| /** |
| * Represents a section of properties for a given input. |
| * <p> |
| * The lifecycle of an ISection is as follows: |
| * <ul> |
| * <li><code>ISection.createControls()</code></li> |
| * <li><code>ISection.setInput()</code></li> |
| * <li><code>ISection.aboutToBeShown()</code></li> |
| * <li><code>ISection.refresh()</code></li> |
| * <li><code>ISection.aboutToBeHidden()</code></li> |
| * <li><code>ISection.dispose()</code></li> |
| * </ul> |
| * </p> |
| * <p> |
| * Implementors of this class should be aware that a section instance might be |
| * reused for different input objects (as long as they are valid section |
| * inputs). It means that <code>ISection.setInput</code> can be called at any |
| * time between <code>ISection.createControls</code> and |
| * <code>ISection.dispose</code>. |
| * </p> |
| * <p> |
| * When an input change event occurs, such as a tab selection or a workbench |
| * selection change, an ISection is sent: |
| * <ul> |
| * <li><code>ISection.setInput()</code></li> |
| * <li><code>ISection.refresh()</code></li> |
| * </ul> |
| * </p> |
| * <p> |
| * When an part activation event occurs, such as the contributor part activation |
| * event, an ISection is sent: |
| * <ul> |
| * <li><code>ISection.setInput()</code></li> |
| * <li><code>ISection.aboutToBeShown()</code></li> |
| * <li><code>ISection.refresh()</code></li> |
| * <li><code>ISection.setInput()</code></li> |
| * <li><code>ISection.refresh()</code></li> |
| * </ul> |
| * This is because both a tab selection event and an input selection event have |
| * occurred. |
| * </p> |
| * <p> |
| * This interface should not be extended or implemented. New section instances |
| * should be created using <code>AbstractPropertySection</code>. |
