Examples of org.postgresql.largeobject.LargeObjectManager.open()

org.postgresql.largeobject.LargeObjectManager.open()

This method assumes that READ and WRITE access is required (the default). @param oid of large object @return LargeObject instance providing access to the object @exception SQLException on error @deprecated As of 8.3, replaced by {@link #open(long)}
