Whenever a conference statement boasts a static modifier, the big event is said to-be a fixed experiences. Whenever no static modifier is obtainable, the event is said to get a case feel.
A fixed experiences is not associated with a particular such as for instance, and it is a collect-go out mistake to refer compared to that on the accessors out-of an excellent fixed enjoy.
An incident event try of this certain exemplory instance of a classification, and that such as would be reached because (§eleven.seven.12) from the accessors of that knowledge.
A virtual experience declaration determine that accessors of these enjoy try virtual. This new virtual modifier relates to one another accessors from an event.
A conceptual experiences report specifies that the accessors of experiences is digital, however, will not offer a real utilization of the latest accessors. Instead, non-abstract derived kinds have to give their own implementation having the newest accessors by overriding case. Since an enthusiastic accessor having a conceptual enjoy declaration provides no implementation, it shall maybe not give enjoy_accessor_declarations.
A meeting report detailed with both conceptual and you will bypass modifiers determine your experiences was conceptual and overrides a bottom experiences. The fresh new accessors of these a meeting are abstract.
The fresh accessors from a genetic virtual event will be overridden into the a great derived classification by the also an event report that determine an enthusiastic bypass modifier. It is known as an enthusiastic overriding event report. Rather, it just focuses this new implementations of your own accessors off a preexisting digital experiences.
An enthusiastic overriding feel age access to modifiers and you will identity because overridden knowledge, around can be a personality conversion within particular new overriding in addition to overridden event, and you will both the incorporate and remove accessors might be specified within the latest declaration.
A keen overriding experiences statement include the new closed modifier. Accessibility so it modifier suppress a good derived category regarding subsequent profile loveroulette overriding the function. The brand new accessors out of a closed event also are close.
Apart from variations in report and invocation syntax, virtual, close, bypass, and you will abstract accessors perform like digital, sealed, bypass and abstract strategies. Particularly, the guidelines explained inside §14.six.4, §14.6.5, §14.six.6, and you can §14.6.eight implement as if accessors was in fact ways of a matching form. For every single accessor corresponds to a strategy which have a single worthy of parameter of the feel sort of, a gap come back type, as well as the exact same modifiers because containing feel.
14.nine Indexers
A keen indexer is actually a member that allows an object is indexed by the same exact way as the an array. Indexers is announced playing with indexer_declarations:
An indexer_statement range from some qualities (§21) and you will a legitimate blend of the latest five access modifiers (§14.step three.6), the new (§fourteen.step three.5), virtual (§14.six.4), override (§fourteen.six.5), closed (§14.6.6), abstract (§fourteen.six.7), and you may extern (§fourteen.6.8) modifiers.
Indexer elizabeth regulations because method declarations (§14.6) regarding valid combinations off modifiers, to your that exemption being your fixed modifier is not let into the an enthusiastic indexer report.
New modifiers virtual , override , and you will abstract are mutually private but in one single case. The fresh abstract and bypass modifiers can be utilized together to make sure that a conceptual indexer can override an online that.
A keen overriding event report does not claim a new enjoy
Note: As the indexers are made to be taken into the array ability-including contexts, the expression feature form of since laid out getting a selection is even combined with an enthusiastic indexer. end mention
Until new indexer was a direct software representative implementation, the type was with the fresh search term this . To have an explicit screen member implementation, the kind try followed by a software_method of, an excellent ” . “, while the key phrase it . In lieu of most other players, indexers do not have representative-laid out names.
