FeatureHolder
. This is a filter
which all Feature
s immediately contained by this FeatureHolder
will match. It need not directly match their child features, but it can (and should!) provide
information about them using FeatureFilter.OnlyChildren
filters. In cases where there
is no feature hierarchy, this can be indicated by including FeatureFilter.leaf
in
the schema filter.
For the truly non-informative case, it is possible to return FeatureFilter.all
. However,
it is almost always possible to provide slightly more information that this. For example, Sequence
objects should, at a minimum, return FeatureFilter.top_level
. Feature
objects
should, as a minimum, return FeatureFilter.ByParent(new FeatureFilter.ByFeature(this))
.
