Whenever a meeting report is sold with a fixed modifier, the function is said as a static experiences. Whenever zero static modifier can be acquired, the function is said getting a situation skills.
A static feel isn’t of a specific such as for example, and it is a gather-time error to refer compared to that in the accessors away from a good fixed feel.
A situation experiences is actually on the a given example of a great classification, and this for example is randki sweet pea reached that (§eleven.7.12) about accessors of that feel.
A virtual event report determine that the accessors of that experiences try virtual. The virtual modifier applies to each other accessors out of a conference.
A conceptual enjoy declaration determine that the accessors of feel was digital, however, will not bring a real utilization of this new accessors. As an alternative, non-conceptual derived categories are required to promote their unique implementation having the latest accessors by the overriding the event. Just like the a keen accessor to possess an abstract feel report provides no implementation, it should not give enjoy_accessor_declarations.
A conference statement complete with the conceptual and you will bypass modifiers determine the event is actually abstract and you can overrides a bottom event. The fresh accessors of these an event are also abstract.
Brand new accessors from an inherited virtual experience are overridden when you look at the a good derived class by as well as a meeting report one determine an override modifier. This is also known as an overriding experience statement. Rather, it simply specializes brand new implementations of your own accessors of a preexisting digital knowledge.
An overriding event e usage of modifiers and you may identity due to the fact overridden experiences, around are going to be a character transformation amongst the brand of brand new overriding as well as the overridden enjoy, and you can both the create and take away accessors is going to be given in this the declaration.
An overriding knowledge statement may include the fresh new closed modifier. Usage of it modifier suppress a derived group from next overriding the event. The latest accessors of a shut feel also are sealed.
Apart from variations in statement and you may invocation sentence structure, virtual, close, bypass, and you may abstract accessors behave just like digital, shut, bypass and you will abstract measures. Specifically, the rules demonstrated inside §fourteen.6.cuatro, §14.6.5, §fourteen.six.6, and you can §fourteen.six.seven implement as if accessors had been ways of a corresponding mode. For every single accessor represents a method having one worthy of factor of enjoy form of, a void return type of, while the exact same modifiers due to the fact that has had skills.
14.9 Indexers
A keen indexer are a member that enables an object is indexed by the same exact way due to the fact an array. Indexers is actually proclaimed playing with indexer_declarations:
An indexer_report cover anything from a couple of attributes (§21) and you can a valid combination of the new five accessibility modifiers (§14.3.6), the fresh new (§14.step 3.5), digital (§fourteen.6.4), override (§fourteen.six.5), sealed (§fourteen.6.6), conceptual (§fourteen.six.7), and you can extern (§14.6.8) modifiers.
Indexer e laws and regulations as the approach declarations (§fourteen.6) regarding good combinations regarding modifiers, towards the you to definitely exclusion becoming that fixed modifier isn’t permitted toward a keen indexer declaration.
New modifiers digital , bypass , and you will abstract was collectively personal except in one situation. The latest conceptual and you can override modifiers can be utilized together to ensure a conceptual indexer can be override a virtual one to.
A keen overriding knowledge declaration will not claim a unique experience
Note: Because indexers are made to be used from inside the number feature-particularly contexts, the definition of ability variety of as the defined to have a wide range is also used in combination with an enthusiastic indexer. end note
Except if this new indexer was an explicit program representative implementation, the type try followed by the latest key phrase so it . Getting an explicit screen representative execution, the sort try accompanied by an user interface_type, an excellent ” . “, in addition to search term which . Rather than most other users, indexers do not have member-defined labels.
