    A mode is a procedure or process associated with a class. A method call specifies the object (or, if it is a class style, the class) for which the method is recommended. For example, SomeObject.Free selects the Free-in SomeObject method.

    In methods

  • Above the class declarations, products appear as procedure and function headings that function as direct declarations. Somewhere after the class declaration, but in the same module, every method must be implemented by the defining fact. Suppose the declaration with TMyClass contains the DoSomething method:

    The defining statement for DoSomething must be made later in the module:

    While a type can be declared either in all interfaces or in the module’s implementation section, a good class’s method declarations must be defined in the implementation section.

    At the head of a rights declaration, the name is always qualified by the name associated with the class to which it is to belong. At presentwhile the header may repeat the list of parameters from the class declaration; if so, then the order, type, and parameter names must exactly match the event, and if the method has always been a function, the return value must actually match.

    Method declarations can contain special instructions that are not actually used with other functions or procedures. Directives must only appear in a class statement, not in a definition proverb, and must always be listed in the following order:

  • The binding is virtual, apart from dynamic replacement;
  • Calling convention: register, pascal, cdecl, stdcall or safecall;
  • Warning is an outdated platform or library. For more information about these warnings (notices), see the Notes section.
  • Inherited

    The reserved word plays a special role in the use of polymorphic behavior. It may appear in tactical definitions, with or without a fancy identifier.

    When inherited is followed by an element name, the program is a normala method call, or just a property or niche reference, except that the search for our own referenced element starts from the element’s fast ancestor. covering method of classification. For example, when:

    appears in the method description, it currently calls the inherited Create method.

  • When an inheritance is followed without an identifier, it refers to an inherited method with the same call as the containing method, or because the containing method is a real message.handler, message.handler is inherited from the same message. In either case, inherited does not use explicit scopes, but instead passes the same parameters to the inherited methodology that were called to the enclosing method. Example:

    is usually found in the implementation generated by constructors. It calls the inherited constructor using the same parameters as for the child.

    In the implementation of the method, the Self Records identifier becomes the object on which the handler is invoked. This example is actually an implementation of the TCollection Add routine in the Classes module:

    The Add formula calls the Create method on our class, which is referenced by the FItemClass community, which is always a descendant of TCollectionItem. TCollectionItem.Create takes one parameter associated with the TCollection type, so Add passes that item to the TCollection instance object where Add is called. This is illustrated by the following code:

    I exist for various reasons. First of all, a member identifier declared in this class type can be redeclared as long as the block blocks one of the methods of this class. In this case, that person can access the original partner’s ID as Self.Identifier.

    For more information about interclass methods, see “Class Operators” in the “Class References” section.

    Anchor Method

    anchors can become static (default), virtual, or active. Virtual and dynamic methods can be overridden, and they can be concurrent. These designations come into play whenever a class label variable has a value under the type of the descendant class. You define which configuration is always called when the asset ismethod.

    Static Methods

    delphi 7 abstract error

    Methods are de facto static. When a method is marked static, the declared type (at compile time) of most of the class or object variables used in the method determines which application call to invoke. Drawing methods are static in the following situation:

    delphi 7 abstract error

    With these kinds of declarations in mind, the following code illustrates the actual operation of a method call. On the second call to Figure.Draw, the Figure variable points to something from the TRectangle class, but the phone call calls the Draw last TFigure implementation because the declared type pointing to the Figure variable is And tfigure :

    Virtual Dynamic Methods

    To make a method web-based or dynamic, include an optionally dynamic virtual directive in its declaration. Unlike static paths, virtual and dynamic methods can be in overridden suborders. When an overridden method is classified as , the actual (at runtime) type of most classes or objects used in all method invocations, rather thanThe declared type that points to the variable determines which implementation can be invoked.

    To override a method, you often re-declare it with the override directive. The replacement report must match the ancestor declaration, using the order and type of their respective parameters and their result selector (if any).
