java.lang.Object
   com.sun.rave.web.ui.event.TableSelectPhaseListener

TableSelectPhaseListener
public class TableSelectPhaseListener implements PhaseListener(Code)
A utility class for radiobutton and checkbox components used to select rows of a table.

Note: UI guidelines recomend that rows should be unselected when no longer in view. For example, when a user selects rows of the table and navigates to another page. Or, when a user applies a filter or sort that may hide previously selected rows from view. If a user invokes an action to delete the currently selected rows, they may inadvertently remove rows not displayed on the current page. Using TableSelectPhaseListener ensures that invalid row selections are not rendered by clearing selected state after the render response phase. That said, there are cases when maintaining state across table pages is necessary. In this scenario, use the keepSelected method to prevent state from being cleared by this instance.

Note: To see the messages logged by this class, set the following global defaults in your JDK's "jre/lib/logging.properties" file.

 java.util.logging.ConsoleHandler.level = FINE
 com.sun.rave.web.ui.event.TableSelectPhaseListener.level = FINE
 




Constructor Summary
public  TableSelectPhaseListener()
    
public  TableSelectPhaseListener(boolean keepSelected)
     Construct an instance with the given flag indicating that selected objects should not be cleared after the render response phase.
public  TableSelectPhaseListener(Object unselected)
     Construct an instance with an unselected parameter.

The unselected parameter is only required if a primitve value is being used for the selecteValue attribute of the checkbox or radiobutton.


Method Summary
public  voidafterPhase(PhaseEvent event)
     Called during the JSF Lifecycle after the RENDER_RESPONSE phase.
public  voidbeforePhase(PhaseEvent event)
     Called during the JSF Lifecycle before the RENDER_RESPONSE phase.
public  voidclear()
     Clear all selected objects.
public  PhaseIdgetPhaseId()
     Get the phase id.
public  ObjectgetSelected(RowKey rowKey)
     Get the selected object from this instance.

Note: Call this method from the get method that that is bound to the selected attribute.


Parameters:
  rowKey - The current RowKey.
public  booleanisKeepSelected()
     Test if the flag indicating that selected objects should be cleared after the render response phase.
public  booleanisSelected(RowKey rowKey)
     Test if the object associated with the given RowKey is selected.
Parameters:
  rowKey - The current RowKey.
public  voidkeepSelected(boolean keepSelected)
     Set the flag indicating that selected objects should be cleared after the render response phase.
public  voidsetSelected(RowKey rowKey, Object object)
     Set the selected object for this instance.


Constructor Detail
TableSelectPhaseListener
public TableSelectPhaseListener()(Code)
Default constructor



TableSelectPhaseListener
public TableSelectPhaseListener(boolean keepSelected)(Code)
Construct an instance with the given flag indicating that selected objects should not be cleared after the render response phase.
Parameters:
  keepSelected - If true, ojects are not cleared.



TableSelectPhaseListener
public TableSelectPhaseListener(Object unselected)(Code)
Construct an instance with an unselected parameter.

The unselected parameter is only required if a primitve value is being used for the selecteValue attribute of the checkbox or radiobutton. If the selectedValue property is an Object value then unselected can be null. If however it is a primitive type then it should be the MIN_VALUE constant instance of the wrapper Object type. For example if the application is assigning int values to selectedValue then unselected should be new Integer(Integer.MIN_VALUE).


Parameters:
  unselected - the object to return for an unselected checkbox.




Method Detail
afterPhase
public void afterPhase(PhaseEvent event)(Code)
Called during the JSF Lifecycle after the RENDER_RESPONSE phase.
Parameters:
  event - The PhaseEvent object.



beforePhase
public void beforePhase(PhaseEvent event)(Code)
Called during the JSF Lifecycle before the RENDER_RESPONSE phase.
Parameters:
  event - The PhaseEvent object.



clear
public void clear()(Code)
Clear all selected objects.



getPhaseId
public PhaseId getPhaseId()(Code)
Get the phase id.



getSelected
public Object getSelected(RowKey rowKey)(Code)
Get the selected object from this instance.

Note: Call this method from the get method that that is bound to the selected attribute.


Parameters:
  rowKey - The current RowKey. The selected object.



isKeepSelected
public boolean isKeepSelected()(Code)
Test if the flag indicating that selected objects should be cleared after the render response phase. true if ojects are not to be cleared.



isSelected
public boolean isSelected(RowKey rowKey)(Code)
Test if the object associated with the given RowKey is selected.
Parameters:
  rowKey - The current RowKey. A true or false value.



keepSelected
public void keepSelected(boolean keepSelected)(Code)
Set the flag indicating that selected objects should be cleared after the render response phase.
Parameters:
  keepSelected - Selected objects are kept true, cleared if false.



setSelected
public void setSelected(RowKey rowKey, Object object)(Code)
Set the selected object for this instance.

Note: Call this method from the set method that that is bound to the selected attribute.


Parameters:
  rowKey - The current RowKey.
Parameters:
  object - The selected object.
