true if this is a scope class

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

set the progress of base classes resolving

ObjcClassDeclarationobjc;

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

final pure nothrow @nogc boolisBaseOf2(ClassDeclarationcd);

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

pure nothrow @nogc boolisBaseOf(ClassDeclarationcd, int*poffset);

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

final boolisBaseInfoComplete() const;

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

final ClassDeclarationsearchBase(Identifierident);

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:

Identifierident identifier to search for

Returns:

ClassDeclaration if found, null if not

final boolhasMonitor();

Returns:

true if there's a __monitor field

final boolisCOMclass() const;

intvtblOffset() const;

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(char)*kind() const;

final voidaddObjcSymbols(ClassDeclarations*classes, ClassDeclarations*categories);

classInterfaceDeclaration:dmd.dclass.ClassDeclaration;

pure nothrow @nogc boolisBaseOf(ClassDeclarationcd, 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(char)*kind() const;
intvtblOffset() const;: 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.
