Methods ​

apply(...mixins: IMixin[]): MixinApplicator // chainabledef apply(self, mixins: IMixin) -> MixinApplicatorpublic MixinApplicator apply(IMixin mixins)public MixinApplicator Apply(IMixin mixins)func Apply(Mixins IMixin) MixinApplicator#
Applies a mixin to selected constructs.
requireAll(): MixinApplicator // chainabledef require_all(self, ) -> MixinApplicatorpublic MixinApplicator requireAll()public MixinApplicator RequireAll()func RequireAll() MixinApplicator#
Requires all selected constructs to support the applied mixins.

Will only check for future call of apply(). Set this before calling apply() to take effect.

example
ts
Mixins.of(scope)
  .requireAll()
  .apply(new MyMixin());
requireAny(): MixinApplicator // chainabledef require_any(self, ) -> MixinApplicatorpublic MixinApplicator requireAny()public MixinApplicator RequireAny()func RequireAny() MixinApplicator#
Requires at least one mixin to be successfully applied.

Will only check for future call of apply(). Set this before calling apply() to take effect.

example
ts
Mixins.of(scope)
  .requireAny()
  .apply(new MyMixin());
