/**
 * A source container type represents a kind of container of source code.
 * For example, a source container type may be a project or a directory. A specific
 * project or directory is represented by an instance of a source container type,
 * which is called a source container (<code>ISourceContainer</code>).
 * <p>
 * A source container type is contributed via the <code>sourceContainerTypes</code>
 * extension point, providing a delegate to the work specific to the contributed
 * type. Following is an example contribution.
 * <pre>
 * &lt;extension point=&quot;org.eclipse.debug.core.sourceContainerTypes&quot;&gt;
 * 	&lt;sourceContainerType
 * 		name=&quot;Project&quot;
 * 		class=&quot;org.eclipse.debug.internal.core.sourcelookup.containers.ProjectSourceContainerType&quot;
 * 		id=&quot;org.eclipse.debug.core.containerType.project&quot;
 * 		description=&quot;A project in the workspace&quot;&gt;
 * 	&lt;/sourceContainerType&gt;
 * &lt;/extension&gt;
 * </pre>
 * </p>
 * <p>
 * Clients are not intended to implement this interface. Instead, clients contributing
 * a source container type implement {@link org.eclipse.debug.core.sourcelookup.ISourceContainerTypeDelegate}.
 * </p>
