Class Step

java.lang.Object
oracle.ide.panels.MetaTraversable
oracle.ide.wizard.Step

All Implemented Interfaces:

Copyable

Direct Known Subclasses:

WizardStep

public class Step

extends MetaTraversable

The Step class is responsible for specifying metadata for a Traversable that has not yet been instantiated; Step differs from MetaTraversable in that Step is intended to be used for specifying a sequence of panels that are displayed by the FSMWizard.

The current behavior of Step is identical to MetaTraversable. Future extensions that apply only to the FSMWizard will be added to Step rather than to MetaTraversable.

Method Detail

newSteps

public static Step[] newSteps(java.lang.String[] traversableClasses)

Convenience method for creating an array of Step objects based on an array of strings that provide the fully qualified class names of the Traversables.

getPageTitle

public java.lang.String getPageTitle()

Method to get the title of the page that presents this Step

setPageTitle

public void setPageTitle(java.lang.String pageTitle)

Method to set the title of the page that presents this Step

Parameters:

pageTitle - String that represents the title of the page

getStepLabel

public java.lang.String getStepLabel()

Method to get the label of the page that presents this Step. This label will be shown in the WizardRoadMap.

setStepLabel

public void setStepLabel(java.lang.String stepLabel)

Method to set the label of the page that presents this Step

Parameters:

pageTitle - String that represents the title of the page

newTraversable

public final Traversable newTraversable(CommitNotifier commitNotifier)

This method specifies the Traversable that will be used in association with the Navigable; in general, only NavigableUIContainer implementations should call this method directly.

By default, this method uses the Class that was specified when this Navigable was created and calls Class.newInstance() on that Class to create the new Traversable. If the class is null or the class does not implement a public default constructor or the newly created object cannot be cast to Traversable, this method will return an instance of DefaultTraversablePanel. If the class implements the CommitListener interface, then the Traversable instance will be added as an CommitListener to the NavigableUIContainer as well.

Parameters:

uiContainer - Subclasses that override this method can register an CommitListener with the NavigableUIContainer.

Returns:

A Traversable which represents the detail UI component that is shown when the user selects this Navigable in the NavigableUIContainer.

copyTo

public java.lang.Object copyTo(java.lang.Object target)

Description copied from interface: Copyable

Copies the internal state of this object to the specified copy. If copy is null, then this method should create a new instance of this class and proceed to copy the internal state to the newly created object. Generally, only the persistent state of the object should be copied, but whether or not it is appropriate to copy transient properties is at the discretion of the individual implementor.

Regardless of whether the copy occurs to an existing object or to a newly created object, the return value is object to which this object's state was copied.

There is a standard implementation pattern for the copyTo method that helps avoid problems that arise when a Copyable object is subclassed. The pattern is:

    public Object copyTo( Object target )
    {
      final <this_class> copy =
        target != null ? (<this_class>) target : new <this_class>();
      copyToImpl( copy );
      return copy;
    }

    protected final void copyToImpl( <this_class> copy )
    {
      super.copyToImpl( copy );  //  if necessary
      //  put code here for copying the properties of <this_class>
    }
  

The parameter passed into the copyToImpl method is the same type of this class. The responsibility of copyToImpl is to copy the state of this class through direct access of the fields. The copyToImpl method should not use getters and setters since these may be overridden, causing the state of this class to be incompletely copied.

Specified by:

copyTo in interface Copyable

Overrides:

copyTo in class MetaTraversable

Parameters:

target - The target object to which the state of this object should be copied. If target is null, then the copyTo method will return a new instance of this class.

Returns:

The object to which the state of this object was copied. If the target was non-null, then the return value is the same as the target object that was passed in; otherwise, the return value is a new instance of this class.

copyToImpl

protected final void copyToImpl(Step copy)
