Class ApplyTraitsOrError

java.lang.Object

org.ek9lang.compiler.common.RuleSupport

org.ek9lang.compiler.phase2.ApplyTraitsOrError

All Implemented Interfaces:

BiConsumer<EK9Parser.TraitsListContext, AggregateWithTraitsSymbol>

final class ApplyTraitsOrError
extends RuleSupport
implements BiConsumer<EK9Parser.TraitsListContext, AggregateWithTraitsSymbol>

Resolves each trait in a 'traitsList' (checking it is a suitable CLASS_TRAIT to extend) and adds it to the supplied aggregate. A null traitsList is tolerated (nothing to add).

Centralises the resolve-each-trait-and-add loop that was otherwise repeated verbatim by every construct that can have traits (trait declarations, dynamic classes, class declarations).
