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 ...
One subtlety is that the value of a method call ("message") in a cascade is still the ordinary value of the message, not the receiver. This is a problem when you do want the value of the receiver, for example when building up a complex value. This can be worked around by using the special yourself method that simply returns the receiver: [2]
Method overloading, on the other hand, refers to differentiating the code used to handle a message based on the parameters of the method. If one views the receiving object as the first parameter in any method then overriding is just a special case of overloading where the selection is based only on the first argument.
Alternatives are synchronous method invocation and future objects. [4] An example for an application that may make use of AMI is a web browser that needs to display a web page even before all images are loaded. Since method is a special case of procedure, asynchronous method invocation is a special case of asynchronous procedure call.
During compilation of CLI programming languages, the source code is translated into CIL code rather than into platform- or processor-specific object code.CIL is a CPU- and platform-independent instruction set that can be executed in any environment supporting the Common Language Infrastructure, such as the .NET runtime on Windows, or the cross-platform Mono runtime.
An output parameter, also known as an out parameter or return parameter, is a parameter used for output, rather than the more usual use for input. Using call by reference parameters, or call by value parameters where the value is a reference, as output parameters is an idiom in some languages, notably C and C++, [ b ] while other languages have ...
