An enthusiastic overriding property report range from the new close modifier

Entry to that it modifier prevents a derived category away from further overriding the home. The brand new accessors away from a closed assets also are sealed.

Except for variations in statement and you may invocation syntax, virtual, shut, override, and abstract accessors function exactly like virtual, closed, override and conceptual methods. Especially, the guidelines explained from inside the §fourteen.six.cuatro, §fourteen.six.5, §14.six.six, and §fourteen.six.eight implement since if accessors were methods of a matching form:

• A rating accessor corresponds to a good parameterless approach that have money worth of the home type of plus the exact same modifiers since which includes possessions.
• A-flat accessor represents a technique with a single worthy of factor of the property style of, an emptiness go back sort of, additionally the same modifiers given that who has property.

X try an online understand-only property, Y are an online see-create property, and you can Z is an abstract discover-generate possessions. Once the Z was abstract, the new which has had category A will also be announced conceptual.

Right here, new declarations off X , Y , and you may Z is overriding possessions declarations. For every single property statement just matches the new use of modifiers, particular, and you will identity of your related handed down property. The brand new rating accessor out-of X therefore the set accessor away from Y utilize the base keywords to gain access to the brand new passed down accessors. The newest report out of Z overrides both abstract accessors-therefore, there aren’t any a fantastic abstract form members for the B , and you may B was permitted to be a low-conceptual group. stop analogy

When property is proclaimed once the an bypass, people overridden accessors is going to be offered to new overriding code. At the same time, the stated accessibility away from the possessions otherwise indexer in itself, and of the fresh accessors, should suits that of the overridden affiliate and you may accessors.

fourteen.8.1 Standard

A conference are a member which enables an item or category to include announcements. Customers is mount executable code having situations by the offering knowledge handlers.

A meeting_statement vary from a couple of services (§21) and a valid mixture of the fresh four availability modifiers (§14.step three.6), the latest (§fourteen.step 3.5), fixed (§14.six.step three, §14.8.4), virtual (§fourteen.6.4, §fourteen.8.5), bypass (§14.six.5, §fourteen.8.5), closed (§fourteen.6.6), abstract (§14.six.7, §14.8.5), and you will extern (§14.six.8) modifiers.

The type of a conference statement might be an effective outsource_sorts of (§8.dos.8), and therefore subcontract_form of shall be about since the obtainable given that skills alone (§7.5.5).

14.8 Incidents

A meeting declaration include knowledge_accessor_declarations. However, if it does not, to have low-extern, non-abstract incidents, the fresh new compiler should likewise have her or him automatically (§14.8.2); getting extern situations, the newest accessors are provided on the outside.

A conference statement you to definitely omits knowledge_accessor_declarations describes a minumum of one events-one for every single of your own variable_declarators. The fresh new features and you will modifiers apply at all the players declared from the such a conference_declaration.

When a conference statement includes an enthusiastic extern modifier, the big event is claimed are an outward event. Once the an outward enjoy statement provides no implementation, it is a mistake for it to provide both extern modifier and you will knowledge_accessor_declarations.

It’s an accumulate-go out error getting a varying_declarator regarding an event declaration with an abstract or outside modifier to add a varying_initializer.

A meeting can be utilized once the remaining-hand operand of the += and you may -= workers. These operators can be used, respectively, to add event handlers to help you, or even to dump enjoy handlers off an event, plus the supply modifiers of your own skills control the new contexts when you look at the hence such as for example surgery are permitted.

The actual only real businesses which might be enabled to your a conference by password https://datingranking.net/pl/roksa-recenzja/ which is outside of the type in and that that feel try stated, is += and you may -= . Hence, when you’re such as for example code can add on and take away handlers to possess a meeting, it cannot myself receive otherwise customize the hidden listing of enjoy handlers.

Into the a procedure of one’s mode x += y or x –= y , whenever x was a meeting the consequence of the fresh new process has actually types of emptiness (§.4) (in the place of obtaining sorts of x , on the property value x adopting the project, as for almost every other the += and you will -= workers discussed towards non-feel models). Which suppresses exterior password away from indirectly examining the fundamental outsource away from a meeting.
