Method Summary

Modifier and Type	Method and Description
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.
