I guess giving the parameter a more descriptive name would do the trick ``` /** * Convert the failure into an {@link ExceptionHistoryEntry}. * * @param findExecutionFn Function that looks up additional information on the {@link * ExecutionVertexID}, which can be used for constructing the {@link ExceptionHistoryEntry}. * @return The {@link ExceptionHistoryEntry} derived for this failure. */ public abstract ExceptionHistoryEntry toExceptionHistoryEntry( Function<ExecutionVertexID, Execution> findExecutionFn); ``` One additional thought about naming getters, it's good to distinguish between getters that return an actual value (`getXXX`) and getters that return an optional (`findXXX`). -- This is an automated message from the Apache Git Service.
