KJS::InternalFunctionImp Class Reference
#include <function.h>
Inheritance diagram for KJS::InternalFunctionImp:

Detailed Description
Base class for all function objects.It implements the hasInstance method (for instanceof, which only applies to function objects) and allows to give the function a name, used in toString().
Constructors and prototypes of internal objects (implemented in C++) directly inherit from this. FunctionImp also does, for functions implemented in JS.

virtual const ClassInfo* KJS::InternalFunctionImp::classInfo | ( | ) | const [inline, virtual] |
A pointer to a ClassInfo struct for this class.
This provides a basic facility for run-time type information, and can be used to check an object's class an inheritance (see inherits()). This should always return a statically declared pointer, or 0 to indicate that there is no class information.
This is primarily useful if you have application-defined classes that you wish to check against for casting purposes.
For example, to specify the class info for classes FooImp and BarImp, where FooImp inherits from BarImp, you would add the following in your class declarations:
class BarImp : public ObjectImp { virtual const ClassInfo *classInfo() const { return &info; } static const ClassInfo info; // ... }; class FooImp : public ObjectImp { virtual const ClassInfo *classInfo() const { return &info; } static const ClassInfo info; // ... };
And in your source file:
const ClassInfo BarImp::info = {0, 0, 0}; // no parent class const ClassInfo FooImp::info = {&BarImp::info, 0, 0};

You might want to use the helper function ObjectImp::setFunctionName for this.
