  • AliasThis

    Declaration

    class AliasThis: dmd.dsymbol.Dsymbol;

    alias ident this;

    • sym

      Declaration

      Dsymbol sym;

      The symbol this alias this resolves to

    • isDeprecated_

      Declaration

      bool isDeprecated_;

      Whether this alias this is deprecated or not

  • checkDeprecatedAliasThis

    Declaration

    bool checkDeprecatedAliasThis(AliasThis at, ref const Loc loc, Scope* sc);

    Check if an alias this is deprecated

    Discussion

    Usually one would use expression.checkDeprecated(scope, aliasthis) to check if expression uses a deprecated aliasthis, but this calls toPrettyChars which lead to the following message: "Deprecation: alias this fullyqualified.aggregate.__anonymous is deprecated"

    Parameters

    AliasThis at

    The AliasThis object to check

    Loc loc

    Loc of the expression triggering the access to at

    Scope* sc

    Scope of the expression (deprecations do not trigger in deprecated scopes)

    Return Value

    Whether the alias this was reported as deprecated.

  • isRecursiveAliasThis

    Declaration

    bool isRecursiveAliasThis(ref Type att, Type t);

    Check and set 'att' if 't' is a recursive 'alias this' type

    Parameters

    Type att

    type reference used to detect recursion

    Type t

    'alias this' type

    Return Value

    Whether the 'alias this' is recursive or not
