with-transaction clj macro

(with-transaction dataset rw-type & body)

Custom statement. Syntax: (with-transaction ReadWrite/[READ|WRITE] db ... body ...) The body is wrapped in a transaction of the supplied type (read or write) that works inside the supplied Jena Dataset. If an exception is thrown from whithin the body, the transaction is aborted and the exception is thrown. Otherwise the last expression in the body is returned. WARNING: Do not return the database or its contents (e.g. Dataset, Model) from this statement or the database will escape the scope of the transaction throwing an exception. WARNING2: Beware when creating a lazy sequence of the resultset. You must consume it fully before trying to add new triples into the triplestore. Use doall if needed.
