public class DefaultDataValueRenderer
- extends DefaultTableCellRenderer
- implements DataValueRenderer
Default implementation for a renderer for
DataValue
objects. This class should be used
(better: derived from) when the rendering is only a string representation
of the DataValue
object. It's recommended to derive this class
and overwrite the DefaultTableCellRenderer.setValue(Object)
and
the getDescription()
methods. A correct implementation of
setValue(Object)
will test if the argument object is of the
expected DataValue
class and call
super.setValue(Object)
with the desired string representation.

DefaultDataValueRenderer
public DefaultDataValueRenderer()
- Creates new instance given a null column spec.
DefaultDataValueRenderer
public DefaultDataValueRenderer(DataColumnSpec spec)
- Creates new renderer and memorizes the column spec. The argument may
be, however, null.
- Parameters:
spec
- The column spec of the column for which this renderer is
used.
getDescription
public String getDescription()
- Get a description for this renderer implementation. It will serve
to identify this renderer when the user has the choice of different
renderer that are available. Make sure that this description is likely
to be unique (if not only one of renderer with this ID
is shown as available) and this description is short but "expressive" so
that it can be shown as label in menus, for instance.
- Specified by:
getDescription
in interface DataValueRenderer
- Returns:
- A description for this renderer.
getListCellRendererComponent
public Component getListCellRendererComponent(JList list,
Object value,
int index,
boolean isSelected,
boolean cellHasFocus)
-
- Specified by:
getListCellRendererComponent
in interface ListCellRenderer
getRendererComponent
public Component getRendererComponent(Object val)
- Get a component that visualizes a given object. This object, generally,
is a
DataCell
implementing the underlying
DataValue
interface. The implementation, however, needs to
handle other cases as well, such as null
arguments,
missing DataCell
or generic objects.
- Specified by:
getRendererComponent
in interface DataValueRenderer
- Parameters:
val
- The value to render
- Returns:
- A component displaying the content of
val
.
getColSpec
protected DataColumnSpec getColSpec()
- Get reference to the constructor's argument. The return value may be
null (in particular if the empty constructor has been used).
- Returns:
- The column spec for this renderer.
accepts
public boolean accepts(DataColumnSpec spec)
- Returns always
true
.
Is this renderer instance able to render the content of the column
given by spec
. Most implementations will return
true
here but some may require some properties to be
set, for instance a molecule renderer needs to have 2D coordinates
in the column.
Note: This method is not used to test whether arbitrary types
can be renderer by this renderer instance but rather if the specific
runtime column spec (containing the type) is appropriate, for instance
contains domain information or certain properties are set.
- Specified by:
accepts
in interface DataValueRenderer
- Parameters:
spec
- The column spec to check.
- Returns:
true
if this renderer can be chosen to render
the content of the column.
