                                   throws JastorException

Create a new DatasetThing if one doesn't already exist

Parameters:

resource - Resource for object

graph - NamedGraph where resource resides

Returns:

new GraphThing

Throws:

JastorException - if resource or graph parameter is null

createGraphThing

public static GraphThing createGraphThing(java.lang.String uri,

Create a new DatasetThing if one doesn't already exist

Parameters:

uri - String representation of Resource for object

graph - NamedGraph where resource resides

Returns:

new GraphThing

Throws:

JastorException - if uri or graph parameter is null

getGraphThing
