Method Detail

isRunFirst

public boolean isRunFirst()

Description copied from interface: IServiceOptions

Return true iff the service end point is one which should always be run as early as possible within the join group (default false).

Note: This option is only obeyed when the SERVICE reference is a constant. If the SERVICE reference is a variable, then it is not possible to resolve the IServiceOptions for that SERVICE until after the query planner has locked in the join evaluation order.

setRunFirst

public void setRunFirst(boolean newValue)

isBigdataLBS

public boolean isBigdataLBS()

Description copied from interface: IServiceOptions

Return true if the remote service is known to be a bigdata service that exposes the HA load balancer servlet (default false). The default may be overridden iff the end point is known to expose the bigdata LBS pattern.
