org.apache.wicket.extensions.wizard.dynamic.DynamicWizardModel

All Implemented Interfaces:

Serializable, IWizardModel, IClusterable

public class DynamicWizardModel
extends AbstractWizardModel

Wizard model that is specialized on dynamic wizards. Unlike the default, static wizard model, this model isn't very intelligent, but rather delegates much of the work and knowledge to the dynamic wizard steps it uses.

Constructor Details

DynamicWizardModel

public DynamicWizardModel(IDynamicWizardStep startStep)

Construct.

Parameters:

startStep - first step in the wizard

Method Details

getActiveStep

public IDynamicWizardStep getActiveStep()

Description copied from interface: IWizardModel

Gets the current active step the wizard should display.

Returns:

the active step.

See Also:

• IWizardModel.getActiveStep()

getStartStep

public final IDynamicWizardStep getStartStep()

Returns:

the step this wizard was constructed with (starts the wizard). Will be used for resetting the wizard, unless you override reset().

isLastAvailable

public boolean isLastAvailable()

Description copied from interface: IWizardModel

Checks if the last button should be enabled.

Returns:

true if the last button should be enabled, false otherwise.

See Also:

• IWizardModel.isLastAvailable()

isLastStep

public boolean isLastStep(IWizardStep step)

Description copied from interface: IWizardModel

Gets whether the specified step is the last step in the wizard.

Parameters:

step - the step to check

Returns:

True if its the final step in the wizard, false otherwise.

See Also:

• IWizardModel.isLastStep(org.apache.wicket.extensions.wizard.IWizardStep)

isNextAvailable

public boolean isNextAvailable()

Description copied from interface: IWizardModel

Gets whether the next button should be enabled.

Returns:

True if the next button should be enabled, false otherwise.

See Also:

• IWizardModel.isNextAvailable()

isPreviousAvailable

public boolean isPreviousAvailable()

Description copied from interface: IWizardModel

Gets whether the previous button should be enabled.

Returns:

True if the previous button should be enabled, false otherwise.

See Also:

• IWizardModel.isPreviousAvailable()

isFinishAvailable

public boolean isFinishAvailable()

Description copied from interface: IWizardModel

Gets whether the finish button should be enabled.

By default the finish button is available for the last step only.

Returns:

True if the finish button should be enabled, false otherwise.

See Also:

• IWizardModel.isLastStep(IWizardStep)
• IWizardModel.finish()

last

public void last()

Description copied from interface: IWizardModel

Takes the model to the last step in the wizard. This method must only be called if IWizardModel.isLastAvailable() returns true. Implementors should notify listeners through calling IWizardModelListener.onActiveStepChanged(IWizardStep).

See Also:

• IWizardModel.last()

next

public void next()

Description copied from interface: IWizardModel

Increments the model to the next step. This method must only be called if IWizardModel.isNextAvailable() returns true. Implementors should notify listeners through calling IWizardModelListener.onActiveStepChanged(IWizardStep).

See Also:

• IWizardModel.next()

previous

public void previous()

Description copied from interface: IWizardModel

Takes the model to the previous step.This method must only be called if IWizardModel.isPreviousAvailable() returns true. Implementors should notify listeners through calling IWizardModelListener.onActiveStepChanged(IWizardStep).

See Also:

• IWizardModel.previous()

reset

public void reset()

Description copied from interface: IWizardModel

Resets the model, setting it to the first step. Implementors should notify listeners through calling IWizardModelListener.onActiveStepChanged(IWizardStep).

See Also:

• IWizardModel.reset()

stepIterator

public Iterator<IWizardStep> stepIterator()

Description copied from interface: IWizardModel

Returns an iterator over all the steps in the model. The iteration order is not guaranteed to the be the order of visit. This is an optional operation; dynamic models can just return null, and should call init the first time a step is encountered right before rendering it.

Returns:

an iterator over all the steps of the model or null if the wizard model is not static

See Also:

• IWizardModel.stepIterator()

setActiveStep

protected final void setActiveStep(IDynamicWizardStep step)

Sets the active step.

Parameters:

step - the new active step step.
