Constructor Detail

SmAppSettingsModel

public SmAppSettingsModel()

Method Detail

doSave

public void doSave()
            throws java.io.IOException

Executes the save command in the model. This saves the changes since the last save persistently.

Throws:

java.io.IOException - thrown when the data could not be saved persistently. This should lead to a visual indication to the user.

doUpdate

public void doUpdate()

Instructs the model to do an update of its data. Many EodispModels are just intermediated models for view components and do not hold the actual data. The actual data is usually retrieved and maintained by a persistency framework. Thus, if the real data has been changed, a model can be informed of this updated and it can be instructed to reload the data.

This should in most cases lead to an update of the visual component representing the data as well.

Specified by:

doUpdate in interface EodispModel

Overrides:

doUpdate in class AbstractEodispModel

hasChanges

public boolean hasChanges()

Returns a value stating whether the model has some changes since the last change.

Returns:

True if the model has changes since the last change or false, if there are no changes.

redo

public void redo()

This re-performs the last command executed by the model. How a redo is implemented depends on the model. This operation might not be available on all models. Models not supporting redo should ignore such a request.

Specified by:

redo in interface EodispModel

Overrides:

redo in class AbstractEodispModel

undo

public void undo()

This makes and undo of the last command executed by the model. How an undo is implemented depends on the model. This operation might not be available on all models. Models not supporting undo should ignore such a request.

Specified by:

undo in interface EodispModel

Overrides:

undo in class AbstractEodispModel

getConfiguration

public org.eodisp.util.configuration.Configuration getConfiguration()

Returns the configuration class that holds the entries.

Returns:

The configuration class.
