metaclass sentence in Hindi

Examples

1. Unlike Smalltalk, the metaclass of the root class inherits from the root class ( usually NSObject using the Cocoa framework ) itself.
2. Metaclasses can be implemented by having classes be first-class citizen, in which case a metaclass is simply an object that constructs classes.
3. Groovy's changes in code through prototyping are not visible in Java, since each attribute / method invocation in Groovy goes through the metaclass registry.
4. Variable order metaclasses, on the other hand, can have instances, one example of variable order metaclass is the class of all fixed order classes.
5. Together this implies that a class in Smalltalk is an object and that therefore a class needs to be an instance of a class ( called metaclass ).
6. By contrast, in ObjVlisp, it is possible to define named metaclasses, and when defining a class one must specify which named metaclass it will instantiate.
7. Like Smalltalk, in Objective-C, class methods are simply methods called on the class object, hence a class's class methods must be defined as instance methods in its metaclass.
8. Classes and metaclasses are always created as a pair : the runtime has functions objc _ allocateClassPair ( ) and objc _ registerClassPair ( ) to create and register class-metaclass pairs, respectively.
9. Thus evaluating Car class results in the metaclass object for Car whose name is Car class ( one can confirm this by evaluating Car class name which returns the name of the metaclass of Car .)
10. Thus evaluating Car class results in the metaclass object for Car whose name is Car class ( one can confirm this by evaluating Car class name which returns the name of the metaclass of Car .)
