public interface PipelineOperator<T extends LogicalPort>
extends LogicalOperator

Mix-in interface to be implemented by some operators. By convention, operators that define a single input and single output of the same type should implement this interface since it make facilitate higher-level composition frameworks. Note that the core DR engine does not currently have any special handling for operators that implement this interface.
