Can somebody help converting this from 7 to 8?

grid.setCellDescriptionGenerator(new Grid.CellDescriptionGenerator() {
    @Override
    public String getDescription(Grid.CellReference cellReference) {
        c1 = "cell1".equals(cellReference.getPropertyId());
        c2 = "cell2".equals(cellReference.getPropertyId());
        c3 = "cell3".equals(cellReference.getPropertyId());
        c4 = "cell4".equals(cellReference.getPropertyId());
        descr = (String)cellReference.getItem().getItemProperty("description").getValue();
        return ((c1 || c2 || c3 || c4)?descr:null);
    }
});

Grid<MyPojo> grid = new Grid<>(MyPojo.class);
        grid.getColumns().stream()
                .filter(column -> "cell1".equals(column.getId()) || "cell2".equals(column.getId())
                        || "cell3".equals(column.getId()) || "cell4".equals(column.getId()))
                .forEach(column -> column.setDescriptionGenerator(pojo -> pojo.getDescription()));

or with each individual column

private String getDescription(MyPojo pojo) {
        return pojo.getDescription();
    }

        Grid<MyPojo> grid = new Grid<>(MyPojo.class);
        grid.getColumn("cell1").setDescriptionGenerator(this::getDescription);
        grid.getColumn("cell2").setDescriptionGenerator(this::getDescription);
        grid.getColumn("cell3").setDescriptionGenerator(this::getDescription);
        grid.getColumn("cell4").setDescriptionGenerator(this::getDescription);
