TagScanner is an abstract superclass, subclassed to create specific scanners.
When asked to scan the tag, this class does nothing other than perform the
tag's semantic action.
Use TagScanner when you have a meta task to do like setting the BASE url for
the page when a BASE tag is encountered.
If you want to match end tags and handle special syntax between tags,
then you'll probably want to subclass
CompositeTagScanner
instead.- See Also:
