Chapter 11. Seam Refactoring Tools

The goal of Seam components refactoring is to make system-wide code changes without affecting the behavior of the program. The Seam module of JBoss Tools provides assistance in easily code refactoring.

Starting from Jboss Tools M4 refactoring functionality became also available for managed beans, method and properties used in ELs. Thus now Seam refactoring tools include the next refactoring operations:

Refactoring commands are available from the context menus of several views and editors and use a standard Eclipse refactoring wizard. For details, see "Using the Refactoring Wizard" later in this chapter.

Note:

Seam refactoring could be only performed in the file that is not marked as Read only in its properties.

11.1. Using the Refactorinig Wizard

This wizard is opened always when the user clicks the Rename Seam Component, Rename Seam Context Variable or Rename command in any of the views/editors mentioned later in this chapter.

In the Seam Components name field you should enter a new name of the component, then click Next and follow the next wizard steps:

Figure 11.3. Navigating Between the Differences

As you see, when performing a refactoring operation, you can preview all of the changes resulting from a refactoring action before you choose to carry them out.

The view represents two windows: one with the original source code and the other with refactored one.

With the help of , , , buttons you can quickly navigate between the differences in the code. If you don't agree with some changes you can't undo them but you can remove the class from the list of classes that need refactoring.

To apply the changes click Finish.

Renaming the selected seam component corrects all references to the component (also in other files in the project). Renaming a type doesn't allow to rename similarly named variables and methods.

11.2. Renaming Seam Components

Renaming a Seam component could be performed in the:

11.2.1. Renaming Seam Components in the Java Editor

If you want to rename certain seam component using Java editor, first of all it's necessary to open it. If you don't know, where the seam component is declared, use Open Seam Components icon.

To rename a Seam component in the Java editor it's necessary to select the component, left click the file and then select Seam Refactor > Rename Seam Component.
