Description

The SchedulingTopology interface has unnecessary generic types, which are currently always set to wildcards. Example:

		private final SchedulingTopology<?, ?> schedulingTopology;


		for (SchedulingExecutionVertex<?, ?> schedulingVertex : schedulingTopology.getVertices()) {
			for (SchedulingResultPartition<?, ?> srp : schedulingVertex.getProducedResults()) {
				...
			}
		}

The above code should become:

		private final SchedulingTopology schedulingTopology;


		for (SchedulingExecutionVertex schedulingVertex : schedulingTopology.getVertices()) {
			for (SchedulingResultPartition srp : schedulingVertex.getProducedResults()) {
				...
			}
		}
