dmd.dclass

Compiler implementation of the D programming language.

Source dclass.d

struct BaseClass;
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.

Returns:
true if any entries were filled in by members of cd (not exclusively by base classes)
class ClassDeclaration: dmd.aggregate.AggregateDeclaration;
bool stack;
true if this is a scope class
int cppDtorVtblIndex;
if this is a C++ class, this is the slot reserved for the virtual destructor
Baseok baseok;
set the progress of base classes resolving
ObjcClassDeclaration objc;
Data for a class declaration that is needed for the Objective-C integration.
final bool isBaseOf2(ClassDeclaration cd);
Determine if 'this' is a base class of cd. This is used to detect circular inheritance only.
bool isBaseOf(ClassDeclaration cd, int* poffset);
Determine if 'this' is a base class of cd.
final const bool isBaseInfoComplete();
Determine if 'this' has complete base class information. This is used to detect forward references in covariant overloads.
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
Returns:
ClassDeclaration if found, null if not
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
Returns:
function symbol if found, null if not

Errors prints error message if more than one match

final const bool isCOMclass();
final bool isAbstract();
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.
Returns:
0 vtbl[0] is first virtual function pointer 1 vtbl[0] is classinfo/interfaceinfo pointer
const const(char)* kind();
final void addLocalClass(ClassDeclarations* aclasses);
class InterfaceDeclaration: dmd.dclass.ClassDeclaration;
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

Returns:
false not a base true is a base
const const(char)* kind();
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.
