Now all of ouranimal document instanceshave a findSimilarTypes method available to it. And then: Addingstatic methods to a Modelis simple as well. Continuing with our animalSchema: //assign a function to the "statics" object of our animalSchemaanimalSchema.statics.findByName =function (name, ...
The static method is as a normal function. Only has the name related to the class. So that it cannot access the class variable and instance variable. You can call the function viaClassName.method_name Magic method And there is a special method called the magic method. The magic method is ...
After all a non static method is called by an instance of the class and in turn it can call a static method. I do agree with your fact that it doesn't make sense calling a static method with the instance of the class but at the same time it doesn't make sense that a static meth...

InstanceMirrorKlass对象用于表示特殊的java.lang.Class类,增加了一个静态属性_offset_of_static_fields,用来描述静态字段的起始偏移量。定义如下: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 staticint _offset_of_static_fields; 只所以增加这个属性,是由于java.lang.Class类比较特殊。正常情况下,HotSpot使用...
If I use a static method of the class, does SAP load just this method into the memory OR entire class (methods, attributes)? Actually I don't want multiple instances and I don't want static methods because of this memory issue! Let's say we have a Class and all methods are instanc...
