  8. object Function1

    An extractor for unary function types arg => res

  9. object HasMember

    An extractor for types of the form ? { name: ? }

  10. object HasMethodMatching

    An extractor for types of the form ? { name: (? >: argtpe <: Any*)restp }

  11. object ImplicitNotFoundMsg

  12. val NoImplicitInfo: Analyzer.ImplicitInfo

    A sentinel indicating no implicit was found

  13. lazy val SearchFailure: Analyzer.SearchResult

  14. def allViewsFrom(tp: Global.Type, context: Analyzer.Context, tpars: List[Global.Symbol]): List[(Analyzer.SearchResult, List[Global.TypeConstraint])]

    Find all views from type tp (in which tpars are free)

    Find all views from type tp (in which tpars are free)

    Note that the trees in the search results in the returned list share the same type variables. Ignore their constr field! The list of type constraints returned along with each tree specifies the constraints that must be met by the corresponding type parameter in tpars (for the returned implicit view to be valid).

  27. def inferImplicit(tree: Global.Tree, pt: Global.Type, reportAmbiguous: Boolean, isView: Boolean, context: Analyzer.Context, saveAmbiguousDivergent: Boolean, pos: Global.Position): Analyzer.SearchResult

    Search for an implicit value.

    Search for an implicit value. See the comment on result at the end of class ImplicitSearch for more info how the search is conducted.

    tree

    The tree for which the implicit needs to be inserted. (the inference might instantiate some of the undetermined type parameters of that tree.

    pt

    The expected type of the implicit.

    reportAmbiguous

    Should ambiguous implicit errors be reported? False iff we search for a view to find out whether one type is coercible to another.

    isView

    We are looking for a view

    context

    The current context

    saveAmbiguousDivergent

    False if any divergent/ambiguous errors should be ignored after implicits search, true if they should be reported (used in further typechecking).

    pos

    Position that is should be used for tracing and error reporting (useful when we infer synthetic stuff and pass EmptyTree in the tree argument) If it's set NoPosition, then position-based services will use tree.pos

    returns

    A search result
