Look for references to IResourceProxyVisitor, e.g. from cdt.ui ToggleSourceAndHeaderAction,
with IContainer being the project:

	/**
	 * Find a file in the given resource container for the given basename.
	 * 
	 * @param container
	 * @param basename
	 * @return a matching {@link IFile} or <code>null</code>, if no matching file was found
	 */
	private IFile findInContainer(IContainer container, final String basename) {
		final IFile[] result= { null };
		IResourceProxyVisitor visitor= new IResourceProxyVisitor() {
			public boolean visit(IResourceProxy proxy) throws CoreException {
				if (result[0] != null) {
					return false;
				}
				if (!proxy.isAccessible()) {
					return false;
				}
				if (proxy.getType() == IResource.FILE && proxy.getName().equals(basename)) {
					result[0]= (IFile)proxy.requestResource();
					return false;
				}
				return true;
			}};
		try {
			container.accept(visitor, 0);
		} catch (CoreException exc) {
			// ignore
		}
		return result[0];
	}
