What does strong mean in code?

One of the most common mistakes I see made when looking at code is when people use the weak keyword on an instance of a type. Using the weak keyword when an object is created ensures that the Garbage Collector will not automatically release the instance when the last strong reference to that instance is gone. However, it does not prevent the instance from being garbage collected if there are no more strong references to it. The problem with this is that when the garbage collector is running, it tests whether an instance is

What does strong mean in C?

The strong keyword makes the object it’s used on accessible to any other instance of the class. A strong example is a dictionary. If you create an instance of a dictionary, you can only access the contents of the dictionary via the indexer. If you want to access the dictionary itself, you must make a copy of it. You do this by assigning the value returned by the indexer to a new variable.

What does strong mean in objective C?

The strong keyword refers to the retain count in the Objective-C Garbage Collector (GC). The retain count is used to determine when an object is eligible to be deallocated. The retain count is increased when an object is created, and it decreases when the last strong reference to the object is released. If the retain count reaches 0, the object is deallocated. If an object is declared strong, the retain count is increased automatically.

What does strong mean in Java?

In Java, the keyword “strong” stands for a reference to an object. This keyword does not change the object itself, but rather tells the compiler to make the variable that refers to the object as a non-weak reference. A weak reference is one that doesn’t prevent the object from being Garbage collected when there are no other strong references to it. In other words, the object is not accessible anymore, but the reference is just pointing to an object that no longer exists

What does strong mean in C++?

The keyword strong is used in the context of C++ (and C++) to indicate a reference to a variable or a class. This keyword is used to prevent the variable from being automatically deallocated. If a variable is declared with the strong keyword, it means that the instance will not be destroyed automatically even if no references to it remain. Only when the program reaches the end of its execution will the variable automatically be destroyed.
