Golang MVCCConditionalPut Examples

Example #1

File: range_command.go Project: simonzhangsm/cockroach

// ConditionalPut sets the value for a specified key only if
// the expected value matches. If not, the return value contains
// the actual value.
func (r *Range) ConditionalPut(batch engine.Engine, ms *engine.MVCCStats, args *proto.ConditionalPutRequest, reply *proto.ConditionalPutResponse) {
	err := engine.MVCCConditionalPut(batch, ms, args.Key, args.Timestamp, args.Value, args.ExpValue, args.Txn)
	reply.SetGoError(err)
}

Example #2

File: range_command.go Project: routhcr/cockroach

// ConditionalPut sets the value for a specified key only if
// the expected value matches. If not, the return value contains
// the actual value.
func (r *Range) ConditionalPut(batch engine.Engine, ms *engine.MVCCStats, args proto.ConditionalPutRequest) (proto.ConditionalPutResponse, error) {
	var reply proto.ConditionalPutResponse

	return reply, engine.MVCCConditionalPut(batch, ms, args.Key, args.Timestamp, args.Value, args.ExpValue, args.Txn)
}
