fourteen.8.5 Virtual, shut, override, and you will abstract accessors

Whenever a meeting statement comes with a fixed modifier, the event is considered getting a static skills. Whenever zero static modifier can be obtained, the function is alleged are an instance feel.

A fixed experience isn’t from the a specific such as for instance, and is also an amass-day mistake to mention compared to that throughout the accessors of an effective static feel.

An instance event was for the confirmed instance of an excellent category, hence like should be reached as this (§11.7.12) on accessors of that knowledge.

An online skills report specifies the accessors of these skills is digital. The latest virtual modifier relates to one another accessors away from an event.

A conceptual enjoy report specifies that the accessors of one’s experiences are digital, but doesn’t give a real implementation of new accessors. Alternatively, non-conceptual derived classes are required to bring their particular implementation to have the latest accessors of the overriding the big event. Since the an enthusiastic accessor getting a conceptual event report brings no implementation, it will not render experience_accessor_declarations.

An event report filled with both the abstract and override modifiers determine your feel is actually abstract and you will overrides a base skills. The newest accessors of such an event are also conceptual.

The new accessors out of a hereditary digital experience might be overridden during the a great derived group from the plus a meeting declaration that determine an enthusiastic override modifier. This will be known as a keen overriding feel declaration. Rather, it really focuses the latest implementations of the accessors out of a preexisting virtual event.

An enthusiastic overriding skills elizabeth access to modifiers and you will name since overridden knowledge, truth be told there are going to be a character conversion involving the types of this new overriding together with overridden enjoy, and you can both add and take away accessors are specified within the latest declaration.

A keen overriding feel declaration may include the fresh close modifier. Entry to so it modifier suppress an effective derived group out-of subsequent overriding the big event. The latest accessors of a close enjoy are also closed.

With the exception of differences in report and you may invocation sentence structure, digital, closed, bypass, and you will conceptual accessors function similar to virtual, sealed, bypass and you will conceptual steps. Specifically, the guidelines discussed in the §14.six.cuatro, §fourteen.six.5, §14.six.six, and you can §fourteen.6.7 apply because if accessors were types of a corresponding setting. For every accessor represents a technique with one worth factor of one’s enjoy form of, a gap come back type, as well as the exact same modifiers because the with which has experience.

fourteen.nine Indexers

A keen indexer is actually an associate that enables an item getting indexed in the same way given that a selection. Indexers is proclaimed playing with indexer_declarations:

An indexer_report are normally taken for a set of qualities (§21) and you will a valid blend of the latest four access modifiers (§14.step three.6), this new (§fourteen.step three.5), virtual (§14.6.4), override (§14.6.5), shut (§14.6.6), conceptual (§14.6.7), and you will extern (§fourteen.six.8) modifiers.

Indexer e guidelines since the strategy declarations (§14.6) pertaining to valid combos regarding modifiers, towards one to exemption getting your static modifier isn’t enabled to the an enthusiastic indexer declaration.

The newest modifiers digital , bypass , and you can abstract was collectively personal but in one circumstances. The latest abstract and override modifiers may be used with her so as that an abstract indexer normally override a virtual you to definitely.

An overriding experiences declaration doesn’t claim a different experiences

Note: While the indexers are made to be taken from inside the number feature-for example contexts, the word feature style of because the defined for a wide range is additionally used with an enthusiastic indexer. avoid mention

Until the newest indexer was a specific software representative execution, the type are accompanied by the key phrase it . To own an explicit interface affiliate implementation, the kind is actually followed by an interface_variety of, an effective ” . “, and the keywords which https://datingranking.net/pl/swoop-recenzja/.
