Interface Model

All Known Implementing Classes:

SesameModel

public interface Model

A gateway between an RDF data store and the native Ripple environment of stacks and streams. Most of the things you can do in Ripple involve a ModelConnection, which provides transactional access to a Model. Native Ripple values are totally ordered in a Model, and each one maps to exactly one RDF resource.

Method Detail

createConnection

ModelConnection createConnection()
                                 throws RippleException

Returns:

a new, transactional connection to this model

RippleException - if creation of the connection fails

createConnection

ModelConnection createConnection(RDFDiffSink listener)
                                 throws RippleException

Parameters:

listener - a handler for RDF diffs of data added or removed from the model through the returned connection

Returns:

a new, transactional connection to this model, to which the given listener is attached

Throws:

RippleException - if creation of the connection fails

getSpecialValues

SpecialValueMap getSpecialValues()

Returns:

a mapping of RDF space into Ripple space

shutDown

void shutDown()
              throws RippleException
