Delphi可以似java的static方法,即不需要class的例就可以直接用方法
如:

[解决办法]
可以，类函数前加 class前缀，前提是此函数与类实体无关。
如：
TObject = class
constructor Create;
procedure Free;
class function InitInstance(Instance: Pointer): TObject;
procedure CleanupInstance;
function ClassType: TClass;
class function ClassName: ShortString;
class function ClassNameIs(const Name: string): Boolean;
class function ClassParent: TClass;
class function ClassInfo: Pointer;
class function InstanceSize: Longint;
class function InheritsFrom(AClass: TClass): Boolean;
class function MethodAddress(const Name: ShortString): Pointer;
class function MethodName(Address: Pointer): ShortString;
function FieldAddress(const Name: ShortString): Pointer;
function GetInterface(const IID: TGUID; out Obj): Boolean;
class function GetInterfaceEntry(const IID: TGUID): PInterfaceEntry;
class function GetInterfaceTable: PInterfaceTable;
function SafeCallException(ExceptObject: TObject;
ExceptAddr: Pointer): HResult; virtual;
procedure AfterConstruction; virtual;
procedure BeforeDestruction; virtual;
procedure Dispatch(var Message); virtual;
procedure DefaultHandler(var Message); virtual;
class function NewInstance: TObject; virtual;
procedure FreeInstance; virtual;
destructor Destroy; virtual;
end;
