public class JUCtrlParameterBinding
extends JUCtrlAttrsBinding

A JUControlBinding class responsible for binding controls/models that are bound to a single Row object in the BC4J layer. This class is responsible for:

• Updating the Control Bindings with attribute values from the BC4J Row object for all attributes that this Control Binding is bound to.
• Enabling/disabling the control based on whether the corresponding Row's attribute is updateable.

This class defines the abstract APIs for subclasses to implement, so that Row's attributes can be passed to the Binding object for appropriate display/update.

Constructor Detail

JUCtrlParameterBinding

protected JUCtrlParameterBinding()

*** For internal framework use only ***

JUCtrlParameterBinding

public JUCtrlParameterBinding(java.lang.Object control,
                      java.lang.String expression)

Creates a binding between the given control and attributes in the Rows returned by the passed in Iterator Binding.

Method Detail

getValueAt

public java.lang.Object getValueAt(int attrIndex)

Gets the value from the control for the attribute at the given index. (The index is calculated from the list of attributes this control binding is bound to as passed in the constructor). Framework uses this method to get the attribute value from the control and pass it on to the Row object on the BC4J side.

Overrides:

getValueAt in class JUCtrlAttrsBinding

setValueAt

public void setValueAt(java.lang.Object value,
              int attrIndex)

Updates the control/control-binding with the latest value of the attribute at the given index with the given value. This method is used by the framework to update the control with attribute values from a BC4J row.

Overrides:

setValueAt in class JUCtrlAttrsBinding

addControlToPanel

public void addControlToPanel(java.lang.Object panel,
                     java.lang.Object layoutObject,
                     java.lang.Object layoutCons)

Description copied from class: JUControlBinding

*** For internal framework use only ***

Overrides:

addControlToPanel in class JUCtrlAttrsBinding

setDataValueAt

public void setDataValueAt(java.lang.Object value,
                  int attrIndex)

Overrides:

setDataValueAt in class JUCtrlAttrsBinding

updateValuesFromRows

public void updateValuesFromRows(Row[] rows,
                        boolean clear)

Passes on the first row from the given array of rows to updateValuesFromRow() method to update the bound control's display.

Overrides:

updateValuesFromRows in class JUCtrlAttrsBinding

updateRangeScrolled

public void updateRangeScrolled(ScrollEvent event)

Overridden as a no-op. Since this control is bound to only one row, when that row becomes current the framework uses updateValuesFromRow to update the display

Overrides:

updateRangeScrolled in class JUCtrlValueBinding

See Also:

ScrollEvent

updateNavigated

public void updateNavigated(NavigationEvent event)

Overridden as a no-op. Since this control is bound to only one row, when that row becomes current the framework uses updateValuesFromRow to update the display

Overrides:

updateNavigated in class JUCtrlValueBinding

refreshControl

public void refreshControl()

*** For internal framework use only ***

Updates the values in a control that is bound using an Iterator already in use. (a valid row iterator) If you do not call this method, your control won't update unless you refresh the Iterator.

Overrides:

refreshControl in class JUCtrlAttrsBinding

isControlQueriable

protected final boolean isControlQueriable()

Parameters are not queriable, should not participate in findmode

Overrides:

isControlQueriable in class JUCtrlAttrsBinding

isAttributeUpdateable

protected boolean isAttributeUpdateable(Row row,
                            int index)

return true if this binding is not marked READONLY

Overrides:

isAttributeUpdateable in class JUCtrlValueBinding

getAttributeDefs

public final AttributeDef[] getAttributeDefs()

Return this binding's definition in an AttributeDef[].

Specified by:

getAttributeDefs in interface StructureDef

Overrides:

getAttributeDefs in class JUCtrlValueBinding

Returns:

an array of attribute definitions.
