implements SelectFSs<T>

Collection of builder style methods to specify selection of FSs from indexes shift handled in this routine Comment codes: AI = implies AnnotationIndex Iterator varieties and impl bounded? type order not unambig? strict? skipEq Priority? Needed? no coveredBy covering sameas for not-bounded, - ignore strict and skipEq -- except: preceding implies skipping annotations whose end > positioning begin - order-not-needed only applies if iicp size > 1 - unambig ==> use Subiterator -- subiterator wraps: according to typePriority and order-not-needed - no Type Priority - need to pass in as arg to fsIterator_multiple_indexes == if no type priority, need to prevent rattling off the == type while compare is equal == affects both FsIterator_aggregation_common and FsIterator_subtypes_ordered for 3 other boundings: - use subiterator, pass in strict and skipeq finish this javadoc comment edit T extends FeatureStructure, not TOP, because of ref from FSIndex which uses FeatureStructure for backwards compatibility

offset - the offset adjustment, positive or negative.

Returns:

the selected element or null
