Destructor

Explore the role of destructors in D programming by understanding how they handle operations at the end of an object's lifetime. Learn to define destructors to manage resources and produce matched XML element tags using constructors and destructors. This lesson helps you grasp how automatic and custom destructors ensure proper cleanup and output formatting.

Destructor definition

The destructor includes the operations that must be executed when the lifetime of an object ends.

The compiler-generated, automatic destructor executes the destructors of all of the members in order. For that reason, as it is with the constructor, there is no need to define a destructor for most structs.

However, sometimes some special operations may need to be executed when an object’s lifetime ends. For example, an operating system resource that the object owns may need to be returned to the system, a member function of another object may need to be called, a server running somewhere on the network may need to be notified that a connection to it is about to be terminated, etc.

The name of the destructor is ~this, and just like constructors, it has no return type.
