Abstraction for providing data at view-time by SAXing events.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`boolean`	`isCacheable(Site site, Page page)`	Returns true if this `InputData` is cacheable for the current site and if possible page.
`default boolean`	`shouldBeCached(Site site, Page page)`	Returns true if the resulting SAX events should be actually stored in the central `PageElementCache`. It may be useful to return false for some InputData managing their own cache and don't wanting to waste space in the central cache. This method is only called if `isCacheable(Site, Page)` returns true.
`void`	`toSAX(ContentHandler handler)`	Generates SAX events for providing data.

  - toSAX
```
void toSAX(ContentHandler handler)
    throws SAXException,
           ProcessingException
```
    Generates SAX events for providing data.
