Method Details

_execute

protected final void _execute(IntermediateResultElementSink sink,
 ExecutionContext execCxt)
                       throws ExecOpExecutionException

Description copied from class: NullaryExecutableOpBase

Implementations of this function need to execute the algorithm of this operator and send the result elements (if any) to the given sink. If an exception occurs during this process, then this exception needs to either be collected or be thrown, depending on whether BaseForExecOps.collectExceptions is set to true.

Specified by:

_execute in class NullaryExecutableOpBase

Throws:

ExecOpExecutionException

process

protected void process(SolMapsResponse response,
 IntermediateResultElementSink sink)
                throws ExecOpExecutionException

Throws:

ExecOpExecutionException

resetStats

public void resetStats()

Specified by:

resetStats in interface StatsProvider

Overrides:

resetStats in class NullaryExecutableOpBase

createStats

protected ExecutableOperatorStatsImpl createStats()

Overrides:

createStats in class BaseForExecOpRequest<ReqType extends DataRetrievalRequest,MemberType extends FederationMember>
