of the rows that are hidden in this layer.

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

        Since 2.0 it is recommended to use AbstractRowHideShowLayer.getHiddenRowIndexesArray() to avoid unnecessary autoboxing operations.

        Specified by:
        getHiddenRowIndexes in class AbstractRowHideShowLayer
        Returns:
        Collection of all row indexes that are hidden in this layer.

      • getHiddenRowIndexesArray

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

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

        Specified by:
        getHiddenRowIndexesArray in class AbstractRowHideShowLayer
        Returns:
        All row indexes that are hidden in this layer.
