14.8.5 Digital, closed, override, and conceptual accessors

Whenever a conference declaration boasts a fixed modifier, the function is alleged to-be a fixed event. When zero fixed modifier can be obtained, the big event is said are a situation experiences.

A fixed experience is not from the a specific instance, and is an attain-go out error to mention to that on accessors out

of good static experience.

A case feel was on the certain exemplory case of a beneficial category, and this particularly will likely be reached because (§eleven.seven.12) regarding accessors of this feel.

An online skills report determine that accessors of the experience is actually virtual. The new digital modifier pertains to one another accessors out-of a conference.

An abstract experience declaration determine your accessors of your knowledge is digital, however, does not give a genuine utilization of the fresh new accessors. As an alternative, non-conceptual derived groups must promote her implementation for the latest accessors because of the overriding case. Since a keen accessor having an abstract feel statement will bring no implementation, they will maybe not offer experience_accessor_declarations.

A meeting report filled with both conceptual and you will bypass modifiers specifies that the feel is conceptual and you may overrides a bottom feel. The newest accessors of these an event are also abstract.

The latest accessors out of a genetic virtual experience will be overridden when you look at the a beneficial derived class from the in addition to a conference report one specifies a keen bypass modifier. This is certainly also known as an overriding experience statement. Alternatively, it really specializes the newest implementations of one’s accessors out of a current virtual experience.

An enthusiastic overriding feel e entry to modifiers and you will label because the overridden experiences, here shall be a personality conversion involving the sorts of the brand new overriding and the overridden event, and you may both the include and remove accessors will be given in this the fresh report.

An enthusiastic overriding event report range from the close modifier. Access to so it modifier suppresses an effective derived classification from further overriding case. This new accessors out of a closed enjoy also are shut.

Apart from variations in statement and you can invocation sentence structure, digital, closed, bypass, and abstract accessors respond just like virtual, close, bypass and you can conceptual methods. Particularly, the guidelines demonstrated in the §fourteen.6.cuatro https://datingranking.net/pl/mennation-recenzja/, §fourteen.six.5, §14.six.6, and you may §fourteen.six.seven apply since if accessors was in fact ways of a matching function. For every accessor corresponds to a method which have a single really worth factor of one’s skills sort of, an emptiness come back particular, and also the same modifiers as which has had skills.

fourteen.nine Indexers

An indexer was a part enabling an item are indexed by in the same way due to the fact a selection. Indexers try declared having fun with indexer_declarations:

A keen indexer_report are priced between a couple of characteristics (§21) and you will a legitimate blend of the newest four accessibility modifiers (§fourteen.3.6), the brand new (§fourteen.step 3.5), virtual (§14.six.4), bypass (§fourteen.6.5), closed (§14.six.6), conceptual (§14.6.7), and you can extern (§fourteen.six.8) modifiers.

Indexer e legislation since the strategy declarations (§14.6) regarding valid combinations of modifiers, to the one exemption being the static modifier is not let with the an indexer declaration.

New modifiers virtual , override , and you will conceptual try mutually exclusive but in one single situation. New conceptual and you may override modifiers may be used along with her making sure that a conceptual indexer can also be override an online you to definitely.

An overriding feel report does not claim a special experiences

Note: Just like the indexers are created to be taken inside assortment element-such as contexts, the expression element sorts of due to the fact defined to possess a selection is also used in combination with a keen indexer. avoid mention

Except if the fresh new indexer is an explicit software associate execution, the kind try accompanied by brand new key phrase this . To have an explicit interface member execution, the kind is actually followed closely by a software_sorts of, an effective » . «, in addition to keywords which . Instead of almost every other people, indexers do not have user-discussed names.
