public class JUCtrlAttrsBinding
extends JUCtrlValueBinding
implements oracle.adf.model.AttributeBinding

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

### JUCtrlAttrsBinding

    protected JUCtrlAttrsBinding()

  *** For internal framework use only ***

### JUCtrlAttrsBinding

    public JUCtrlAttrsBinding(java.lang.Object control,
                              oracle.adf.model.binding.DCIteratorBinding iterBinding,
                              java.lang.String[] attrNames)

  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.

### 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.

### 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 ***
  Specified by:
    `addControlToPanel` in class `JUControlBinding`

### setDataValueAt

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

### updateValuesFromRow

    public void updateValuesFromRow(Row row)

  Updates the control-binding and hence the control with attribute values from the attributes of this Row. Invokes setValueAt() with the attribute value and attribute index with respect to attributes for which this binding is interested.

  This method also enables/disables the Swing control based on the updateability of the first (Default) attribute to which this control is bound.

  Overrides:
    `updateValuesFromRow` in class `JUCtrlValueBinding`

### setControlEnabled

    protected void setControlEnabled(boolean flag)

### 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.
  Specified by:
    `updateValuesFromRows` in class `JUCtrlValueBinding`

### 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
  Specified by:
    `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
  Specified by:
    `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.

### isControlQueriable

    protected boolean isControlQueriable()

  Description copied from class: `oracle.adf.model.binding.DCControlBinding`
  Returns true if this control can participate in find form. Note that some controls like ProgressBar cannot participate in a find form as they do no accept user inputs. By default this method returns false and it's up to the individual control bindings to determine whether they can participate in a find mode.

### createAttributeBinding

    public static JUCtrlAttrsBinding createAttributeBinding(JUFormBinding formBinding,
                                                            java.lang.Object control,
                                                            java.lang.String voInstanceName,
                                                            java.lang.String voIterName,
                                                            java.lang.String voIterBindingName,
                                                            java.lang.String attrName)

  This method is used by the JDeveloper designtime wizards for binding a text component with an attribute of rows of a ViewObject/RowIterator. This method calls JUFormBinding.getRowIterBinding to get the iterator binding using the given parameters and then registers a new JUTextFieldBinding with the iterator binding object so as to display/edit the current row's attribute of the given name.
  Parameters:
    `formBinding` - The containing JUPanelBinding in which the given iterator binding would be found/created.
    `control` - The control instance to bind to a ViewObject's attribute.
    `voInstanceName` - Name of the instance of the ViewObject in a BC4J ApplicationModule.
    `voIterName` - Runtime instance name of the iterator in the ViewObject (optional).
    `voIterBindingName` - Instance name of the iterator binding that uniquely identifies an iterator binding object used to read/write data in this given JUPanelBinding instance.
    `attrName` - The name of the attribute of this ViewObject rows that contains data to display/edit in the associated text control.
  Returns:
    Document object bound to the given text control.

### toString

    public java.lang.String toString()
