Dataquay::CacheingPropertyObject Class Reference

CacheingPropertyObject is a helper class for managing RDF properties of an object URI – that is, triples that share a common subject and possibly a common prefix for the predicate, and that have only one value for each subject-predicate combination. More...

Detailed Description

CacheingPropertyObject is a helper class for managing RDF properties of an object URI – that is, triples that share a common subject and possibly a common prefix for the predicate, and that have only one value for each subject-predicate combination.

This class caches results from the datastore and so may be faster than PropertyObject, but it can only be used in contexts where it is known that no other agent may be modifying the same set of properties. Its set of available functions is more limited than PropertyObject also: it has no Transaction-based functions.

See PropertyObject for individual method documentation.
