execute

Implementation for executing this pipeline.

This method is called after execWithInput potentially converts and validates the stage result type of the input parameter.

Implementations of this method can assume that input is an instance of inType. Implementations must return a StageResult object which is an instance of outType.

To consistently track the state of the currently executed job, implementations should consider to set traceableState to TraceableState.Executing with a custom implementation of ExecStateData.Executing in the body of this method, exposing more traceable metrics than the standard implementation.
