A class responsible for extract refactoring. Use the
Refactoring.Extracting class to create the extract
manager for a symbol which you want to extract. Configure the extract refactoring by changing
ExtractSource and
ExtractTarget. Invoke the refactoring with RefactorManager.refactor().
Review refactoring results by inspecting
ExtractSource and
ExtractTarget.
// Creates extract refactor manager.
ExtractManager extractManager = Refactoring.Extracting.createExtractManager(symbols);
if (extractManager != null)
{
// A session has to be started before refactoring.
SessionManager sessionManager = SessionManager.getInstance();
sessionManager.createSession("Extract Refactor Symbols");
// We may control the extract refactor result by modifying extract target.
ExtractTarget extractTarget = extractManager.getExtractTarget();
// Create a namespace to which we are going to refactor.
Project project = Project.getProject(symbols[0]);
Package package1 = project.getElementsFactory().createPackageInstance();
package1.setOwner(project.getModel());
// Set the namespace to which the extract result will go.
extractTarget.setTargetNamespace(package1);
// Choose target diagram type from allowed diagram types if the default type does not suite.
List allowedTargetDiagramTypes = extractTarget.getAllowedTargetDiagramTypes();
extractTarget.setTargetDiagramType(allowedTargetDiagramTypes.get(0));
// Modify reference names which link the extract refactor source to the target.
List references = extractTarget.getReferences();

ExtractReference reference = references.get(i);
reference.setName(Integer.toString(i));
}
