Instead of using standard .NET parameter types in P/Invoke method definitions (char[], string, etc.) it uses these interface classes in the P/Invoke function calls. For instance, if we consider the above example code, PInvoker would produce a .NET P/Invoke function accepting a .NET interface class wrapping the native char * pointer.
Method chaining is a common syntax for invoking multiple method calls in object-oriented programming languages. Each method returns an object, allowing the calls to be chained together in a single statement without requiring variables to store the intermediate results.
This information includes the method name, the object that owns the method and values for the method parameters. Four terms always associated with the command pattern are command, receiver, invoker and client. A command object knows about receiver and invokes a method of the receiver. Values for parameters of the receiver method are stored in ...
The {{#invoke: params}} module is designed to be adopted by those templates that want to have a deep control of their parameters. It is particularly useful to variadic templates, to which it offers the possibility to count, list, map and propagate the parameters received without knowing their number in advance.
Dereferencing the function pointer yields the referenced function, which can be invoked and passed arguments just as in a normal function call. Such an invocation is also known as an "indirect" call, because the function is being invoked indirectly through a variable instead of directly through a fixed identifier or address.
If the call variability relies on more than the single type of the object on which it is called (i.e. at least one other parameter object is involved in the method choice), one speaks of multiple dispatch. A method call is also known as message passing. It is conceptualized as a message (the name of the method and its input parameters) being ...
A method is a behavior of an object parametrized by a user. Data is represented as properties of the object, and behaviors are represented as methods. For example, a Window object could have methods such as open and close, while its state (whether it is open or closed at any given point in time) would be a property.
A customer visits a store to place an order. This is like the first call. The customer gives to a clerk a list of items, a check to cover their cost and delivery instructions. These are the parameters of the first call including the callback which is the delivery instructions.
