XFF is an experimental format, and both the format and the APIs in this package may change in the future.
The main class in this package is XFFFeatureSetHandler
,
which is intended as a content handler for XFF featureSet
elements. By default, this class handles the XFF feature
and strandedFeature
types. Any other feature types
are treated as one of these. It is, however, possible to plug in
additional handlers to cope with sub-types of feature
.
The only detail type recognized is xff:prop
-- all others
are silently ignored. But again, it is easy to plug in extra StAX
handlers for other detail types.
When writing a handler, for a new feature type, you will normally want
to sub-class the existing FeatureHandler
or
StrandedFeatureHanlder
classes.
