Classes in org.hypergraphdb.query used by org.hypergraphdb

Class and Description
And Represents the conjunction operator of a query condition.
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.
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.
ComparisonOperator Type safe enum for comparison operators equals, less than etc.
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.
HGAtomPredicate This interface defines a predicate of a single atom.
HGQueryCondition The interface defines a HyperGraph query condition.
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.
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.
Not A generic negating HGQueryCondition.
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.
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.
