  • Declaration

    struct BaseClass;

    • Declaration

      bool fillVtbl(ClassDeclaration cd, FuncDeclarations* vtbl, int newinstance);

      Fill in vtbl[] for base class based on member functions of class cd.

      Input: vtbl if !=NULL, fill it in newinstance !=0 means all entries must be filled in by members of cd, not members of any base classes of cd.

      Return Value

      true if any entries were filled in by members of cd (not exclusively by base classes)

  • Declaration

    class ClassDeclaration: dmd.aggregate.AggregateDeclaration;

    • Declaration

      bool stack;

      true if this is a scope class

    • Declaration

      int cppDtorVtblIndex;

      if this is a C++ class, this is the slot reserved for the virtual destructor

    • Declaration

      Baseok baseok;

      set the progress of base classes resolving

    • Declaration

      ObjcClassDeclaration objc;

      Data for a class declaration that is needed for the Objective-C integration.

    • Declaration

      final pure nothrow @nogc bool isBaseOf2(ClassDeclaration cd);

      Determine if 'this' is a base class of cd. This is used to detect circular inheritance only.

    • Declaration

      pure nothrow @nogc bool isBaseOf(ClassDeclaration cd, int* poffset);

      Determine if 'this' is a base class of cd.

    • Declaration

      final const bool isBaseInfoComplete();

      Determine if 'this' has complete base class information. This is used to detect forward references in covariant overloads.

    • Declaration

      final ClassDeclaration searchBase(Identifier ident);

      Search base classes in depth-first, left-to-right order for a class or interface named 'ident'. Stops at first found. Does not look for additional matches.

      Parameters

      Identifier ident

      identifier to search for

      Return Value

      ClassDeclaration if found, null if not

    • Declaration

      final bool hasMonitor();

      Return Value

      true if there's a __monitor field

    • Declaration

      final FuncDeclaration findFunc(Identifier ident, TypeFunction tf);

      Find virtual function matching identifier and type. Used to build virtual function tables for interface implementations.

      Parameters

      Identifier ident

      function's identifier

      TypeFunction tf

      function's type

      Return Value

      function symbol if found, null if not

      Errors: prints error message if more than one match

    • Declaration

      final const bool isCOMclass();

    • Declaration

      final bool isAbstract();

    • Declaration

      const int vtblOffset();

      Determine if slot 0 of the vtbl[] is reserved for something else. For class objects, yes, this is where the classinfo ptr goes. For COM interfaces, no. For non-COM interfaces, yes, this is where the Interface ptr goes.

      Return Value

      0 vtbl[0] is first virtual function pointer 1 vtbl[0] is classinfo/interfaceinfo pointer

    • Declaration

      const const(char)* kind();

    • Declaration

      final void addLocalClass(ClassDeclarations* aclasses);

  • Declaration

    class InterfaceDeclaration: dmd.dclass.ClassDeclaration;

    • Declaration

      pure nothrow @nogc bool isBaseOf(ClassDeclaration cd, int* poffset);

      Determine if 'this' is a base class of cd. (Actually, if it is an interface supported by cd)

      Output: *poffset offset to start of class OFFSET_RUNTIME must determine offset at runtime

      Return Value

      false not a base true is a base

    • Declaration

      const const(char)* kind();

    • Declaration

      const int vtblOffset();

      Determine if slot 0 of the vtbl[] is reserved for something else. For class objects, yes, this is where the ClassInfo ptr goes. For COM interfaces, no. For non-COM interfaces, yes, this is where the Interface ptr goes.
