Uses of TwoWayIterator in org.hypergraphdb

Subinterfaces of TwoWayIterator in org.hypergraphdb

interface	HGRandomAccessResult<ValueType> A HGRandomAccessResult is a search result that is based on some kind of cursor that allows immediate positioning on some result value, if it exists.
interface	HGSearchResult<T> Represents the result set of a HyperGraph query.

RSCombiner<T>

Classes in org.hypergraphdb.query.impl that implement TwoWayIterator

class	FilteredResultSet<T> Filter a result set through a predicate.
class	HandleArrayResultSet Implements a HGSearchResult comprising the atoms in a given HGHandle array.
class	InMemoryIntersectionResult<T>
class	LinkTargetsResultSet This is the same as HandleArrayResultSet, but it uses a loaded link atom instance instead of a HGHandle.
class	MappedResult A MappedResult is a HGSearchResult with an applied transformation to each of its elements.
class	PipedResult A piped query result takes the output of a query, in the form of a HGSearchResult instance and uses it as input to a "pipe" query.
class	ProjectionAtomResultSet
class	SortedIntersectionResult<T> Combines two ordered result sets into a (ordered) result representing their set theoretical intersection.
class	TraversalResult TraversalResult wraps a graph HGTraversal as a query HGSearchResult.
class	UnionResult Combines two result set into a result representing their set theoretic union.
class	ZigZagIntersectionResult<T> The ZigZagIntersectionResult operates on two sorted, random access result sets.

Classes in org.hypergraphdb.storage that implement TwoWayIterator

class	IndexResultSet<T> An IndexResultSet is based on a cursor over an indexed set of values.
class	KeyScanResultSet<T> Scans the key elements of an index.
class	SingleKeyResultSet<T> Implements a BerkeleyDB Cursor based result set that iterates over all duplicates of a given key.
class	SingleValueResultSet<T> A result set based on a BerkeleyDB secondary cursor.
