DatasetGraphAccessor

Hi guys,
I need an information about DatasetGraphAccessor.

When I use this interface to access a graph contained in a remote dataset,
does it downloads all the triples immediately or are they downloaded
on-demand (e.g. calling the method find())?

Thank you in advance.

See the source code :-)

Dataset[Graph]Accessor is the SPARQL Graph Store Protocol - it only does 
GET, PUT, POST and DELETE whole graph or the local equivalent.

If you GET a graph, it is a local copy of the whole graph.

You may be interested in a proposed combined SPARQL API:
