The testobject. Find method is a powerful part of functional tester, making it easier to maintain automated scripts. This introductory article shows you how to introduce testobject. Find to your automation framework.
Part 1: Basics of the testobject. Find Method
The testobject. Find method is a Java? Method, IBM? Rati
it.Yes. When we implement our class, we 'd better overr this method.IDE. In this way, when the garbage collection needs to clear objects, it will executeTo our own finalize ().Therefore, we designed the bottom object. This object needs to be broughtInt value, which is an int value. When finalize () is executedPrint the int value so that we can see which garbage collection is going to clearObject.Public class testobject{Private int Itell;Public
In. net, through reflection, you canProgramSet to perform many operations. Now I want to dynamically load the Assembly and instantiate a class object in the Assembly. Then, the obtained object is converted to a specific class object through forced conversion to call its method.
The Assembly I want to load is very simple. There is only one class, and there is only one public attribute and one public method in the class.CodeAs follows:
Using

. At this time, you have two options: class member variables and usage attributes.
@ Interface TestMem: NSObject {TestObject * m_testObject; // member variableTestObject * testObject; // member variable}The member variables are consistent with the memory management above, but they must maintain a balance between the addition and subtraction of the reference count in different functions. Therefore, you must
know if anyone understands it. Let's use an example to explain it:
1. synchronization object
Public static class testobject {
The synchronization effects of functions A, B, and C are the same, and the essence is to obtain the object lock.
In the method A and B, the lock holder (object) is the object that calls the method, and in the method C, the lock holder (object) is the member variable lock.
Running result:
Print the information once every 2 se
The foreach Statement of C # language (for each in C ++ and for each in Visual Basic) requires the type of each element in the set. Because each element of sorteddictionary
It can be seen that sorteddictionary is similar to a balanced binary search tree (AVL). Since it is a BST, we can certainly traverse it in the middle order. There are two methods:1. For each2. Object. getenumerator

1.Object ClassIn Java development, all classes exist in the form of inheritance, and if a class does not explicitly indicate which class is inherited, it inherits the object class by default.For exampleClass Person {}The above code defines Objectby default, and its complete representation is:Class Person extends object{}In the JDK document,api-> index->java.lang->object looks for the Object class. A complete class should be a method of covering the Object class, and here are some important metho
