36 * A filter processes blocks of text looking for certain patterns (such as URLs or keywords from a list)
39 * Each hotspot has a type identifier associated with it ( such as a link or a highlighted section ),
40 * and an action. When the user performs some activity such as a mouse-click in a hotspot area ( the exact
41 * action will depend on what is displaying the block of text which the filter is processing ), the hotspot's
42 * activate() method should be called. Depending on the type of hotspot this will trigger a suitable response.
44 * For example, if a hotspot represents a URL then a suitable action would be opening that URL in a web browser.
45 * Hotspots may have more than one action, in which case the list of actions can be obtained using the
49 * Subclasses must reimplement the process() method to examine a block of text and identify sections of interest.
50 * When processing the text they should create instances of Filter::HotSpot subclasses for sections of interest
