Class DataFlow::LegacyFlowStep

A data flow edge that is only seen by the old, deprecated data flow library.

This class is typically used when a step has been replaced by a flow summary. Since the old data flow library does not support flow summaries, such a step should remain as a legacy step, until the old data flow library can be removed.

Note: For performance reasons, all subclasses of this class should be part of the standard library. Override Configuration::isAdditionalFlowStep for analysis-specific flow steps.
