public class TempNodeCache extends Object
In some rules we need to be able to create temporary property values which are inferred from ontology constraints but not present in the ground data. This structure is used to manage a pool of such temporary nodes. It is only needed in situations where the data can not be added directly to a deductions graph due to the risk of concurrent access.
