Whenever a meeting report has a static modifier, case is claimed getting a static enjoy. When no fixed modifier can be obtained, case is said to-be an incident event.

A fixed enjoy isn’t of this a particular particularly, and is also an attain-day mistake to mention to that particular regarding accessors out of good static experiences.

A case experiences is actually on the a given exemplory instance of good classification, and this including are going to be utilized as this (§11.seven.12) regarding the accessors of that event.

A virtual experiences declaration specifies that the accessors of this experiences is actually digital. The fresh new virtual modifier pertains to each other accessors from an event.

A conceptual event statement specifies that the accessors of the experiences try digital, but does not render an actual implementation of the newest accessors. As an alternative, non-conceptual derived groups are required to offer their own implementation having this new accessors of the overriding the event. Just like the an enthusiastic accessor for a conceptual event statement will bring no implementation, they should not give knowledge_accessor_declarations.

A conference statement that includes both conceptual and you can override modifiers specifies the enjoy is abstract and you can overrides a base skills. This new accessors of such a meeting are also abstract.

This new accessors from a genetic digital event will be overridden when you look at the good derived category by and a conference statement one determine an enthusiastic bypass modifier. This is also known as an overriding experiences report. Instead, it really focuses the latest implementations of your accessors of a preexisting virtual knowledge.

A keen overriding skills e the means to access modifiers and you may title given that overridden experiences, around is going to be a character conversion involving the variety of the newest overriding together with overridden knowledge, and you can both add and remove accessors would be given within this brand new statement.

An enthusiastic overriding enjoy declaration may include the fresh new shut modifier. Entry to it modifier inhibits a good derived class out of next overriding case. New accessors of a sealed enjoy are close.

Except for differences in statement and you may invocation syntax, virtual, shut, override, and you can abstract accessors behave exactly like digital, closed, override and you will abstract methods. Especially, the principles discussed within the §14.6.4, §14.6.5, §fourteen.6.six, and §14.six.7 pertain because if accessors were types of a matching function. For every single accessor corresponds to a strategy with just one well worth parameter of your own knowledge sort of, a void return particular, and the same modifiers because that has had experience.

fourteen.9 Indexers

A keen indexer is actually a part which allows an object as indexed by exactly the same way once the a selection. Indexers is stated having fun with indexer_declarations:

An enthusiastic indexer_statement consist of a collection of attributes (§21) and you will a valid blend of the fresh new four availability modifiers (§fourteen.3.6), the brand new (§14.step three.5), virtual (§14.6.4), bypass (§fourteen.6.5), closed (§14.six.6), abstract (§fourteen.6.7), and extern (§fourteen.6.8) modifiers.

Indexer e rules due to the fact method declarations (§14.6) regarding appropriate combinations off modifiers, toward you to definitely exemption are your fixed modifier is not enabled into a keen indexer report.

The latest modifiers digital , bypass , and you may abstract are mutually exclusive except in one single situation. The new conceptual and you can bypass modifiers can lovestruck be utilized with her in order for an abstract indexer can bypass a virtual one to.

A keen overriding experiences declaration will not declare a new experiences

Note: As indexers are designed to be used into the selection function-such as contexts, the term ability style of due to the fact discussed getting a selection is even combined with an indexer. prevent note

Until the latest indexer is an explicit user interface associate implementation, the type try followed closely by brand new keyword which . Having a direct interface user implementation, the kind is actually accompanied by a screen_kind of, a beneficial ” . “, together with keyword this . Rather than almost every other users, indexers don’t have affiliate-laid out names.
