Generic Model

Spring IDE's core plugin provides interfaces with corresponding base implementations of a generic model.

Model Elements

The basic elements of this model provides the following features:

• name
• type
• unique ID
• parent-child relationships
• accessing an element by it's unique ID
• traversing the model tree via visitor pattern

The resource elements of this model provides the following features:

• Eclipse workspace resource

The source elements of this model provides the following features:

• start line number
• end line number

Accessing Model Elements

The model elements are accessed by traversing the nodes of model tree. This can be done in different ways:

1. Traversing the Model via Parent-Child Relationships

IModel model = BeansCorePlugin.getModel();
IModelElement[] projects = model.getElementChildren();
for (int i = 0; i < projects.length; i++) {
  if (project[i].getElementName().equals("TestProject")) {
    IModelElement[] configs = project[i].getElementChildren();
    for (int j = 0; j < projects.length; j++) {
      if (config[j].getElementType() == IBeansModelElementTypes.CONFIG &&
                       config[j].getElementName().equals("application-context.xml")) {
        return true;
      }
    }
  }
}
return false;

2. Traversing the Model via the Visitor Pattern

class Visitor implements IModelElementVisitor {
  public boolean visit(IModelElement element, IProgressMonitor monitor) {
    // your code here
    return true;
  }
}

IModel model = BeansCorePlugin.getModel();
model.accept(new Visitor(), new NullProgressMonitor());

3. Accessing an Element via it's unique ID

IModel model = BeansCorePlugin.getModel();
IBean bean = model.getElement("1:BeansModel|2:TestProject|3:application-context.xml|5:TestBean");
