When "drools.externaliseCanonicalModelLambda" is enabled, Predicate, Extractor and Consequence are externalized. But still lambda for binding variable exists:
e.g. CompilerTest#testStringValueOf)
public static org.drools.model.Rule rule_R() { final org.drools.model.Variable<java.lang.Integer> var_GENERATED_$pattern_Integer$1$ = D.declarationOf(java.lang.Integer.class, DomainClassesMetadata81A66AD685F7689036AAA5128956C14B.java_lang_Integer_Metadata_INSTANCE, "GENERATED_$pattern_Integer$1$"); final org.drools.model.Variable<Integer> var_$i = D.declarationOf(Integer.class, "$i"); final org.drools.model.Variable<org.drools.modelcompiler.domain.Person> var_GENERATED_$pattern_Person$1$ = D.declarationOf(org.drools.modelcompiler.domain.Person.class, DomainClassesMetadata81A66AD685F7689036AAA5128956C14B.org_drools_modelcompiler_domain_Person_Metadata_INSTANCE, "GENERATED_$pattern_Person$1$"); org.drools.model.Rule rule = D.rule("R").build(D.pattern(var_GENERATED_$pattern_Integer$1$).bind(var_$i, (java.lang.Integer _this) -> _this.intValue()), D.pattern(var_GENERATED_$pattern_Person$1$).expr("476633DA7C4638FC84A32859E0C843E6", var_$i, (_this, $i) -> org.drools.modelcompiler.util.EvaluationUtil.areNullSafeEquals(_this.getName(), (String.valueOf($i))), D.reactOn("name")), D.on(var_$i).execute(defaultpkg.P1D.LambdaConsequence1D5F4C5CA006007B1D3974ED5A5A05B6.INSTANCE)); return rule; }
See
bind(var_$i, (java.lang.Integer _this) -> _this.intValue())
Function1$Impl is instantiated by PatternDSL$PatternDefImpl.bind()
Note: The above example shows another lambda
expr("476633DA7C4638FC84A32859E0C843E6", var_$i, (_this, $i) -> org.drools.modelcompiler.util.EvaluationUtil.areNullSafeEquals(_this.getName(), (String.valueOf($i)))
This will be addressed by another JIRA.
