M - grid model object typeI - row/item model object typepublic abstract class AbstractLightWeightColumn<M,I>
Convenience implementation of IGridColumn. This class should be used as base for
lightweight columns.
Contains getters and setters for most properties and takes care of the header component. The only
method necessary to implement is newCell(IModel).

public AbstractLightWeightColumn(String columnId,
IModel<String> headerModel,
String sortProperty)
columnId - column identifier - must be unique within the gridheaderModel - model for column titlesortProperty - optional string that will be returned by ISortState to indicate that the
column is being sorted

public boolean isLightWeight(IModel<I> rowModel)
IRenderable implementation. Generally, if the cell is non-interactive (label only),
it's better to use an IRenderable implementation, as it has zero memory footprint
isLightWeight in interface IGridColumn<M,I>isLightWeight in class AbstractColumn<M,I>rowModel - model for given row
true if the cell is lightweight, false otherwisepublic abstract IRenderable<I> newCell(IModel<I> rowModel)
IRenderable instance that is used to render to render the output of
cell for given row. This method is called for rows that are lightweight (
IGridColumn.isLightWeight(IModel) returns true ).
