public interface SourceOperator<T extends LogicalPort>
extends LogicalOperator
Mix-in interface to be implemented by some operators. By convention, operators that define a
single output and zero inputs should 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.
