Examples of org.openrdf.sail.SailConnection.addStatement()

org.openrdf.sail.SailConnection.addStatement()
Adds a statement to the store. @param subj The subject of the statement to add. @param pred The predicate of the statement to add. @param obj The object of the statement to add. @param contexts The context(s) to add the statement to. Note that this parameter is a vararg and as such is optional. If no contexts are specified, a context-less statement will be added. @throws StoreException If the statement could not be added.
