Uses of HGQueryCondition in org.hypergraphdb

Methods in org.hypergraphdb that return HGQueryCondition

Modifier and Type	Method and Description
static HGQueryCondition	HGQuery.hg.all() Return a condition that will yield all atoms in the graph.
static HGQueryCondition	HGQuery.hg.apply(Mapping<?,?> m, HGQueryCondition c) Return a "condition" that transforms the result set by applying an arbitrary Mapping to each element.
static HGQueryCondition	HGQuery.hg.deref(HyperGraph graph, HGQueryCondition condition) Short for hg.apply(hg.deref(graph), condition) - assuming the condition parameter yields a result set of HGHandles, the returned condition will yield a result set of atoms loaded from the graph parameter.
static HGQueryCondition	HGQuery.hg.guessUniquenessCondition(HyperGraph graph, Object instance) Construct a HGQueryCondition that uniquely identifies an atom based on the passed in Object instance.
