public class LinkScanner

extends CompositeTagScanner

Scans for the Link Tag. This is a subclass of TagScanner, and is called using a variant of the template method. If the evaluate() method returns true, that means the given string contains an image tag. Extraction is done by the scan method thereafter by the user of this class.
