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...
public static bool InstanceExists (string instanceName, string categoryName, string machineName); 参数 instanceName String 要搜索的性能对象实例。 categoryName String 要搜索的性能计数器类别。 machineName String 要在其上查找该类别实例对的计算机的名称。 返回 Boolean 如果该类别包含指定的性能对象实例,则...
instanceof、isInstance、isAssignableFrom这几个有没有接触过,或者接触过部分? 定义 a instanceof B a是B的实例,B是类或者接口、父类或父接口,即B c = a成立。 B.class.isInstance(a) 这个叫动态等价,效果和上面等价,一般用于检查泛型,如jdk中CheckedMap里面用到这个检查Map里面的key、value类型是否和约定的一...
Method static void Release(const MaterialInstance* materialInstance) 释放材质实例。 Parameters Name Description materialInstance 指向需要释放的材质实例类MaterialInstance的指针。 SetTechnique 注意 该接口已废弃。 Method virtual bool SetTechnique(const String& techniqueName) 切换到指定名字的材质实现方法。
public static bool JScriptInstanceof(object v1, object v2); Parameters v1 Object The object to coerce to the type of object v2. v2 Object The object that has the desired type. Returns Boolean true if v1 can be coerced to the type of object v2; otherwise, false. Applies to Termé...
Either UDP port 1434 is blocked or the static port is blocked, or both. To confirm whether it's the UDP port or the static port, usePortqry. The instance ishiddenfrom the SQL Server Browser service. Method 2: Check the connection by using the PortQryUI tool...
Reworked how the method CInstanceChecker::GetMMFFilename creates the name of the memory mapped filename the code requires for sharing. Now the main instance name appears before the hard coded string. This ensures that the CInstanceChecker class works correctly for terminal sessions i.e. kernel ...
This method will send a ModuleInstanceLoad event. Location constraint: API must be called from a Monitor component (component level < 100,000). This API was introduced in Visual Studio 12 RTM (DkmApiVersion.VS12RTM). C++ 複製 public: static Microsoft::VisualStudio::Debugger::Clr::DkmC...
