Usage of that it modifier prevents a derived category of further overriding the property. The latest accessors of a sealed property also are sealed.
Except for differences in declaration and you will invocation syntax, digital, close, override, and you may abstract accessors react the same as virtual, sealed, bypass and you can abstract strategies. Specifically, the principles described in the §14.six.4, §fourteen.six.5, §fourteen.six.six, and §fourteen.6.7 apply as if accessors was in fact methods of a corresponding form:
- A get accessor corresponds to a parameterless method having income worth of the house or property sort of and same modifiers because the which includes assets.
- An appartment accessor corresponds to a technique having an individual really worth parameter of the home sort of, a gap return method of, and also the same modifiers given that containing property.
X is actually an online comprehend-just assets, Y try an online comprehend-create possessions, and you may Z is an abstract see-write property. As the Z is conceptual, new which has had class A will even be proclaimed conceptual.
Right here, the fresh declarations out-of X , Y , and you may Z is overriding assets declarations. For each assets report precisely fits the newest usage of modifiers, particular, and you can term of the involved passed on possessions. The new get accessor away from X while the lay accessor from Y use the base search term to view the brand new passed down accessors. The newest declaration regarding Z overrides one another conceptual accessors-thus, there are not any a good abstract function members inside B , and B was permitted to feel a low-abstract group. stop analogy
Whenever a property was proclaimed because an enthusiastic bypass, one overridden accessors are going to be offered to the new overriding password. On the other hand, brand new proclaimed access to off the assets otherwise indexer itself, as well as new accessors, shall meets regarding the newest overridden representative and you can accessors.
fourteen.8.step 1 General
A conference was an associate enabling an item or category to provide announcements. Customers can be install executable code to have incidents of the supplying skills handlers.
A conference_declaration are priced between a couple of functions (§21) and a legitimate combination of brand new four access modifiers (§14.3.6), the fresh new (§14.3.5), static (§fourteen.six.step 3, §14.8.4), virtual (§fourteen.6.4, §14.8.5) jak wysÅ‚ać komuÅ› wiadomość na military cupid, override (§fourteen.6.5, §fourteen.8.5), close (§14.six.6), abstract (§14.six.7, §14.8.5), and you may extern (§fourteen.six.8) modifiers.
The kind of a meeting declaration are going to be good delegate_type of (§8.dos.8), hence delegate_sort of might be no less than as accessible as the feel itself (§eight.5.5).
fourteen.8 Events
A meeting statement can include event_accessor_declarations. Although not, when it doesn’t, getting non-extern, non-conceptual incidents, the new compiler will supply them automatically (§fourteen.8.2); to have extern events, the new accessors are given on the exterior.
An event statement you to omits enjoy_accessor_declarations talks of no less than one situations-you to definitely per of adjustable_declarators. New properties and you will modifiers affect all professionals declared by including a meeting_report.
When an event report includes an extern modifier, the function is considered are an external experiences. Since the an external skills report provides no actual execution, it’s an error for it to include both the extern modifier and you will skills_accessor_declarations.
It’s an amass-time error having a varying_declarator away from an event statement with a conceptual otherwise exterior modifier to provide a changeable_initializer.
A meeting can be utilized given that left-hand operand of the += and -= workers. These workers are used, respectively, to install experience handlers so you can, or even lose event handlers out of a conference, while the access modifiers of your event manage the fresh contexts when you look at the hence such operations are permitted.
The only real businesses which can be enabled towards a meeting of the password that’s outside the input which one to knowledge is actually proclaimed, is actually += and -= . Therefore, while you are such as for example password can add and take off handlers to possess a meeting, it can’t yourself see or modify the root set of skills handlers.
Within the a process of function x += y otherwise x –= y , whenever x try a conference the consequence of new process has types of emptiness (§.4) (in the place of having the particular x , towards the property value x adopting the assignment, in terms of other the += and you will -= workers discussed towards the non-skills systems). That it suppresses exterior password off ultimately exploring the underlying delegate out-of an event.
