An interface is a reference type, similar to a class, which can be declared by using interface keyword. Interfaces can contain only constants, method signatures, default methods, static methods, and nested types. Method bodies exist only for default methods and static methods. Like abstract classes...

Function pointers are pointers that point to functions instead of data types. They can be used to allow variability in the function that is to be called, at run-time. returnType (*name)(parameters) typedef returnType (*name)(parameters) typedef returnType Name(parameters); Name *n...

Tkinter ("Tk Interface")is python's standard cross-platform package for creating graphical user interfaces (GUIs). It provides access to an underlying Tcl interpreter with the Tk toolkit, which itself is a cross-platform, multilanguage graphical user interface library. Tkinter isn't the...

A pointer is a type of variable which can store the address of another object or a function. <Data type> *<Variable name>; int *ptrToInt; void *ptrToVoid; /* C89+ */ struct someStruct *ptrToStruct; int **ptrToPtrToInt; int arr[length]; int *ptrToFirstElem = arr; /* For <C99...

Interfaces in Go are just fixed method sets. A type implicitly implements an interface if its method set is a superset of the interface. There is no declaration of intent.

pointer := &variable // get pointer from variable variable := *pointer // get variable from pointer *pointer = value // set value from variable through the pointer pointer := new(Struct) // get pointer of new struct

What we do with HttpServiceLayer class is extend the Http class from angular and add our own logic to it. We then inject that class in the bootstrap class of the application and tell angular that were we import the Http class, in the back to insert the HttpServiceLayer. Anywhere in the code we ...

This feature exists in Scala 2.10.0 and above.

It's up to clients of the class implementing IDisposable to make sure they call the Dispose method when they are finished using the object. There is nothing in the CLR that directly searches objects for a Dispose method to invoke. It's not necessary to implement a finalizer if your object...

An interfaces specifies a list of fields and functions that may be expected on any class implementing the interface. Conversely, a class cannot implement an interface unless it has every field and function specified on the interface. The primary benefit of using interfaces, is that it allows one to...
