- struct
BaseClass; -
- bool
fillVtbl(ClassDeclarationcd, FuncDeclarations*vtbl, intnewinstance); - 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
- bool
inuse; - to prevent recursive attempts
- 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 pure nothrow @nogc bool
isBaseOf2(ClassDeclarationcd); - Determine if 'this' is a base class of cd. This is used to detect circular inheritance only.
- pure nothrow @nogc bool
isBaseOf(ClassDeclarationcd, int*poffset); - Determine if 'this' is a base class of cd.
- final bool
isBaseInfoComplete() const; - Determine if 'this' has complete base class information. This is used to detect forward references in covariant overloads.
- final ClassDeclaration
searchBase(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:
Identifier identidentifier to search for Returns:ClassDeclaration if found, null if not - final bool
hasMonitor(); - Returns:true if there's a __monitor field
- final FuncDeclaration
findFunc(Identifierident, TypeFunctiontf); - Find virtual function matching identifier and type. Used to build virtual function tables for interface implementations.Parameters:
Identifier identfunction's identifier TypeFunction tffunction's type Returns:function symbol if found, null if notErrors prints error message if more than one match
- final bool
isCOMclass() const; - final bool
isAbstract(); - int
vtblOffset() 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 void
addObjcSymbols(ClassDeclarations*classes, ClassDeclarations*categories);
- class
InterfaceDeclaration: dmd.dclass.ClassDeclaration; -
- pure nothrow @nogc bool
isBaseOf(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; - int
vtblOffset() 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.
