Class UrlAwareParser

      wt.htmlutil.UrlAwareParser

Direct Known Subclasses:

UrlAwareTextFormatter, UrlLister, WWWTester

public abstract class UrlAwareParser

extends TextParser

Implements TextParser's parseWord() method to search a stream word by word for URLs. UrlAwareParser is itself an abstract class, however, since there is no obvious default behavior for how detection/non-detection of an URL should be handled. Hence the abstract handleUrl() and handleNotUrl() methods.

Field Summary
