Direct Known Subclasses:

JUActionBinding

public abstract class JUCtrlActionBinding

extends JUControlBinding

Implements actions on BC4J RowIterator to which this control is bound. This class supports the following actions:

• ACTION_EXECUTE Executes the ViewObject query.
• ACTION_NEXT Moves the currency to the next row.
• ACTION_PREVIOUS Moves the currency to the previous row.
• ACTION_FIRST Moves the currency to the first row.
• ACTION_LAST Moves the currency to the last row.
• ACTION_RESET Resets the currency to the beginning of the RowIterator.
• ACTION_REMOVE_CURRENT_ROW Removes the current row in this iterator.
• ACTION_CREATE_INSERT_ROW Creates a new row and insert it into this iterator before the current row.
• ACTION_COMMIT_TRANSACTION Commits all changes in the current BC4J application module session into database.
• ACTION_ROLLBACK_TRANSACTION Rolls back any changes in the current BC4J application module session.

If a button is bound to this binding class, then, on button press, the action event on the button binding should call doIt() method on this object to perform the desired action.

Constructor Detail

JUCtrlActionBinding

public JUCtrlActionBinding(java.lang.Object control,
                           JUIteratorBinding iterBinding,
                           int action)

Creates an ActionBinding instance that works with the given control and on control's ActionEvent, call the doIt() method.

Parameters:

control - The control that this binding works with.

iterBinding - JUIteratorBinding instance that this binding works with.

action - Indicates the selected action from the list of actions this class implements.

Method Detail

public static int actionNameToId(java.lang.String actionName)

*** For internal framework use only ***

actionIdToName

public static java.lang.String actionIdToName(int id)

*** For internal framework use only ***

doIt

public void doIt()

Invokes the action that this binding is selected to perform. This method gets the RowIterator from the associated Iterator binding and then calls an equivalent method on the RowIterator. BC4J runtime then sends appropriate events to various binding objects based on the action to update their display with the latest currency, data, etc.

Here's a list of actions and corresponding method calls on the BC4J side.

• ACTION_EXECUTE Calls ViewObject.executeQuery() on the corresponding ViewObject to which this binding's RowIterator belongs to.
• ACTION_NEXT Calls RowIterator.next() after generating beforeRowNavigated event on the associated JUFormBinding (if currency is moved from an existing current row to another one.)
• ACTION_PREVIOUS Calls RowIterator.previous() after generating beforeRowNavigated event on the associated JUFormBinding (if currency is moved from an existing current row to another one.)
• ACTION_FIRST Calls RowIterator.first() after generating beforeRowNavigated event on the associated JUFormBinding (if currency is moved from an existing current row to the first row.)
• ACTION_LAST Calls RowIterator.last() after generating beforeRowNavigated event on the associated JUFormBinding (if currency is moved from an existing current row to the last row.)
• ACTION_RESET Reset the currency to the beginning of the RowIterator by calling RowIterator.reset() after generating beforeRowNavigated event if currency is taken away from an existing current row.
• ACTION_REMOVE_CURRENT_ROW Remove the current row in this iterator by calling RowIterator.removeCurrentRow()
• ACTION_CREATE_INSERT_ROW Create a new row and insert it into this iterator before the current row after generating beforeRowNavigated event on the containing JUFormBinding.
• ACTION_COMMIT_TRANSACTION Commit all changes in the current BC4J application module session into database by calling commit() method on the related BC4J Transaction object.
• ACTION_ROLLBACK_TRANSACTION Rollback any changes in the current BC4J application module session by calling rollback() method on the related BC4J Transaction object. This method also re-executes the Form (all VOs in the JUFormBinding) after a successful rollback.
