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)

enum ClassKind: int;

The ClassKind enum is used in ClassDeclaration AST nodes to specify the linkage type of the class or if it is an anonymous class. If the class is anonymous it is also considered to be a D class.

d

the class is a d(efault) class

cpp

the class is a C++ interface

objc

the class is an Objective-C class/interface

class ClassDeclaration: dmd.aggregate.AggregateDeclaration;

bool stack;

true if this is a scope class

ClassKind classKind;

specifies whether this is a D, C++, Objective-C or anonymous class/interface

Baseok baseok;

set the progress of base classes resolving

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.
