Class BaseInfGraph.InfCapabilities

java.lang.Object
  com.hp.hpl.jena.graph.impl.AllCapabilities
      com.hp.hpl.jena.reasoner.BaseInfGraph.InfCapabilities

All Implemented Interfaces:

Capabilities

Direct Known Subclasses:

BaseInfGraph.InfFindSafeCapabilities

Enclosing class:

BaseInfGraph

public static class BaseInfGraph.InfCapabilities
extends com.hp.hpl.jena.graph.impl.AllCapabilities

An InfCapabilities notes that size may not be accurate, and some triples may be irremovable. TODO accomodate the properties of the base graph, too.

Constructor Summary

BaseInfGraph.InfCapabilities()

Method Summary

boolean	deleteAllowed(boolean every) Answer true if Graph::delete() can be used to remove at least some triples from the graph.
boolean	findContractSafe() Answer true if the find() contract on the associated graph is "safe", ie, can be used safely by the pretty-printer (we'll tighten up that definition).
boolean	iteratorRemoveAllowed() Answer true iff the iterators returned from find support the .remove() operation.
boolean	sizeAccurate() Answer true iff Graph::size() is accurate.
