Class AnyAtomCondition

java.lang.Object
  org.hypergraphdb.query.AnyAtomCondition

All Implemented Interfaces:

HGAtomPredicate, HGQueryCondition

public class AnyAtomCondition
extends java.lang.Object
implements HGQueryCondition, HGAtomPredicate

This condition is satisfied by any and all atoms in the HyperGraph database. That is, it is satisfied given HGHandle if and only if it is an atom in the graph.

When translated to a query alone, it will result in an enumeration of all atoms in the database.
