public class EODocumentController

extends EOEntityController

implements EOObjectDisplayDocument, EOEditable

The EODocumentController class provides behavior for displaying and editing enterprise objects in a user interface. EODocumentController's API is mostly specified by the interfaces EODocument and EOEditable. Additionally, much of the way that EODocumentController works is set up by its superclass, EOEntityController. Since EOEntityControllers use EOEditingContexts and EODisplayGroups to manage and display a set of enterprise objects, EODocumentControllers use them as well. However, in addition to displaying enterprise objects, document controllers also edit the displayed objects. You can insert, update, and delete enterprise objects; undo and redo unsaved changes; and save and revert.

EODocumentController provides several action methods to interact with a user. For example, the methods revert and saveIfUserConfirms open dialogs to confirm that a user wants to revert or save before performing the action. Also, many of the methods open dialogs when an error occurs, telling the user what happened.

EODocumentController defines the concept of a root document controller. A document controller is the root document controller if none of its supercontrollers conform to EODocument. A root document controller usually provides the editing context for all its descendent document controllers -- the subcontrollers typically don't create their own. Consequently, the root document controller has responsibilities that non-root document controllers don't have. For example, only the root document controller provides save and revert behavior.

Conformance to EODocument. Returns whether the receiver is a document for the enterprise object associated with globalID and entityName. See the method description of isDocumentForGlobalID in the interface specification for EODocument. EODocumentController's default implementation returns true if the receiver is a root document controller and receiver's display group displays only the specified object. Subclasses might have to override this method to return false, for example list controllers can't really be documents for a single object and should return false.

Specified by:

isDocumentForGlobalID in interface EODocument

Parameters:

globalID - the EOGlobalID of the enterprise object

entityName - the name of the entity of the enterprise object

Returns:

true if the revert succeeded; false otherwise

See Also:

revertChanges(boolean)

revertAndMakeInvisible

public boolean revertAndMakeInvisible()

Attempts to revert the receiver's editing context changes and makes the receiver's user interface invisible if the revert succeeded (which usually results in a window closing). The user is not given the choice to cancel the operation.

Returns:

true if the save succeeded; false if the save failed or the user chose to not save

revertChanges

public boolean revertChanges(boolean showErrorDialog)

Tells the receiver's editing context to revert changes and updates the receiver's editing state on success. If the revert fails, catches the exception and invokes revertFailed to show the reason for failure. Returns whether the revert succeeded.

See Also:

revertFailed(Exception, boolean)

revertFailed

protected void revertFailed(Exception exception,
                            boolean showErrorDialog)

Invoked from revertChanges if the revert failed. If showErrorDialog is true, brings the receiver's user interface to the front and opens a dialog displaying exception's class name and exception message. This method can be overridden by subclasses to handle revert errors in a special way.

Parameters:

exception - the exception causing the save error

showErrorDialog - true if the controller should show an error dialog; false otherwise

See Also:

revertChanges(boolean)

save

public boolean save()

Saves the receiver's editing context changes by invoking saveChanges, requesting an error dialog upon failure. Returns whether the save succeeded.

Specified by:

save in interface EODocument

Returns:

true if the save succeeded; false otherwise

See Also:

saveChanges(boolean, String)

saveAndMakeInvisible

public boolean saveAndMakeInvisible()

Attempts to save the receiver's editing context changes and makes the receiver's user interface invisible if the save succeeded (which usually results in a window closing). The user is not given the choice to cancel the operation.

Returns:

saveChanges

public boolean saveChanges(boolean showErrorDialog,
                           String saveOperationTitle)

Tells the receiver's editing context to save changes and updates the receiver's editing state on success. If the save fails, catches the exception and invokes saveFailed to show the reason for failure. Returns whether the save succeeded.

Some applications need to disable undo operations after a save. You can override this method to do so, for example:

  public boolean saveChanges(boolean showErrorDialog, String saveOperationTitle) {
      if (super.saveChanges(showErrorDialog, saveOperationTitle)) {
          editingContext().undoManager().removeAllActions();
      }

Parameters:

showErrorDialog - true if the controller should show a dialog if the save fails; false otherwise

saveOperationTitle - a description of the operation causing the save

                          String saveOperationTitle)

Invoked from saveChanges if the save failed. If showErrorDialog is true, brings the receiver's user interface to the front and opens a dialog displaying exception's class name and exception message. This method can be overridden by subclasses to handle save errors in a special way.
