Uses of Mapping in org.hypergraphdb

Methods in org.hypergraphdb that return Mapping

Modifier and Type	Method and Description
static <T> Mapping<HGHandle,T>	HGQuery.hg.deref(HyperGraph graph) Return a Mapping that takes a HGHandle of an atom and return its runtime against through a call to HyperGraph.get.
static Mapping<HGLink,HGHandle>	HGQuery.hg.linkProjection(int targetPosition) Return a Mapping that takes a link atom and returns a target at the given position.
static Mapping<HGLink,HGHandle>	HGQuery.hg.linkProjection(Ref<Integer> targetPosition) Return a Mapping that takes a link atom and returns a target at the given position.
static Mapping<HGHandle,HGHandle>	HGQuery.hg.targetAt(HyperGraph graph, int targetPosition) Return a Mapping that given a handle to a link will return the target (handle) at the specified target position.

Methods in org.hypergraphdb with parameters of type Mapping

Modifier and Type	Method and Description
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.
