| /** |
| * Interface of a buildpath container. A buildpath container provides a way to |
| * indirectly reference a set of buildpath entries through a buildpath entry of |
| * kind <code>BPE_CONTAINER</code>. Typically, a buildpath container can be used |
| * to describe a complex library composed of multiple archives or projects, |
| * considering also that containers can map to different set of entries on each |
| * project, in other words, several projects can reference the same generic |
| * container path, but have each of them actually bound to a different container |
| * object. |
| * <p> |
| * The set of entries associated with a buildpath container may contain any of |
| * the following: |
| * <ul> |
| * <li>library entries (<code>BPE_LIBRARY</code>)</li> |
| * <li>project entries (<code>BPE_PROJECT</code>)</li> |
| * </ul> |
| * In particular, a buildpath container can neither reference further buildpath |
| * containers or buildpath variables. |
| * <p> |
| * buildpath container values are persisted locally to the workspace, but are |
| * not preserved from a session to another. It is thus highly recommended to |
| * register a <code>buildpathContainerInitializer</code> for each referenced |
| * container (through the extension point |
| * "org.eclipse.dltk.core.buildpathContainerInitializer"). |
| * <p> |
