Class Summary

Class	Description
AnalyzedQuery<SearchResult>	A query object that holds information collected during the compilation process.
And	Represents the conjunction operator of a query condition.
AnyAtomCondition	This condition is satisfied by any and all atoms in the HyperGraph database.
ArityCondition	The ArityCondition is a simply predicate condition that checks the arity (i.e.
AtomPartCondition	A condition that constraints the value of a component of a composite typed atom.
AtomPartRegExPredicate	A predicate that constrains the value of a component of a composite typed atom using a regular expression.
AtomProjectionCondition	An AtomProjectionCondition will yield all atoms that are projections along a certain dimension of a given base atom set.
AtomRegExPredicate	Base class for matching string values using a regular expression.
AtomTypeCondition	An AtomTypeCondition examines the type of a given atom and evaluates to true or false depending on whether the type of the atom matches exactly (i.e.
AtomValueCondition	The AtomValueCondition represents a query condition on the atom value.
AtomValueRegExPredicate	A predicate that constrains the value of an atom using a regular expression.
BFSCondition	The breadth-first search variant of a TraversalCondition.
DFSCondition	The depth-first search variant of a TraversalCondition.
DisconnectedPredicate	A predicate that returns true if the incidence set of a given atom is empty and false otherwise.
HGQueryConfiguration	Holds a set of configuration settings for the query sub-system of a HyperGraph instance.
IncidentCondition	The IncidentCondition specifies that a search result atom should be a member of the incidence set of a given atom.
IndexCondition<Key,Value>
IndexedPartCondition
IsCondition	An "identity" condition that evaluates to true for a specific handle.
LinkCondition	A LinkCondition constraints the query result set to links pointing to a target set of atoms.
MapCondition
Not	A generic negating HGQueryCondition.
Nothing	This condition represents the negation of everything.
Or	Represents the disjunction operator of a query condition.
OrderedLinkCondition	A OrderedLinkCondition constraints the query result set to ordered links pointing to a target set of atoms.
PositionedIncidentCondition	A PositionedLinkCondition constraints the query result set to links pointing to a target atom positioned within a predetermined range in the link tuple.
QueryCompile	A controller-type of class that maintains context during the query compilation process.
SimpleValueCondition	Basic class for conditions examining individual primitive values.
SubgraphContainsCondition
SubgraphMemberCondition
SubsumedCondition	The SubsumedCondition examines a given atom and is satisfied if that atom is subsumed by the atom specified in the condition.
SubsumesCondition	The SubsumesCondition examines a given atom and is satisfied if that atom subsumes the atom specified in the condition.
TargetCondition	A query condition that constraints the result set to atoms that are targets to a specific link.
TraversalCondition	A condition that gets translated into a graph traversal.
TypedValueCondition	This is a HGQueryCondition that constrains the value of an atom as well as its type.
