AnnotationChecker

abstract class AnnotationChecker extends AnyRef

An additional checker for annotations on types. Typically these are registered by compiler plugins with the addAnnotationChecker method.

Abstract Value Members

  1. abstract def annotationsConform(tpe1: Type, tpe2: Type): Boolean

    Check the annotations on two types conform.

  6. def adaptAnnotations(tree: Tree, mode: Int, pt: Type): Tree

    Adapt a tree that has an annotated type to the given type tp, taking into account the given mode (see method adapt in trait Typers).

    Adapt a tree that has an annotated type to the given type tp, taking into account the given mode (see method adapt in trait Typers). An implementation cannot rely on canAdaptAnnotations being called before. If the implementing class cannot do the adaptiong, it should return the tree unchanged.

  7. def adaptBoundsToAnnotations(bounds: List[TypeBounds], tparams: List[Symbol], targs: List[Type]): List[TypeBounds]

    Refine the bounds on type parameters to the given type arguments.

  8. def adaptTypeOfReturn(tree: Tree, pt: Type, default: ⇒ Type): Type

    Adapt the type of a return expression.

    Adapt the type of a return expression. The decision of an annotation checker whether the type should be adapted is based on the type of the expression which is returned, as well as the result type of the method (pt). By default, this method simply returns the passed default type.

  9. def addAnnotations(tree: Tree, tpe: Type): Type

    Modify the type that has thus far been inferred for a tree.

    Modify the type that has thus far been inferred for a tree. All this should do is add annotations.

  10. def annotationsGlb(tp: Type, ts: List[Type]): Type

    Refine the computed greatest lower bound of a list of types.

    Refine the computed greatest lower bound of a list of types. All this should do is add annotations.

  11. def annotationsLub(tp: Type, ts: List[Type]): Type

    Refine the computed least upper bound of a list of types.

    Refine the computed least upper bound of a list of types. All this should do is add annotations.

  13. def canAdaptAnnotations(tree: Tree, mode: Int, pt: Type): Boolean

    Decide whether this annotation checker can adapt a tree that has an annotated type to the given type tp, taking into account the given mode (see method adapt in trait Typers).
