ReferenceReductionRule (MPS.Core (JetBrains MPS 2019.1.0))

All Superinterfaces:

TemplateRule, TemplateRuleForConcept, TemplateRuleWithCondition

All Known Implementing Classes:

ReferenceReductionRuleBase, RefReductionRuleInterpreted
```
public interface ReferenceReductionRule
extends TemplateRuleWithCondition, TemplateRuleForConcept
```
use of TemplateRuleForConcept is dubious, just investigating if it makes any reasonable sense. Now we use if to reuse FastRuleFinder, but it doesn't look like anything valuable.

Since:

2017.3
