levels of abstractions

one level of abstraction :



public static String renderPageWithSetupsAndTeardowns(
PageData pageData, boolean isSuite) throws Exception {
if (isTestPage(pageData))
includeSetupAndTeardownPages(pageData, isSuite);
return pageData.getHtml();
}





second level of abstraction : 


private void includeSetupAndTeardownPages(pageData, isSuite) throws Exception {
includeSetupPages(isSuite);
includePageContent();
includeTeardownPages();
updatePageContent();
}




third level of abstraction : 

private void includeSetupPages() throws Exception {
if (isSuite)
   includeSuiteSetupPage();
includeSetupPage();
}



forth level of absaction : 


private void includeSuiteTeardownPage() throws Exception {  
   include(SuiteResponder.SUITE_TEARDOWN_NAME, "-teardown");
}


fifth level of abstaction : 

private void include(String pageName, String arg) throws Exception {
   WikiPage inheritedPage = findInheritedPage(pageName);
   if (inheritedPage != null) {
   String pagePathName = getPathNameForPage(inheritedPage);
   buildIncludeDirective(pagePathName, arg);
}
}
