Class AbstractCellRenderer

java.lang.Object

webwork.view.taglib.ui.table.renderer.AbstractCellRenderer

All Implemented Interfaces:

CellRenderer

Direct Known Subclasses:

BooleanCellRenderer, DateCellRenderer, DefaultCellRenderer, FixedTextCellRenderer, LinkCellRenderer, NumericCellRenderer

public abstract class AbstractCellRenderer
extends Object
implements CellRenderer

this is the base class that most renderers will be derived from. It allows setting the alignment. Subclasses should set there actuall content by implementing getCellValue

renderCell

public String renderCell(WebTable table,
                Object data,
                int row,
                int col)

implememnts CellRenderer renderCell. It sets the alignment. gets the actual data from getCellValue

Specified by:

renderCell in interface CellRenderer

getCellValue

protected abstract String getCellValue(WebTable table,
                  Object data,
                  int row,
                  int col)

this is the method that subclasses need to implement to set their value. they should not override renderCell unless they want to change the alignmnent renderering
