Method Summary

Methods

Modifier and Type	Method and Description
long	getBatchResolveNanos() Return the time required to batch resolve any unknown RDF Values against the dictionary indices before executing the corresponding SPARQL UPDATE operation within a SPARQL UPDATE request that has multiple operations (batch resolution must be performed before each UPDATE operation in case an RDF Value not known at the time that the SPARQL UPDATE parser was run has since become defined through a side-effect of a previous SPARQL UPDATE request within the scope of the same connection).
Throwable	getCause() The cause iff an error occurred and otherwise null.
long	getConnectionFlushNanos() Return the time required to flush the sail connection before executing the corresponding SPARQL UPDATE operation within a SPARQL UPDATE request that has multiple operations (the sail connection is flushed before each operation except the first).
SPARQLUpdateEvent.DeleteInsertWhereStats	getDeleteInsertWhereStats() Return statistics associated with the processing of a DELETE/INSERT WHERE operation (and otherwise null).
long	getElapsedNanos() Return the elapsed runtime for that update operation in nanoseconds.
Update	getUpdate() Return the update operation.
