                           IRowDataProvider<T> rowDataProvider)
        Create a E4SelectionListener and registers it to the given SelectionLayer.
        Parameters:
        service - The ESelectionService to which the selection should be published to.
        selectionLayer - The SelectionLayer that is used to retrieve the selection.
        rowDataProvider - The IRowDataProvider to access the selected row data.

    • Method Detail

      • isFullySelectedRowsOnly

        public boolean isFullySelectedRowsOnly()
        Returns:
        true if only fully selected rows should be used to populate the selection or if any selection should be populated. Default is true.

      • setFullySelectedRowsOnly

        public void setFullySelectedRowsOnly​(boolean fullySelectedRowsOnly)
        Parameters:
        fullySelectedRowsOnly - true if only fully selected rows should be used to populate the selection false if any selection should be populated.

      • isHandleSameRowSelection

        public boolean isHandleSameRowSelection()
        Returns:
        true if a selection should only be handled by the ESelectionService if the row selection changes or if just another column is selected.

      • setHandleSameRowSelection

        public void setHandleSameRowSelection​(boolean handleSameRowSelection)
        Parameters:
        handleSameRowSelection - true if a selection should only be handled by the ESelectionService if the row selection changes or if just another column is selected.

      • isProcessColumnSelection

        public boolean isProcessColumnSelection()
        Returns:
        true if column selection should trigger setting the selection via ESelectionService (that means basically a select all), false if not (needed for huge datasets to avoid a select all).

      • setProcessColumnSelection

        public void setProcessColumnSelection​(boolean processColumnSelection)
        Configure whether column selections should start row selection processing or not.

        This is necessary to handle issues with huge datasets. Dependent on different configurations, selecting a column can cause the selection of all rows in a table, which would then lead to populate the whole dataset as selection via this provider. Setting the processColumnSelection flag to false will skip processing to avoid such issues.

        Parameters:
        processColumnSelection - true to process row selection in case of column selections (default) false to skip processing in case of column selections to avoid issues on large datasets.

      • isMultiSelection

        public boolean isMultiSelection()
        Returns:
        true if a list of data values should be set as selection or a single value.

      • setMultiSelection

        public void setMultiSelection​(boolean multiSelection)
        Set this value to true if a list of values should be set as selection to the ESelectionService or false if only a single value object should be set.
        Parameters:
        multiSelection - true if a list of data values should be set as selection or a single value.
