The Template Method defines a skeleton of an algorithm in an operation, and defers some steps to subclasses.

We achieve that by defining the skeleton of the checking algorithm in one operation, deferring the specific checking algorithm steps to subclasses.

The invariant steps are implemented in the abstract base class, while the variant checking algorithms have to be provided by the subclasses.

Code Block

language	java

/**
 * template method for performing a single type of checks
 * on the given @see HtmlPage.
 *
 * Prerequisite: pageToCheck has been successfully parsed,
 * prior to constructing this Checker instance.
 */
 public CheckingResultsCollector performCheck() {
    // assert prerequisite
    assert pageToCheck != null
    initResults()
    return check() // execute the actual checking algorithm
 }
